摘要
通过常温和高温工况下不同放电倍率(1C、3C、5C)的放电,测试电池模块内的温度变化和电池组电压变化,对比半导体制冷(Thermo Electric Cooling,简称TEC)与强制风冷两种冷却方式对动力电池组散热的影响。结果表明,随着放电倍率增加,相比风冷电池模块,TEC电池模块的散热优势越来越明显。同时,TEC模块在放电结束后可以迅速降温,降温速率快且呈线性降低,5C放电后的降温速率为0.03℃/s,这一优势对电池充放电循环有较大帮助。高温工况对半导体制冷电池模块的温控性能影响也不大。
The changes of temperature and voltage were tested by the under room and high temperature at different discharge rates（1C, 3C, 5C）, the influences of TEC module and air-cooling module on heat dissipation power battery were compared and analyzed. It indicated that compared with air-cooled battery module, the battery module TEC cooling have more advantage as the discharge rate increases. At the same time, TEC module cools down rapidly after discharge, the cooling rate is 0.03 ℃/s after discharge at 5C. This advantage was conducive to the battery charge and discharge. High temperature conditions impact on the performance of TEC battery module temperature is not so great.
