Abstract

The invention discloses a SOC balancing control method among battery box systems, which comprises the following steps: obtaining SOCi corresponding to the ith battery box system, wherein, 1 <= i <= M,M is the number of battery box systems; When the received power control instruction is not full power instruction, the inter-box power equalization strategy is executed according to the SOCi, so thatthe SOC values of the M battery box systems are equalized. The invention automatically implements the inter-box power balance strategy according to the SOC value, thereby improving both the balance effect and the balance automatic performance.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to an SOC balance control method among battery box systems. Background technique [0002] The existing AGC frequency modulation energy storage system includes multiple battery box systems, each battery box system includes multiple battery stacks, each battery stack has an independent battery management system BMS, due to the battery internal resistance of each battery stack , Inconsistencies in self-discharge capacity, differences in operating temperature ranges, etc. Therefore, after the AGC frequency modulation energy storage system has been in operation for a long time, the SOC values ​​​​of different battery box systems will vary. [0003] In view of this, it is necessary to provide an SOC balance control method that can ensure the balance of SOC values ​​among the battery box systems. Contents of the invention [0004] The purpose of the present invention is to provi...
