摘要:One disadvantage of current equalization circuit, used in series-connected lithium-ion batteries, is high energy transfer-loss. It inevitably leads insecurity of equipment and cooling investment increased. In this paper, a novel modularized equalization circuit, based on DC-DC chopper, is proposed to supply zero lossin theory. The researched modularized circuit includes double battery cells, two switches and an inductor. A respected output voltage can be satisfied through multiple modules connected in series. To confirm its performance, theoretical analysis and control method have been finished, respectively. Simulation and small scale experiments are applied to verify the effect of energy equalization in this work.
