摘要：【中文】本发明公开了一种锂离子动力电池组充放电主动均衡方法，属于电池充放电领域。首先构建电压均衡电路，连接电池单体选择电路，可充电蓄电池和单体电池形成完整的主动均衡电路。然后电压采集模块并联在主动均衡电路的两端，设定均衡电压上限和下限。电压采集模块实时采集各电池单体的电压，如果电池单体h的电压高于上限值或低于下限值，进行均衡充电或放电模式，并设定充电和放电的方向。针对选中的电池单体h，按照设定对电池单体h进行均衡充电或放电。最后通过控制主动均衡电路中的MOS管产生频率不同的激励，形成恒压或恒流，使得动力电池单体或蓄电池快速高效的完成均衡，直至充电完成。本发明能够延长锂离子电池的使用寿命。 【EN】The invention discloses a lithium ion power battery pack charge and discharge active equalization method, and belongs to the field of battery charge and discharge. Firstly, a voltage balancing circuit is constructed and connected with a single battery selection circuit, and a rechargeable storage battery and a single battery form a complete active balancing circuit. And then the voltage acquisition module is connected in parallel at two ends of the active equalization circuit to set the upper limit and the lower limit of the equalization voltage. The voltage acquisition module acquires the voltage of each battery monomer in real time, and if the voltage of the battery monomer h is higher than an upper limit value or lower than a lower limit value, a balanced charging or discharging mode is carried out, and the charging and discharging directions are set. And aiming at the selected battery monomer h, carrying out equalizing charge or discharge on the battery monomer h according to the setting. And finally, controlling MOS (metal oxide semiconductor) tubes in the active equalization circuit to generate excitation with different frequencies to form constant voltage or constant current, so that the power battery monomer or the storage battery can quickly and efficiently finish equalization until charging is finished. The invention can prolong the service life of the lithium ion battery.
