The invention provides a vehicle battery heating method and device, a vehicle-mounted terminal and a vehicle, and the method comprises the steps: monitoring the temperature of a battery and the charge quantity of the battery in real time, so as to preheat the vehicle battery through the heat consumed by the vehicle battery in a low-temperature and low-charge state of the battery; whether the battery is heated or not is determined according to the comparison result of the vehicle battery consumed heat and the battery unfreezing energy, and the situation that when the unfreezing energy is smaller than the battery heating consumed energy, a battery heating strategy is still called is avoided; the problem that the driving endurance and even lie down of a user who may deteriorate low-temperature low-charge-quantity driving is avoided, normal starting and running of the vehicle in a low-temperature environment are guaranteed, vehicle faults or performance reduction caused by battery problems are avoided, and therefore the driving experience of the user is improved; through accurate temperature control and heat management, the stability and performance of the vehicle in various environments are improved, and subjective judgment of designers on low charge quantity is avoided.

    本申请提出的一种车辆电池加热方法、装置、车载终端及车辆,该方法包括:通过实时监测电池温度和电池电荷量,从而在电池低温低电荷量的状态下通过车辆电池消耗热量对车辆电池进行预热,并根据车辆电池消耗热量和电池解冻能量的比较结果来决定是否对电池进行加热,避免“解冻”能量小于电池加热消耗能量时仍然调用电池加热策略;避免了可能恶化低温低电荷量行车的用户行车的续航甚至趴窝的问题,保证了车辆在低温环境下的正常启动和运行,避免了因电池问题而导致的车辆故障或性能下降,从而提升了用户的驾驶体验;通过精确的温度控制和热量管理,提高了车辆在各种环境下的稳定性和性能,避免了设计人员对低电荷量的主观判断。
