摘要
基于帕尔贴效应提出一种通过热电装置(Thermoelectric Device,TED)实时控制电池温度的方法.该方法集TED的制冷与加热功能于一体,控温效果良好,可以满足电池模组热管理需求.电池模组由3×5排列的圆柱电池组成,填充泡沫金属复合相变材料,热电装置布置在电池模组外壳正对大面处.与液冷试验相比,热电制冷可以在1~5 W单电池产热功率下显著降低电池模组的温度,将模组温差控制在5℃内.温控试验进一步表明,采用温控器实时控制的TED可以有效稳定模组温度,将温度波动控制在2~3℃.此外,建立一维热阻网络,基于稳态理论对TED热性能分析.结果表明,在制冷工况下,TED的冷端温度随其电流的增大呈先减后增的趋势,热端温度与TED电流成正比.
Based on the Peltier effect,a method of real-time controlling battery temperature through thermoelectric device(TED)was proposed.It integrated the refrigeration and heating functions of TED,has a good temperature control effect,and can meet the thermal management needs of battery modules.The battery module consists of 3×5 rows of cylindrical batteries filled with foam metal composite phase change materials,and the thermoelectric device was arranged on the large face of the battery module shell.Compared with the liquid cooling experiment,thermoelectric refrigeration could significantly reduce the temperature of the battery module at 1~5 W of single cell heat generation power,and control the temperature difference of the module within 5℃.The temperature control experiment further shows that the TED controlled by the thermostat in real-time can effectively stabilize the module temperature and control the temperature fluctuation within 2~3℃.In addition,a one-dimensional thermal resistance network was established,and the thermal performance of TED was analyzed based on steady-state theory.The result shows that under the refrigeration condition,the cold junction temperature of TED is decreasing first and then increasing with increasing of its current,and the hot junction temperature is proportional to the TED current.
