Lithium battery pack charging factor
By analyzing the CC-CV charging results for LiFePO4 and ternary system batteries under different charging currents and cutoff voltages, it is observed that: (1) With a fixed cutoff voltage, increasing the charging current and decreasing the constant current ratio shortens the charging time but increases energy consumption; (2) With a fixed charging current, lowering the cutoff voltage reduces the constant current charge ratio, resulting in lower charge capacity and energy.
