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.

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.

What is the difference between pre-charging and constant current charging?

Pre-charging is when the battery is initially plugged in and is drawing a very small amount of current in order to get the chemical reaction started within the battery. Constant current charging is when the majority of the charge is applied to the battery.

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 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.

What happens if a battery is overcharged?

Excessive Current and Potential Hazards Overvoltage charging, a scenario where the charging voltage exceeds the battery’s designed limit, can lead to an influx of excessive current. This surge not only poses a risk of physical damage to the battery but also increases the likelihood of catastrophic failures, including explosions.
