If the car charger. How to make battery charger

27.09.2019

In the process of engine operation accumulator battery () regardless of the type (serviced or maintenance-free battery) recharges from automobile generator. To control the battery charge on the generator, a device called the relay controller is installed.

The operation of the car in the winter often involves short trips, the inclusion of a large amount of energy-intensive equipment (heated mirrors, glasses, seats, etc.) the load on the battery increases significantly. At the same time stay from the generator and compensate for the loss spent on the launches, the battery simply does not have time. Taking into account the above, optimally fully charge the battery with a charger to 100% at least once a year before the onset of cold.

We add that in case of problems with the start of the engine, due to the presence of motor malfunctions (problems with fuel equipment, etc.), the owner has much longer and more intensively twist the starter. In such cases, to charge the battery by an external charger will need much more often.

Charging the battery charger

To know how to charge the car's maintenanceable battery charger, as well as charging the battery of the type served, you must follow certain rules. Charger (memory, external charger Picky, tripsaged device) is actually a condenser charger.

Car battery - DC source. During the connection of the AKB, the polarity must be observed. For this, the plus and minus terminal connectivity is indicated by the plus and minus sign ("+" and "-") on the battery. Point conclusions have similar labeling, which allows you to correctly connect the battery to the charger. In other words, the "plus" of the battery is connected to the "+" charger terminal, minus on the battery connects to the "-" zoom output.

Pay attention to the random change of polarity will result in the battery discharge instead of charge. It should also be borne in mind that a deep discharge (the battery is fully planted) may in some cases output the battery failure, as a result of which it may not be possible to charge such ankb using a charger.

It is also necessary to take into account that before connecting to the charger, the battery must be removed from the car and thoroughly clean from possible contaminants. The flows of acid are well removed with a wet rag, which is wetted in a solution with soda. For the preparation of the solution, 15-20 grams of soda at 150-200 grams of water are sufficient. The presence of an acid will indicate the foaming of the specified solution when applied to the AcB body.

As for the accumulated batteries, traffic jams on the "banks" for the pouring of the acid should be unscrewed. The fact is that during charging in the battery, gases are formed that need to provide free output. You should also check the electrolyte level. When the level decreases below the norm, the distilled water is made.

What voltage charge the car battery

Let's start with the charging of the battery involves the flow of such a current on it, which is not enough battery for a complete charge. Based on this approval, you can answer questions by way to charge the car battery, as well as how much you need to charge the car battery charger.

In the event that a battery with a capacity of 50 amps-hours is charged by 50%, then at the initial stage, the charging current should be installed 25 A, after which this current must be reduced dynamically. By the time of the complete charge of the battery, the current flow should stop. Such a principle of operation underlies the automatic chargers, with which the car battery is charged on average for 4-6 hours. The only minus such memory is their high cost.

It is also worth highlight semi-automatic type chargers and solutions that suggest a fully manual setting. The latter are most affordable and widely represented on sale. Taking into account the fact that the battery is usually discharged by 50%, you can calculate how much a car battery is charged, and also to understand how much the car battery is maintained.

The basis for calculating the charge time of the battery is the battery capacity. Knowing this parameter, the charge time is simply calculated enough. If the battery has a capacity of 50 a h, then for complete charging you need to submit no more than 30 a. On the charger, 3a is set to the charger, which will require ten hours to complete the battery charging charger.

To 100% to be sure that the battery is fully charged, after 10 hours you can set a current of 0.5 a, after which it continue to charge the battery for another 5-10 hours. This method of charge does not represent hazards for automotive batteries that have a large container. The minus can be considered the need to charge acb about a day.

To save time and rapid battery charging, you can set 8 a, after which it is charged about 3 hours. Upon the expiration of this period, the charge current decreases to 6 A and the battery is charged with this current for another 1 hour. As a result, it will take 4 hours for charging. Note that this charging mode is not optimal, since the battery is desirable to charge a small current to 3 A.

Charging a large current can lead to recharge and excess battery heating, as a result of which its resource is significantly reduced. It also should also be noted that the use of battery charge methods, which are aimed at minimizing the negative process of plates sulfate, do not have noticeable positive results.

Proper battery operation depending on its type (serviced and maintenanceable), the exclusion of deep discharge and timely charging with the help of the memory allow acid accumulator It works in 3-7 years.

How to estimate the condition and charge of a car battery

Proper charging and a number of conditions that need to be observed during the operation of the automotive battery are capable of providing normal engine launch even in extremely low temperatures. The main indicator of the status of the AKB is the degree of its charge. Next, we will reply, how to find out if the car battery is charged.

