Design of the Equalizing Charge Circuit Based on Bidirectional Energy Transfer

Abstract:

The batteries in a battery pack may have different internal resistances, and this inconsistency may lead to fast aging of the whole pack. In order to overcome the shortcomings of existing equalizing charge method, a bidirectional energy transfer mechanism based battery equalizing charge schema is given. We detailed analysis the working principle of equalization circuit and equalization work process, and the program analysis and argument by experiments. Experiments show that the method structure is simple, and it can quickly realize the dynamic transfer of energy between the batteries. The battery power charging imbalance can be effectively solved.
