6 FAQs about [High current charging for batteries]
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 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 types of batteries can be charged using MCC Method?
The MCC method is suitable for charging the following battery types: lead-acid, NiMH, and Li-ion batteries. With equal initial current values, the MCC charging process takes a bit more time compared to the CC-CV charging method.
What happens if you charge a lithium ion battery too fast?
Traditional fast charging methods usually entail charging the battery with high currents. Nonetheless, prolonged high-current constant charging can cause a progressive rise in battery temperatures. Excessive temperature can shorten the lifespan of LIBs, leading to decreased battery performance and driving range .
