BATTERY CONTROL SYSTEM AND BATTERY CONTROL METHOD

原文（中国語）

A battery control system includes an upper-level control unit and a lower-level control unit. The upper-level control unit includes a battery information acquisition unit, a vehicle information acquisition unit, a threshold value setting unit that sets a threshold value defining a charge amount of a second battery based on battery information, and a chargeability determination unit that determines whether the second battery can be charged based on vehicle information and transfers a determination result and the threshold value to the lower-level control unit. The lower-level control unit includes a charge amount monitoring unit that monitors the charge amount of the second battery, and a charging necessity determination unit that transfers a charge request for the second battery to the upper-level control unit when the determination result indicates that the second battery can be charged and the charge amount is equal to or lower than the threshold value.
