The invention provides a discharge cooling control method of an electric mine truck, a thermal management system and the electric mine truck. The method comprises the following steps: when a battery system is in a discharge state, acquiring a current value of discharge current of the battery system; when the current value is larger than a preset current value, the rotating speed of the first water pump is controlled according to the current value, so that the flow speed of the cooling liquid in the large circulation loop changes along with the current value till the current value is smaller than or equal to the preset current value; and when the current value is smaller than or equal to the preset current value, the rotating speed of the second water pump is controlled according to the current value, so that the flow speed of the cooling liquid in the small circulation loop changes along with the current value till the current value is larger than the preset current value. The working reliability of the electric mine truck can be improved.

    本申请提供一种电动矿卡的放电冷却控制方法、热管理系统及电动矿卡。该方法包括:在电池系统处于放电状态时,获取电池系统的放电电流的电流值;在电流值大于预设电流值时,根据电流值控制第一水泵的转速,以使大循环回路中的冷却液的流速跟随电流值变化,直至电流值小于或者等于预设电流值;在电流值小于或者等于预设电流值时,根据电流值控制第二水泵的转速,以使小循环回路中的冷却液的流速跟随电流值变化,直至电流值大于预设电流值。本申请能够提高电动矿卡的工作可靠性。
