Abstract :
This paper describes an algorithm for managing a system consisting of “dissimilar” battery packs in parallel without multiple DC/DC converters interfacing each battery pack to the load. The power loss from the circulating current can be avoided so that the operating time of the parallel battery system is prolonged. The proposed algorithm is able to recognize the load demand and determine the number and sequence of the battery packs needed to be connected to the DC bus.
