The invention discloses an electric vehicle, a thermal management control method and device thereof and a storage medium. The thermal management control method of the electric vehicle comprises the steps that power battery information of the electric vehicle and the remaining available power of the whole vehicle are obtained, the cab temperature of the electric vehicle is obtained, and the power battery information comprises the power battery temperature and the power battery electric quantity; when it is determined that the discharging capacity of the power battery meets the preset requirement according to the remaining available power of the whole vehicle and the electric quantity of the power battery, limited power control is conducted on a PTC heater of the electric vehicle, and the heating power of the PTC heater is distributed according to the cab temperature and the power battery temperature. Therefore, according to the thermal management control method of the electric vehicle, the heating power of the PTC heater is distributed according to the cab temperature and the power battery temperature, it is guaranteed that the power battery can be normally driven and charged in a low-temperature environment, the cab temperature is not too low, and the driving safety of the electric vehicle and the use experience of a user are improved.

    本发明公开了一种电动车辆及其热管理控制方法、装置及存储介质。其中,电动车辆的热管理控制方法包括:获取电动车辆的动力电池信息和整车剩余可用功率,并获取电动车辆的驾驶室温度,其中,动力电池信息包括动力电池温度和动力电池电量;在根据整车剩余可用功率和动力电池电量确定动力电池放电能力满足预设要求时,对电动车辆的PTC加热器进行限功率控制,并根据驾驶室温度和动力电池温度对PTC加热器的加热功率进行分配。由此,该电动车辆的热管理控制方法根据驾驶室温度和动力电池温度对PTC加热器的加热功率进行分配,保证动力电池在低温环境下能够正常行车充电以及驾驶室温度不会过低,提高电动车辆的行驶安全性以及用户的使用体验。
