The invention discloses a vehicle, a thermal management control method and device thereof and a storage medium. The thermal management control method of the vehicle comprises the steps that the state of the whole vehicle is determined, and the temperature of a power battery is obtained; determining the cooling grade of the power battery according to the whole vehicle state and the power battery temperature; determining the cooling priority between the cab and the power battery according to the cooling grade; and controlling a cooler valve of the power battery cooling subsystem and an evaporator valve of the cab air conditioning subsystem according to the cooling priority. Therefore, according to the thermal management control method of the vehicle, by obtaining the state of the whole vehicle and the temperature of the power battery, the cooling priority between the cab and the power battery is judged, and then different control valve opening schemes are output through the air conditioner refrigeration system, so that the performance such as temperature balance and charging and discharging power of the battery is improved; meanwhile, the requirement for comfort of the cab under different working conditions is met, and the use experience of a user is greatly improved.
本发明公开了一种车辆及其热管理控制方法、装置及存储介质。其中,车辆的热管理控制方法包括:确定整车状态,并获取动力电池温度;根据整车状态和动力电池温度确定动力电池的冷却等级;根据冷却等级确定驾驶室与动力电池之间的冷却优先级;根据冷却优先级对动力电池冷却子系统的冷却器阀和驾驶室空调子系统的蒸发器阀进行控制。由此,该车辆的热管理控制方法通过获取整车状态和动力电池温度,对驾驶室与动力电池之间的冷却优先级进行判断,然后通过空调制冷系统输出不同的控制阀开启方案,提高了电池的温度平衡和充放电功率等性能,同时满足不同工况下的驾驶室舒适性的要求,大大提高了用户的使用体验。
