| Abstract: | Based on analyzing the reason of storage battery dissimilarity,a practical and efficient balance charging system is designed to solve the problem.When a group of batteries is being charged,a controllable PWM circuit constituting an equilibrium module is working to shunt the charging current and to monitor its work condition for each battery.The independent equilibrium module can effectively realize balance charging for every battery,and overcome dissimilarity among all batteries.This method can significantly extend storage battery lifetime.Experiments verify the feasibility of the balance charging system for series-connected batteries. |
