| Popis: | In order to improve the equalization control efficiency of the battery charge equalization system, this paper applies the double closed-loop controller to the battery charge automatic equalization system. First, the overall block diagram of the hardware circuit of the charging system is designed, and the switching control of charging and discharging is completed by using TMS320F2812 chip. Secondly, the optimal charging current is calculated according to Mars law. Then, a double closed-loop controller is introduced to balance the battery charge, and the charge balance equation is constructed and solved. Finally, the adjusted parameters are obtained to realize the automatic charging equalization control. The experimental results show that the equalization control time of this method is always within 25s, which indicates that its charge equalization control effect is good. |
