Original Abstract Submitted

A battery state-of-charge estimation apparatus include: a memory, and a processor connected to the memory. Upon charging/discharging of a battery rack including multiple battery cells, the processor calculates a maximum SOC of a maximum-voltage cell and a minimum SOC of a minimum-voltage cell and calculates a representative SOC of the battery rack based on the maximum SOC and the minimum SOC. A corresponding battery state-of-charge estimation method is also disclosed.
