What amount of current should I use to charge a 12V car battery?

There is a rumor unspoken rule : the slower charge the better battery, it seems charging current is around C/10 and <= 10A is more favourable to prolong lead acid battery. However, better read the battery specs and datasheet to find out. Example: Your battery capacity is 80Ah, C/10=8A <= 10A, then maximum charging current is 8A.

Reasons Why a Car Battery Voltage Is Too High

My 2015 Acadia with 40,000 km.has a battery voltage of 12.6 when started, with the voltage rising to 15 to 15.5 after a few minutes. In summer, this voltage stays in the 15V region as I drive for perhaps up to an hour or more, but in fall or winter it soon drops to 12.6 to 13.5 volts over the first few minutes of driving and stays there.

6 FAQs about [Charging battery with high current and high voltage]

What is a high charge current?

A high current value is required to provide a constant terminal voltage at anearly stage of the charging process. A high charging current from 15 percent to 80 percent SOC provides fast charging, butthe high current stresses the battery and can cause battery lattice collapse and pole breaking.

What is battery charging?

Charging is the process of replenishing the battery energy in a controlled manner. To charge a battery, a DC power source with a voltage higher than the battery, along with a current regulation mechanism, is required. To ensure the efficient and safe charging of batteries, it is crucial to understand the various charging modes.

What is a good charge voltage for a battery?

A high charging current from 15 percent to 80 percent SOC provides fast charging, butthe high current stresses the battery and can cause battery lattice collapse and pole breaking. The main challenge for CV charging is selecting a proper voltage value that will balance the charging speed, electrolyte decomposition, and capacity utilization.

Why do EV batteries need a high charging current?

A high charging current provides a quick charge but also significantly affects the battery’s aging process. A low charging current provides high capacity utilization but also produces a very slow charge, which is inconvenient for EV applications. Another method is CV charging, which regulates a predefined constant voltage to charge batteries.

Is CV charging a good way to charge a battery?

Generally, the CV charging method is efficient for speedy charging, but it damages the battery capacity. The negative effect is caused by an increased charging current at a low battery SOC (at the beginning of the charging process), where the current value is significantly higher than the nominal battery current.

What are battery charging modes?

Understanding The Battery Charging Modes: Constant Current and Constant Voltage Modes Charging is the process of replenishing the battery energy in a controlled manner. To charge a battery, a DC power source with a voltage higher than the battery, along with a current regulation mechanism, is required.
