A Modularized Cell to Cell Battery Balancing System

In this paper, a novel modularized cell to cell battery balancing system is proposed. Battery energy is able to be transferred from any cell to any other cell in the battery string. Moreover, the balancing system is modularized, which will further reduce the cost of the system. The balancing working principle is analyzed. The components of different balancing systems are analyzed and compared. The balancing circuit simulation is established to validate the proposed method. Simulation results show that the proposed method the modularized cell to cell balancing function is realized.
