Abstract
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.
Claims11
A battery state-of-charge estimation apparatus, comprising:
- a memory;
- and
- a processor connected to the memory,
- wherein, upon charging/discharging a battery rack comprising multiple battery cells, the processor calculates a maximum state of charge (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 battery state-of-charge estimation method comprising, upon charging/discharging a battery rack comprising multiple battery cells:
- receiving, by a processor, measurement data of each of the battery cells from a sensor;
- calculating, by the processor, a maximum SOC of a maximum-voltage cell and a minimum SOC of a minimum-voltage cell based on the measurement data of each of the battery cells;
- and
- calculating, by the processor, a representative SOC of the battery rack based on the maximum SOC and the minimum SOC.
