Experimental assessment on the thermal control performance of composite phase change material for fast charging power module

Towards intelligent electric vehicle power batteries and multi-scenario application vehicle operation safety charging strategies: a review

“…High-current charging generates considerable heat, and when the battery temperature increases above a certain point, the thermal runaway reaction takes place, which can result in dangerous mishaps. 1,2 In addition to triggering battery safety issues, high-current charging can also lead to battery health degradation issues, mainly triggering a side reaction of lithium precipitation from the negative electrode. 3,4 Lithium ions are primarily inserted into the positive and negative electrodes to charge lithium-ion batteries, and a reasonable choice of charging control strategy can reduce battery polarization, maintain the dynamic balance of charging within the battery, prevent the phenomenon of overcharging, and ensure the safe use of the battery.…”
