Abstract

In order to balance the capacity and energy difference of single battery in the battery pack, improve the energy utilization of the battery pack, and use the equalization circuit in the charge and discharge process of the battery pack. The energy dissipative circuit is balanced by shunting through the parallel resistance of single cells. The energy dissipative circuit structure of non energy dissipative circuit is relatively complex, which can be divided into energy conversion equalization and energy transfer equalization. Designing a simple and efficient voltage detection circuit is a problem that needs to be solved in the equalization circuit.
