BATTERY SYSTEM, SOC ESTIMATION METHOD FOR BATTERY SYSTEM, COMPUTER APPARATUS, AND MEDIUM

This disclosure provides a battery system, an SOC estimation method for the battery system, a computer apparatus, and a medium, the method comprising: mapping an upper limit and a lower limit of the state of charge of the second-system battery to a state of charge interval of the battery system, to establish a mapping relationship between the upper limit and the lower limit of the state of charge of the second-system battery and the state of charge interval of the battery system; and calculating the state of charge of the second-system battery and estimating a state of charge of the battery system according to the mapping relationship.
