The invention discloses a temperature control method and system of an electric automobile and the electric automobile. The temperature control method of the electric automobile comprises the steps ofobtaining the average current of a battery module within a first preset duration, wherein the first preset duration is the duration from the moment when the electric automobile stops running to the moment when an electric automobile control system is powered off; determining the current temperature of the battery module according to the average current of the battery module within the first presetduration; according to the current temperature and the target cooling temperature of the battery module, determining a second preset duration which is the cooling duration of the battery module; andaccording to the second preset duration, cooling the battery module for the second preset duration, and then cutting off the power supply signal of a battery module cooling module. According to the technical scheme provided by the embodiment of the invention, after the electric automobile stops running, the cooling time of the battery module is prolonged.
本发明公开了一种电动汽车的温度控制方法、系统以及电动汽车。该电动汽车的温度控制方法包括:获取电池模组在第一预设时长内的平均电流,其中,第一预设时长为电动汽车从停止运行对应的时刻到电动汽车控制系统下电时刻之间的时长;根据电池模组的第一预设时长内的平均电流,确定电池模组的当前温度;根据电池模组的当前温度和目标冷却温度,确定第二预设时长,其中,第二预设时长为电池模组的冷却时长;根据第二预设时长,对电池模组进行冷却第二预设时长后,切断电池模组冷却模块的电源信号。本发明实施例提供的技术方案,在电动汽车停止运行后,延长了对电池模组的冷却时间。
