The embodiment of the invention provides a vehicle power supply method and device, a vehicle control unit and a readable storage medium, and relates to the technical field of vehicle power supply, and the method comprises the steps that the first electric quantity value of a first power battery is monitored in real time; under the condition that the first electric quantity value meets the first electric quantity condition, a second power battery is switched on; acquiring a voltage value of a second power battery; and under the condition that the voltage value meets the preset voltage condition, the first power battery is disconnected. In the embodiment of the invention, the electric quantity of the first power battery can be monitored in real time in the running process of the vehicle, and the second power battery is seamlessly switched when the electric quantity of the first power battery is monitored to be insufficient, so that the second power battery supplies power to the vehicle, the influence on normal running of the vehicle due to battery exhaustion is avoided, and the service life of the vehicle is prolonged. Under the condition that normal running of the vehicle is not affected, the battery replacement operation of the vehicle can be completed in a non-inductive mode, and the flexibility of electric energy supplementation of the vehicle is improved.

    本发明实施例提供了一种车辆供电方法、装置、整车控制器及可读存储介质,涉及车辆供电技术领域,包括:实时监测第一动力电池的第一电量值;在第一电量值满足第一电量条件的情况下,接通第二动力电池;获取第二动力电池的电压值;在电压值满足预设电压条件的情况下,断开第一动力电池。在本发明实施例中,可以在车辆运行过程中实时监测第一动力电池的电量,并在监测到第一动力电池的电量不足时,无缝切换至第二动力电池,从而通过第二动力电池为车辆提供电力,避免电池耗尽对车辆的正常行驶造成影响,可在不影响车辆正常行驶的情况下,无感完成车辆的换电操作,提高了车辆补充电能的灵活性。
