电动城市客车冷却系统计算与测试

Calculation and Test on Cooling System of an Electric City Bus

以一纯电动客车为例,根据其电机及控制器在高速行驶工况的下热损耗功率,计算其冷却系统有关参数,并对样车进行冷却能力测试。为电动客车冷却系统设计及改进提供参考。

Taking a pure electric bus as an example,the authors calculate the relative parameters of the cooling system and test the cooling capacity of the prototype vehicle according to the heat loss power of the motor and controller under the condition of high speed running. This can provide a reference for the design and improvement of electric bus cooling system.
