For the requirement of building up the battery management system of hybridelectric vehicle,the method of quick charge of batteries is investigatedunder the conditions of ensuring natural life of batteries. The characteristics of the general charge methods areanalyzed, and existing problems of these charge methods are discussed. In order to solve those problems, a new quick charge method for HEV batteries is proposed, which can shorten charge time under the variable-current condition of the battery pack,andcan sustain the state of charge (SOC) of batteries within the scope between 50% and 80%.
