Many motorists, faced for the first time with the problem of battery discharge the automotive battery and charge it on their own solutions, ask the following questions: "How current to charge the battery?".In order to implement this plan, you must first have a start-up or battery charger that allows you to convert the current supplied from the usual outlets in 220, in the current, which has a much lower voltage - 15V.Measuring the parameters of voltage 15V considered optimal to carry out high-quality battery charging, while not violating its system.
Asked about how current to charge the battery, first of all, you must determine the choice of method of charging the battery.
- method DC.With this approach, you need to constantly make adjustments to the current, which is fed to the charge.For example, calculations are made to find out how current to charge the battery 60 A / h capacity.Power is calculated from the current ratio of 1:10 on the capacity of the battery.In this example, it is equal to 6 amps.It is not allowed to file a current that is higher than 6 amperes, as it can harm the system battery.Less force is permitted to use the battery 60 A / h, but in this case time for a full charge increases as increases and efficiency of the work performed.
How to determine the full charge?Once the battery is charged, it will start to release gases.This is a sure sign that the battery is fully charged and ready for use.Another sign of a full charge - is the stability of the voltage indicators for an hour or more.Improving the efficiency of the charge will be the higher, the more current will be reduced at the end of the charge.To do this, before the battery is fully charged, you must gradually reduce the strength of the current (for the index 14.4 energized 3 Ampere).Such exposure increases the battery voltage.
- method DC.This voltage regulation is not necessary, but the question of how the current to charge the battery, remains relevant.The battery is connected to a continuous voltage, wherein the current is produced mechanically size equal to the current capacity of the battery, and charge with the lapse of time is reduced, and may fall to the level "0".This technique is used in most of the batteries, which have a voltage of 12V.This voltage is used for charging a performance up to 15V.
When fully charged, the battery is usually not allocated excess gas, since the charge is up to 95%.Knowing how current charge car battery, it is important to choose the right method for the effective governing of the chargers.
- There is another method - a surge, which is used when the battery is charged to 95% and it is necessary to bring up to 100%.On the question of how the current to charge the battery in this case, the answer will be current, equal to the following calculation.Current is equal to 3% of the battery capacity.This not only achieved a 100% charge, and leveled the electrolyte density in all banks of batteries.
