The invention discloses a power battery heating control method, a storage medium, a range extending system and a heavy truck. The power battery heating control method comprises the steps that it is determined that a vehicle meets the parking heating condition; and the vehicle is controlled to enter an in-situ warming-up mode, and in the in-situ warming-up mode, the range extender is controlled to operate at an idle speed so as to supply power to the power battery and the PTC electric heater. The two heating modes of liquid heating and power battery self-heating are carried out at the same time, on the basis of ensuring the safety of the power battery, the heating time of the power battery is greatly shortened, the temperature rise speed of the power battery is effectively increased, the heat loss in the preheating process of the power battery is reduced, and the power battery is heated while the temperature rise speed of the power battery is increased. The engine can be heated in advance, and the running efficiency of the vehicle is guaranteed.
本发明公开了一种动力电池加热的控制方法、存储介质和增程系统、重卡,动力电池加热的控制方法,包括:确定车辆满足驻车加热条件;控制车辆进入原地暖机模式,其中,在原地暖机模式下,控制增程器怠速运转以为动力电池和PTC电加热器供电。液热和动力电池自加热两种加热方式同时进行,能够在保证动力电池安全的基础上,大大缩短动力电池的加热时间,有效提高动力电池的温升速度,减少动力电池预热过程中的热量损失,并且在提高动力电池的温升速度的同时,可以让发动机提前热机,保证车辆的运行效率。
