Design and Practice of A Heterogeneous Compatible Energy Storage Power Station By Secondary Utilization of Retired EV Battery

This paper introduces a heterogeneous compatible energy storage power station by secondary utilization of retired EV battery and expounds sub-circuit control concept of retired batteries with different types,structures and period. The whole application of the retired EV battery packages is realized by a "communication bridge". Then, the charging and discharging power of each circuit is coordinated by a "heterogeneous compatible controller" to balance the charging and discharging power of entire energy storage system. According to the operation data analysis of the power station, it is proved that heterogeneous compatible energy storage power station based on the retired EV batteries with different types, structures and periods have the application feasibility and economy.
