Experimental investigation on the effect of phase change materials for thermal management improvement of the fast charging power module

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

“…Highcurrent 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, highcurrent 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.…”

Experimental Investigation on the Thermal Management for Lithium-Ion Batteries Based on the Novel Flame Retardant Composite Phase Change Materials

“…PCM offers the benefits of large thermal energy storage capacity and zero energy consumption since it does not produce temperature change during the phase change process, with strong thermal management capability and high efficiency [14]. Liu et al [15] investigated the effect of different heat generation powers, air cooling airflow rates, melting point, thermal conductivity, and filling thickness of PCM on the thermal management of fast charging modules and recommended the use of PCM with a suitable melting point and a high thermal conductivity. However, the limited thermal conductivity of PCM materials is an inherent disadvantage.…”
