Popis:	The capacity loss of the high power LiFePO4 -graphite (LFP-C) Li-ion batteries under four common different charging modes was investigated. First, the battery model coupled equivalent circuit, thermal and aging model was established. Then the validity of the battery model was verified by the experimental data. Finally, four common different charging strategies were given to simulate the capacity loss of the batteries. The simulation results showed that the recharge took place in the morning before the driver went to work and then underwent four electric vehicle NEDC cycles always had the minimal capacity loss, and that the recharge took place whenever the driver had time always had the maximum capacity loss.
