蓄电池主动式在线电压自动均衡及除硫技术的研究

Techniques of active online automatic voltage equalization and sulfur removal for battery

本文提出的均衡技术采用间隙式优先充电的双闭环控制模式,内部采用光MOS开关阵列,利用开关电源技术,以能量转移方式将高电压电池的电量转移到低电压电池,电量转移是双向并行进行,从而达到电池电压均衡。研究成果可为蓄电池的有效利用提供参考。

The dual-closed loop control mode for the interval priority charging is adopted for the voltage equalization technique proposed herein,for which the optical MOS switch array is used inside,and then the power is transferred from high-voltage battery to low-voltage battery with the mode of energy transfer by means of the switching power technique,while the power transfer is made with the two-way parallel mode,thus the battery voltage equalization is achieved.The study result can provide a reference for the effective utilization of battery.