Let's start with the fact that some batteries models have a special color indicator on the battery itself, which indicates that the battery is charged or discharged. It is worth noting that the specified indicator is a very approximate indicator, according to which it is possible to determine only the need for recovery. In other words, the charge indicator may show that the battery is charged, but the start current at negative temperatures is not enough.

Another way to determine the degree of battery is the measurement of the voltage at the conclusions of the battery. This method Also allows us to quite approximately to assess the condition and degree of charge. To measure the battery, you will need to remove from the car or disconnect from the memory, after which you need to further wait about 7 hours. The outdoor temperature has no fundamental importance.

12.8 B-100% charge;
12.6 B-75% charge;
12.2 in 50% charge;
12.0 B-25% charge;
Fall voltage less than 11.8 V indicates a full battery discharge.

You can also check the battery charge degree without waiting. To do this, the voltage at the conclusions of the battery must be measured with the help of so-called loading forks. This method is more accurate and reliable. The specified plug is a voltmeter, in parallel with the voltmeter conclusions, resistance is connected. The amount of resistance is 0.018-0.020 Ohm for the battery with a capacity of 40-60 amperes.

The plug must be connected to the corresponding outputs on the battery, after which 6-8 seconds. Fix readings that displays a voltmeter. Next, you can estimate the charge of the battery voltage using the load plug:

10.5 V - 100% charge;
9.9 in - 75% charge;
9.3 in - 50% charge;
8.7 in - 25% charge;
The indicator is less than 8.18 V - the full discharge of the AKB;

You can also make measurements in the absence of a loader without removing the battery with a car. The battery must be connected to the on-board network. vehicle. Then it will be necessary to give a load on the battery through the inclusion of dimensions and far Light Head optics (for cars with regular halogen lamps). Headlight light bulbs have a capacity of 50 W, the load is obtained about 10 A. The voltage of a normally charged battery in this case should be about 11.2 V.

The following way, which allows you to check the battery charge, is the measurement of the voltage at the battery outputs at the moment when it is produced launch of DVS. Measurement data can be considered reliable only under the condition of a working starter normally.

At the time of the start, the voltage indicator should not be lower than the mark of 9.5 V. The voltage drop below the specified mark means that the battery was greatly discharged. In this case, its charging is required using the memory. This method of checking also allows you to identify starter malfunctions. The car is installed obviously good and 100% charged battery, after which it is measured. If the voltage on the terminals of the AKB at the time of launch will fall below 9.5 V, then the problems with the starter are obvious.

Finally add that measurements different ways Support the fixation of oscillations in the share of Volta. For this reason, increased requirements are put forward to the voltmeter. The accuracy of the device is extremely important, since the slightest error even in one or two percent will lead to an error in measuring the degree of charge of the battery by 10 -20%. For measurements, it is recommended to use devices with a minimum error.

How to charge a fully discharged car battery

A frequent cause of a deep discharge of AKB is a banal inattention. Often it is enough to leave a car with enabled dimensions or headlights, salon lighting Or a magnetic for 6-12 hours, after which the battery turns out to be fully discharged. For this reason, many car owners are interested in the question whether it is possible to restore a fully discharged battery.

As is known, the full discharge of the battery strongly affects the battery life, especially if we talk about the maintenance-free battery. Car battery manufacturers indicate that even one full discharge It happens enough to exit the battery. In practice, relatively new batteries manage to restore at least 1 or 2 times after their complete discharge without significant loss of operational properties.

To begin with, it is necessary to determine how much the battery was discharged, using one of the above methods. You can also immediately put the battery for charging. Next, a fully discharged battery must be charged in the mode recommended by the AKB manufacturer. The standard is the supply of the charge current at a mark 0.1 from the total battery capacity.

A fully planted battery is charged with such a current of at least 14-16 hours. For example, consider charging the battery with a capacity of 60 amps-hours. In this case, the charge current must be on average from 3 A (slower) to 6 A (faster). A fully discharged automotive battery is correctly charged by the smallest current, and as long as possible (about a day).

When the voltage on the terminals of the battery no longer increases for 60 minutes. (subject to filing the same charging Tok.), Then the battery is fully charged. Unqualified batteries With a complete charge, the voltage value is assumed at a mark of 16.2 ± 0.1. B. It should be borne in mind that such a voltage value is standard, but it has a dependence on the battery capacity, charge current, electrolyte density in the battery, etc. Any voltmeter is suitable for measurement, regardless of the error of the device, because it is necessary to measure the constant, and not exact voltage.

