The invention provides a battery temperature control method and device, a vehicle and a storage medium, and relates to the technical field of vehicles, according to the method, a range extender heat transfer water path is opened by responding to a battery temperature control request, and the range extender heat transfer water path is connected with a range extender and a battery. And the real-time inlet water temperature of the battery is obtained, and the real-time inlet water temperature of the battery is compared with the preset target inlet water temperature. If the real-time inlet water temperature of the battery is smaller than the first inlet water temperature threshold value, the range extender is controlled to be in an on state, and the battery is preheated through a range extender heat transfer water path by means of heat of the range extender; if the real-time inlet water temperature of the battery is larger than or equal to the second inlet water temperature threshold value, the range extender is controlled to be in a closed state. Therefore, the heat of the range extender can be utilized to transmit the water path, the range extender is started to preheat the battery, for a range-extended electric vehicle, the range extender of the vehicle can be used to preheat the battery, additional heating equipment does not need to be added, and the cost can be reduced.
本申请提供一种电池温度控制方法、装置、车辆以及存储介质,涉及车辆技术领域,该方法通过响应于电池温控请求,开启增程器热量传递水路,该增程器热量传递水路连接增程器和电池。获取电池实时进口水温,并比较电池实时进口水温和预设目标进口水温。若电池实时进口水温小于第一进口水温阈值,则控制增程器处于开启状态,利用增程器热量通过增程器热量传递水路对电池预热;若电池实时进口水温大于或等于第二进口水温阈值,则控制增程器处于关闭状态。如此便可以利用增程器热量传递水路,通过开启增程器对电池进行预热,对增程型电动车而言,使用车辆自带的增程器即可对电池进行预热,无需增加额外的加热设备,可以降低成本。
