The invention discloses an air conditioner fresh air preheating system, an electric automobile and a preheating method, whichbelong to the technical field of electric automobiles. The preheating system comprises a radiator and an air duct pipe, the radiator is communicated with an electric appliance element set and a battery set of the electric automobile to form an annular loop, and the air ductpipe is used for introducing fresh air subjected to heat exchange with the radiator into an air inlet of an air conditioner. The preheating system can collect waste heat generated by the electric appliance element set and the battery set to heat fresh air and introduce the heated fresh air into the air conditioner. Due to the fact that the fresh air has a certain temperature, the air conditioner uses the fresh air with the certain temperature, the electric quantity consumed for heating the air conditioner to the preset temperature can be reduced, and the cruising ability of the electric automobile is improved.

    本发明公开了一种空调新风的预加热系统、电动汽车及预加热方法,属于电动汽车技术领域。本发明所提供的预加热系统包括散热器和风道管,散热器与电动汽车的电器元件组以及电池组均连通并分别形成环形回路,风道管用于将与散热器进行热交换后的新风引入空调进风口内。该预加热系统能够将电器元件组和电池组产生的废热收集起来以加热新风,并将加热后的新风引入空调内。由于新风已经具有一定温度,空调使用具有一定温度的新风能够降低空调制热至预设温度所需消耗的电量,有利于提高电动汽车的续航能力。
