【摘要】：市场上的封装电池是由几个具有相同特性的电池单元串联而构成的,因此蓄电池充电器只能对封装电池整体进行控制,无法避免内部单元的过充电,从而降低了蓄电池使用寿命。提出一个对电池最小单元进行最优化控制的充放电控制拓扑,并进行软开关参数设计和整合,对变脉宽脉冲充电方法进行改进,设计了一种简单有效的正负脉冲充电方法,可有效消除充电过程中的极化现象,实现快速充电的同时提高了电池寿命。此外,对提出的拓扑和充电策略设计了便捷可行的均衡方案。最后制作实验样机,验证了拓扑的实用性、控制的有效性以及整体方案的可行性。
[Abstract]:The packaging battery in the market is made up of several battery units with the same characteristics in series, so the battery charger can only control the package battery as a whole and can not avoid overcharging of the internal unit. Thus, the service life of battery is reduced. A charge-discharge control topology with optimal control for the minimum cell of the battery is proposed, and the parameters of soft switch are designed and integrated. The method of pulse charging with variable pulse width is improved, and a simple and effective positive and negative pulse charging method is designed. It can effectively eliminate the polarization phenomenon in charging process, realize fast charging and improve battery life. In addition, a convenient and feasible equalization scheme is designed for the proposed topology and charging strategy. Finally, an experimental prototype is made to verify the practicability of topology, the effectiveness of control and the feasibility of the overall scheme.
