The battery consistency in the series-first and parallel-first topology modules exhibited significant differences and some regularity. Abstract The thermal effect of lithium (Li)-ion batteries affects its performance and service life and threatens its safety.
To verify the proposed battery pack consistency modeling method and its application on a battery pack EUE estimation, a retired LiFePO 4 lithium-ion battery is tested. The battery pack had been used in a pure electric passenger vehicle for …
Firstly, the consistency among battery cells always tends to be worse with battery pack aging so that it is the worst when a battery pack is retired (Zhou et al., 2017). Like the wooden barrel theory that the cubage of a barrel is dependent on the shortest wood plate, the worst battery cell lowers the performance of the whole battery pack in …
