САЖЕТАК / ABSTRACT:
The performance and safety of today’s electric vehicles (EVs) are significantly restricted by the operating temperature and corresponding temperature gradients of the lithium-ion (li-ion) battery. The phase change material (PCM)-based battery thermal management (BTM), makes full use of the PCM phase change to absorb battery heat, however, will exacerbate heat accumulation within the battery when the room temperature elevates to a large value. In this article, a BTM scheme integrating PCM and external metal fin structures is proposed, which takes advantage of air forced convection through fins for cooling purpose when the PCM melts. A series of battery discharging experiments were conduct to examine effectiveness of this BTM scheme and different fin structures. The results show the BTM scheme coupled with rectangular fins with grooves well caters for thermal demands of Li-ion battery in scorching environment. The proposed BTM scheme is a simple and useful cooling solution for Li-ion battery working under different thermal circumstances.
