The invention discloses a cooling control method of an electric automobile, a cooling assembly and the automobile. The method comprises the steps that whether a power battery meets a cooling starting condition or not is judged according to the environment temperature and battery state information; if the power battery meets the cooling starting condition, controlling a cooling assembly to operate to enable the power battery to enter a cooling mode; dynamically adjusting the cooling strategy of the cooling assembly according to the change of the battery state information in the cooling mode; and if the power battery meets the cooling stop condition, controlling the cooling assembly to operate to enable the power battery to exit the cooling mode. Whether cooling needs to be started or not is comprehensively judged through the environment temperature and the battery state information, and the cooling strategy is dynamically adjusted through the battery state change after cooling is started, so that early starting and accurate regulation and control of power battery cooling are achieved, rapid temperature rise of the power battery is avoided, the charging efficiency is improved, and the service life of the battery is prolonged.
本发明公开了一种电动汽车的冷却控制方法、冷却组件及汽车,其中方法包括:根据环境温度和电池状态信息判断动力电池是否满足冷却开启条件;如果动力电池满足冷却开启条件,则控制冷却组件运作使动力电池进入冷却模式;在冷却模式下根据电池状态信息的变化动态调整冷却组件的冷却策略;如果动力电池满足冷却停止条件,则控制冷却组件运作使动力电池退出冷却模式。本发明通过环境温度和电池状态信息综合判断是否需要开启冷却,并在冷却开启后通过电池状态变化动态调整冷却策略,以实现动力电池冷却的提前开启及精准调控,避免动力电池温度急剧上升,以加快充电效率并延长电池寿命。