What to charge the car battery if there is no charger

Most. simple way Charging the battery is the launch of the car by the "cigarette" method from another car, then you need to move by car for about 20-30 minutes. For the efficiency of charging from the generator, it is assumed either dynamic ride on increased gears, or movement on "Nizakh".

The main condition is to maintain crankshaft revolutions at about 2900-3200 rpm. On the specified revs, the generator will provide the necessary current that will allow you to recharge the battery. Note that this method is suitable only under the condition of partial, rather than a deep discharge of the AKB. Also, after the trip, it will still need to implement the full battery charge.

Quite often, motorists are interested in what else can be charged the car battery, except for the memory. Most often as a replacement is supposed to use chargers that charge mobile phones, tablets, laptops and other gadgets. Immediately note that these solutions do not allow the car battery without a number of manipulations.

The fact is that the main condition for flowing from the charger to the battery is that the output of the memory should be present, which will be more voltage on the battery outputs. In other words, at the voltage of the battery outputs 12 in the output voltage of the charger, 14 V. Regarding various devices, the voltage of their batteries often does not exceed 7.0 V. Now imagine that there is a charger from the gadget that has the required voltage 12 B. The problem will still be present, since the resistance of the car's battery is measured in the whole ohmas.

It turns out, charging from mobile device The battery outputs will actually be a short circuit of the charging power supply block. The block will be triggered in the block, with the result that such a zoom will not give a current on the battery. Subject to the absence of protection, the likelihood of a power supply unit from a significant load is high.

It is worth adding that the car battery should also not be charged from various power supplies, which have a suitable output voltage, but they are constructively lacking the ability to adjust the amount of the current current. Only a special memory for the car's battery represents such a device that has at its output the desired voltage value and current to charge the battery. In parallel with this, there is the possibility of controlling the permanent current.

Homemade memory for car battery

We now turn from the theory to practice. Let's start with the fact that you can make a battery charger from a third-party device with your own hands.

Please note that these actions represent a certain danger and are performed exclusively at their own risk. The resource administration does not bear any responsibility, information is presented solely for informational purposes!

There are several ways to manufacture a memory. Let's superficially consider the most common:

The manufacture of a charger from the source, which at its output has a voltage of about 13-14 V, and is also able to provide current force more than 1 amp. For such a task, the laptop power supply is suitable.
Charging from ordinary household electrical outlet 220 volt. To do this, you will need a semiconductor diode and incandescent lamps that are consistently connected to the chain.

It should be borne in mind that the use of such solutions means charging the ACB by means of a current source. As a result, constant control of the time and time of the battery charge is required. This control It is performed using regular stress measurements on the battery terminals or counting the time on which the battery is charged.

Remember, the recharge of the battery leads to an increase in the temperature inside the battery and the active release of hydrogen and oxygen. The boiling of the electrolyte in the banks of the battery causes the formation of an explosive mixture. In the event of an electrical spark or the appearance of other sources for fire, the battery can explode. A similar explosion can lead to fires, burns and injuries!

Now pointed attention in the most common way. independent manufacture Memory for car battery. We are talking about charging from the Laptop BP. To implement the task, certain knowledge, skills and experience in the assembly area of \u200b\u200bsimple electrical circuits are needed. Otherwise, the optimal solution will refer to those skilled in the art, to purchase a ready-made charger or replace the battery to a new one.

The scheme itself is quite simple. Ballast lamp is connected to the BP, as well as the outputs of the homemade memory are connected to the outputs of the AKB. As a "ballast", a lamp will be required with a small face value.

If you try to connect the BP to the battery without using the ballast light bulb, then you can quickly output as the power supply itself and the battery itself.

You should step by step to select the desired lamp, starting with the minimum denominations. To begin with, you can connect a low-power light bulb of the rotation repeater, then a more powerful turning lamp, etc. Each lamp should be checked separately by connecting to the chain. If the light is on, then you can switch to the connection of the analogue, more power. This method will help not output the power supply. Finally, add that the combustion of the ballast lamp will be evidenced by the charge of the battery from such a self-made device. In other words, if the battery is charging, then the lamp will burn, even if it is very dull.

New battery It should be fully charged and operational, that is, it assumes an immediate installation on the car to start further operation. Before purchasing, it is necessary to check the ACB for a number of parameters:

housing integrity;
stress out of the outputs;
checking the electrolyte density;
date of manufacture of AKB;

At the initial stage, it is necessary to remove the protective film and inspect the body for cracks, drills and other defects. In case of detection of the slightest deviations from the norm, the battery is recommended to replace.

