| Abstract: | In order to use the parameter identification technology to sort the retired batteries and realize thesecondary utilization of batteries, the performance of the retired power battery such as residual capacity, residual life, SOC, SOH and others are identified by appropriate technical method. The performance of retired batteries under the current state is evaluated according to the relevant data obtained, which provides theoretical basis for parameter identification of secondary utilization of power batteries. |
