摘要
为了提高燃料电池汽车在低温环境下的采暖性能,对燃料电池汽车低温冷启动过程进行了梳理,分析了热泵采暖系统和PTC采暖系统的原理以及优缺点,并以一款燃料电池公交车为例,利用实车测试的方法分析了PTC采暖系统在燃料电池汽车中的应用。研究结果表明,PTC采暖是目前最适用于低温环境下的汽车采暖方式,燃料电池公交车由于车内空间较大,温度升高的速率较慢。热泵采暖系统具有更高的能量利用效率,燃料电池热管理方案对于改善续驶里程很重要,强化采暖系统与车内空间的换热提升车内升温速度。
In order to improve the heating performance of fuel cell vehicles in low temperature environment, this paper analyzed the cold start process of fuel cell vehicles at low temperature, and analyzed the principle, advantages and disadvantages of heat pump heating system and Positive Temperature Coefficient(PTC) heating system. Taking a fuel cell bus as an example, the application of PTC heating system in a fuel cell vehicle is analyzed by means of real vehicle test.The research results show that PTC heating is the most suitable vehicle heating method in low temperature environment,fuel cell bus due to the large interior space, the temperature rise rate is slow, and specific suggestions are given for the current vehicle heating scheme. The heat pump heating system has higher energy utilization efficiency, the fuel cell thermal management scheme is very important to improve the driving range, strengthen the heat exchange between the heating system and the interior space to improve the interior heating speed.
