Abstract: The research object is the retired power battery used in the energy storage system. A safety assessment method for cascade utilization of battery combination is proposed. This method uses multi-dimensional data such as battery manufacturers, types, and tests for cascade utilization, and develops comprehensive evaluation and example analysis on the safety performance of cascade secondary batteries by entropy weight-TOPSIS method and analytic hierarchy process. The research results show that, this method can effectively evaluate the safety of the secondary batteries for the energy storage system to be constructed with different manufacturers, batches, and types of retired power batteries, and it is helpful to select the secondary batteries with higher safety to construct the energy storage system. It can further improve the safety of the system and meet the practical needs of large-scale promotion and construction of cascade utilization of energy storage systems.

Key words: retired power batteries, reuse, risk management, energy storage, safety technology, TOPSIS
