The invention is suitable for the technical field of automobiles, and provides a battery thermal management method and device, a vehicle-mounted terminal and a vehicle. Determining a driving condition of the vehicle based on the driving information; determining a power consumption range of the battery based on the driving information; based on the driving working condition and the electric quantity consumption range, determining a thermal management threshold value of the battery; and if the current temperature of the battery meets the judgment condition corresponding to the thermal management threshold, performing thermal management control corresponding to the thermal management threshold on the battery. Compared with the prior art, according to the method, the heat management threshold value corresponding to the battery at the moment can be flexibly determined in combination with the driving working condition and the electric quantity consumption range, heat management control over the battery can be flexibly executed in combination with the heat management threshold value, and therefore unnecessary energy consumption is reduced, and the energy utilization efficiency is improved.

    本申请适用于汽车技术领域,提供了一种电池热管理方法、装置、车载终端及车辆,所述方法包括:获取车辆的行驶信息;基于行驶信息,确定车辆的行驶工况;基于行驶信息,确定电池的电量消耗范围;基于行驶工况和电量消耗范围,确定电池的热管理阈值;若电池的当前温度符合与热管理阈值对应的判断条件,则对电池进行与热管理阈值对应的热管理控制。与现有技术相比,本方法可以结合行驶工况和电量消耗范围灵活确定此时电池对应的热管理阈值,可以结合该热管理阈值灵活执行对电池的热管理控制,从而减少了不必要的能耗,提高了能量利用效率。
