The invention relates to the technical field of power batteries, in particular to a thermal management method and device of a power battery, a vehicle and a storage medium, and the method comprises the following steps: detecting the current charge state and the current temperature of the power battery during charging; according to the current state of charge and the current temperature, predicting the total charging duration and the temperature rise curve of the power battery, and according to the temperature rise curve, calculating the total thermal management duration of the power battery; and calculating a thermal management starting moment according to the charging total duration, the thermal management total duration and the current moment, and starting a thermal management system of the power battery when the current moment reaches the starting moment. Therefore, the problems that in the prior art, heat dissipation of the power battery is guaranteed through a heat management system with higher refrigeration power, and the cost of the whole vehicle is increased are solved.

    本申请涉及动力电池技术领域,特别涉及一种动力电池的热管理方法、装置、车辆及存储介质,其中,方法包括:检测动力电池充电时的当前荷电状态和当前温度;根据当前荷电状态和当前温度预测动力电池的充电总时长和温升曲线,根据温升曲线计算动力电池的热管理总时长;根据充电总时长、热管理总时长和当前时刻计算热管理启动时刻,并在当前时刻达到启动时刻时启动动力电池的热管理系统。由此,解决了相关技术中通常通过制冷功率更大的热管理系统保证动力电池的散热,增加整车成本等问题。
