Title:
METHOD FOR BALANCING SOCS OF MULTIPLE BATTERIES IN CHARGING FACILITY
Document Type and Number:
WIPO Patent Application WO/2018/133362
Kind Code:
A1
Abstract:
Provided is a method for balancing SOCs of multiple batteries in a charging facility. Multiple batteries are used to simultaneously charge the same electric vehicle. The method comprises the following steps: acquiring an SOC of each of multiple batteries (S1); performing comparison on the acquired SOCs of the respective batteries (S2); and determining, according to a comparison result, power levels of the respective batteries used to charge an electric vehicle. In the present invention, balancing of SOCs of multiple batteries in a charging facility is performed to address an issue in which power of a battery having a low SOC is exhausted while power of a battery having a high SOC remains sufficient, such that a subsequent electric vehicle can still be charged by multiple batteries at the same time, thereby improving service quality. The present invention also ensures a consistent number of times of charging and discharging of the multiple batteries, thereby balancing SOCs of batteries, and extending service life of the batteries.
