Current distribution method and analog circuit

Abstract

The present disclosure provides a current distribution method and an analog circuit. The method includes: determining, according to a total quantity of battery clusters of a plurality of battery clusters connected in parallel in a battery energy storage system, a distribution proportion constraint interval set for each battery cluster; determining, according to a battery-cluster parameter, a current distribution target proportion set for each battery cluster, where the current distribution target proportion is within the distribution proportion constraint interval, and the battery-cluster parameter includes at least one of the following: a present remaining capacity of the battery cluster, a capacity set critical value and the distribution proportion constraint interval; and distributing current to various battery clusters according to the current distribution target proportion. The present disclosure can ensure battery clusters with different capacities to quickly reach balance during operation, thus achieving an effect of improving stability and reliability of the battery energy storage system.
