Battery power system with arrayed battery power modules

Abstract

A battery power system configured by arrayed battery power modules (BPMs) is presented. Each BPM consists of a battery pack equipped with an associated bi-directional power electronic converter for charging and discharging. The number of BPMs in the array is schemed to cope with the required output voltage, current, power as well as sustainable energy. All BPMs in the configuration are mutually interactive to each other and have to be operated collaboratively with the others, but allowed to be controlled individually, facilitating the maintenance, protection, and the management of the battery power system.
