Title:
BATTERY TARGET SOC DETERMINING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/120771
Kind Code:
A1
Abstract:
A battery target SOC determining method and device. The method comprises the following steps: when current flows through a battery, collecting the electric quantity of each sampling point of the battery (S101); then determining the current state of the battery according to the electric quantity of each sampling point of the battery (S102); selecting a target correspondence from at least two correspondences between a specified SOC and voltages according to the current state of the battery (S103); and determining a target SOC according to the target correspondence (S104). The method can solve the problem in the art of low accuracy of target SOC which is obtained based on correspondences between a nominal SOC and voltages under a static condition.
