A new charging mode of Li-ion batteries with LiFePO4C under low temperature

In order toimprove the low temperature performance of LiFePO4/Cpower batteries, the charge–discharge characteristics werestudied at different temperatures, and a new charging modeunder low temperature was proposed. In the new chargingmode, the batteries were excited by current pulses with thecharge rates between 0.75 C and 2 C, while the dischargerates between 3 and 4 C before t..