Then the voltage is performed on the terminals of the new battery. You can measure the voltage by a voltmeter, while the accuracy of the device does not matter. Voltage should not be below 12 volts. The voltage rate of 10.8 volts indicates that the battery is completely discharged. Such an indicator is invalid for a new battery.

The electrolyte density is measured using a special fork. Also, the density parameter indirectly indicates the battery charge level. The final stage of the verification becomes determining the battery output date. Batteries that were released 6 months. Back and more from the day of the planned purchase should not be purchased. The fact is that ready-to-use acb has a tendency to a self-disconstruction. For this reason, for long-term storage, the battery must be prepared in advance, but in this case the battery can no longer be considered a new finished product.

It turns out that the answer to the question is whether it is necessary to charge a new battery for the car, it will be negative. A new battery is charged there is no need. If the battery planned to buy is discharged, then it may be simply an old, used or occurs a production marriage.

The transformer devices are that it, transforming a current from the network to meals for, does not demonstrate the ending charging and does not allow to understand how much it remains until its end. The time for charging varies depending on the novelty and the type of battery, and if you charge the battery for too long, he simply can spoil. In this sense, pulse chargers that have an indicator or timer, which are a charge limiter are much more convenient.

Pulse devices also have drawbacks - for example, a chargeless non-discharged battery, you risk recharging it and contribute to a decrease in battery life and its performance.

Also there are charging on microprocessor control with the prevention of random recharge, but despite their high reliabilityFor cellular such charger, there is practically no. In addition, such chargers are very expensive and are not suitable for all types of batteries.

Purchase the charger corresponding to the power specified in the characteristics, the power required to charge your phone. Also, the charger connector must approach the phone to the phone to prevent damage to the machine.

If your phone supports charging from the computer - use this convenient feature: it eliminates the risk of recharging and supports the battery in good conditionAnd also allows you to simultaneously charge the phone and use it content through the computer interface.

The power adapter is a device that is used to power the laptop, a telephone or other portable device and charging its battery. Basically, all these devices are equipped with regular power supplies, but sometimes there are situations when it is necessary to acquire a new one. In this case, it is necessary to choose the right type and model of the adapter.

Instruction

Start by searching for information on the model of your portable device. Be sure to find a list of all models of power adapters that can be used with a similar brand. Copy the information found in the text or create a table in Excel to produce and optimal option.

Determine the type of power connector on your portable device. The fact is that sometimes even the devices of the same brand have different connectors. Source in the adapter table all unsuitable devices. This stage is very important, since in case of an improper connection, the battery may fail.

Compare the output voltage of the power adapter with the required voltage to power the portable device. It must coincide, otherwise there will be a breakdown of the device.

Soon, a large number of motorists will encounter the need to charge the battery. A charger for a car battery - must be necessarily for each driver and the presence of it is always necessary, regardless of the time of year and operation of the vehicle. In this article, we will tell you how to choose a charger for a car battery.

How to choose a charger for a car battery

Each car owner must have their own charger, as surely there are periods when your car can not be operated for a long time, which means that the battery will be discharged. Especially the battery needs to be charged in winter, despite the fact that the car is operated or not, the presence of a charger in this case is simply necessary. If you have become a happy owner of the car, then you will have any questions about the selection of the charger, we will try to answer them.

Types of charger
Chargers are divided into two types:

Chargers;

Start-charging.

Charging device
Simple chargers are carried out solely charging the battery and it is possible to maintain charging, without any additional functions.

Punchers
Starting devices can perform two functions: charging the battery and start the engine of the car. If everything is clear with the charging function, then the starting function, probably, new questions will cause several questions. As you know, in order to start a car, you need a large battery charge, respectively, if the battery is discharged, you cannot start the machine until you charge your battery to a certain level. The starting device will help you to start a car with a fully discharged battery, due to the fact that such devices can give a current several times more than a simple charger. But such devices have large dimensions and much harder than ordinary charging devices, and they are more expensive.

Charging Tok
The first thing you need to pay attention is the voltage that gives the charger, it must match the battery operating voltage. Charger charging current must be no more than 10% of the battery capacity, or be able to adjust it. Since most accumulators in cars have a capacity of 65A / h, then the battery must be supplied to the charging current of not more than 6,5 amper. Battery charging is best produced by a current of 5% of the battery capacity, that is, again, if the battery capacity is 65a / h, then it is recommended to let the current in the 3.2 sap. With such a current you will get the most deep and complete charge of the battery.
Chargers have both adjustable flow supply and constant. When the charging current is adjustable, you can adjust the current strength, and if there is no such possibility, the charger is charging the battery on the optimal modes, which is actually very useful for the battery.
The output voltage of the charger for the automotive battery should be 12 volts.

