摘要
为提高串联电池组充电过程中的一致性,提出了一种简易高效的均衡控制系统.在此系统中,通过DC-DC转换器利用PWM均衡所有电池单元电压.通过软开关电感补偿的方法可以减小转换时的浪涌和噪声.此系统适用于电动汽车、便携式个人电脑、UPS等.
For balancing battery cells connected in series string, a simple and high performance battery balancing system is proposed. In this system, technique of DC to DC converter withPWM control is used for balancing all cell voltages completely. The switching surge and noise are made small by soft switching with inductor commutation. This system is suitable for electric vehicle, handy -type personal computer, UPS and so on.
