摘　　要：目前纯电动汽车的热源由动力电池提供,热能消耗将直接影响纯电动车的续驶里程。为了提升汽车的续驶里程,采用Fluent软件模拟计算与实车环境模拟风洞验证试验相结合的方法,对除霜典型加热工况等进行研究。在FMVSS103除霜工况下,采用液侧电加热器,加热期间总电能消耗接近1.736 k W·h,而电热前挡风玻璃总电能消耗接近0.156 k W·h,几乎只是液侧加热能量消耗的9%。整车及空调系统能量分配计算结果显示,采用电热前挡风玻璃加热可大幅减少电能消耗,提高汽车续驶里程。Nowadays, the heat source of the electric vehicle is provided by battery,the heating consumption will directly affect the cruising range of electric vehicle. In order to extend the cruising range, the typical heating for defrosting was studied by using Fluent to simulate combined with environmental tunnel test of the actual vehicle. In the defrosting condition that is stipulated in FMVSSI03, the total electric power consumption was close to 1.736 kW·h using the electric heater that is located in the liquid side. The total electric power consumption nearly reached to 0.156 kW ·h under the condition of electrically heating the front windscreen, its total electrical power consumption is only 9% compared with the consumption that is consumed using the side electric heater. The energy distribution of vehicle and air conditioning system shows that electrically heating the front windscreen can greatly reduce the electric power consumption and extend the cruising range.