Additional functions
Despite the fact that most modern chargers are protected from overheating and protection against incorrect connection of the CLEM, specify the availability of these functions in the selectable charger.
Pulse battery chargers allow you to charge the battery with a deep discharge, this is a good and useful possibility, the presence of which will be very useful.

If you are well versed in electronics, you will be interested to look at the charger diagram for the car battery. Most chargers have the following scheme:

If you need a charger in order for simply it, and for a long period of time you did not have to charge my battery, we recommend purchasing the simplest budget model "Charging".
Those who "live a car" likes to control the charging process and have a functional charger, we will recommend to stop your choice on a commissioning device, which will have a built-in ammeter, the ability to adjust the charging current and other functions.
Drivers who are not often, but, nevertheless, face the need to charge and recharging the battery, but at the same time like simplicity and functionality, we will recommend electronic automatic chargers, without "unnecessary" indicators, switches and other "Soviet" functions.

Charger Operation Rules

Probably, the principle of charging a car battery is familiar to everyone, but in this procedure there are several nuances that we will tell you below.
Charge the battery is best in the garage or on the covered area. In extreme cases, the battery is charged on the street, in warm and dry weather.

When you need to charge the battery charger
So, the car battery is necessary only under specific conditions and situations, just do not need to do it. There is a generator in the car, which when operating the engine converts mechanical energy into electrical. Thanks electrical EnergyThe generator received by the generator is powered by the entire electrical equipment of the car, including the battery is charging. Therefore, if you often travel by car and travel rather last time, then your battery will be fully charged.
The battery must be charged in the following cases:

If the indicator is on dashboard indicates that the battery is in a discharged state;

The machine will not start, and there is no sound of the starter;

The car was in a simple time;

With prolonged and unsuccessful attempts to start a car.

In the first case, when the dashboard indicator informs you that the battery is in a discharged state, in principle, you can do without charging it - if the car will decide on my own, how it was mentioned above, he will be charged the generator. If you have to often join the engine or go to a country trip, then, of course, the battery must be recharged.

If the machine does not start, and the starter sound is not heard, most likely, the battery power is not enough to start the starter. In this case, you need a battery to charge a bit or if you have a commissioning device, then use it, so that the conversion of the car and after a while (giving a little charge a battery) go to the path.

If you did not go for a long time by car, especially if you have not been exploited a car in winter time years, then the battery must be recharged at least 1 time per month. If the battery is old, was in a cold garage or at all the car in a simple is in frosty weather on the street, then check the level of its charging and charge - you need several times a month.
Well, the last, if you tried to start a car several times - and unsuccessfully, with the reason that the engine does not start, is not a battery, it will need to be charged. Since it takes a large amount of battery power to start the engine, and if you tried the engine several times, the battery will probably be in a discharged state.

Connect the charger to the battery
Before connecting the charger to car battery, Be sure to muffle the car engine if it was running. Most modern chargers do not require the automotive power terminals from the battery. That is, you only need to drown out the engine, remove the right terminals are unnecessary. Inspect the battery: there is no electrolyte hernel, as well as there is no moisture on the battery.

Now proceed to connect the charger to the battery. If you did not remove the car terminals, then the terminals of the charger must wear over the automotive. Metal "tongs" of the charger terminals should cover the metal part of the automotive terminals and well be fixed on them. If automotive terminals were removed from the battery, then the charger terminals are put on directly on the battery terminals.

Connect the charger to the battery is necessary as follows: first it is necessary to connect "+" the red terminal of the charger to the "+" battery, then connect the "-" black terminal of the charger to the "-" battery. After that, check whether the terminals are firmly. Next, insert the charger's plug into the socket when the charger turns on, select the necessary mode of its operation in accordance with the instructions for it.

Turning off the charger occurs in the reverse sequence of connection, that is, you first translate the charger to standby mode, then turn it off from the power supply network, then remove the "-" (black terminal) and follows "+" (red).

Charging car battery charger
Now let's talk in more detail about charging the battery. After the charger is connected to the battery, you must select the charging mode - in the automatic charger, or configure the charging parameters in the usual charger. If everything is clear with the modes, then to charge the battery with a regular charger, you will probably need to install the battery charging current.
Do not charge the battery with high current (or the "Boost" mode), despite the fact that you can quickly charge the battery, it will very negatively affect the battery itself. Try not to use this feature of the charger, or at least use it in the most extreme case.

Do not allow frequent and deep battery discharges. If the car is in a long simple - charging the battery.
