电动汽车动力电池均衡系统的设计和试验
Design and test study on balance system of electric vehicle power battery
摘要
Abstract
Due to the difference of initial performance of single battery and the enlargement of the difference in use process,the advantages of active equalization and disadvantages of passive equalization were taken into account.A new type vehicle power battery balance system,which combined of inter-cell active balanced circuit and battery peak passive balanced circuit,was presented.The system took the single cell terminal voltage and the voltage of the battery pack as the control target,compared the ε value of the battery pack and the δ value of the battery pack with the value of threshold to control the the opening and closing of field effect transistor and bipolar junction transistor to realize the active balance and passive balance.The experiment results show that equalization system in two states of charging,discharge can play a balanced effect.The validity of the equilibrium system was illustrated and the purpose of design was achieved.关键词
