The invention belongs to the technical field of new energy automobiles, and particularly relates to a battery temperature control method, device and equipment and a computer storage medium. According to the method, target charging pile information of a vehicle and operation parameters of a power battery of the vehicle are obtained, and according to the target charging pile information and the operation parameters of the power battery, a temperature estimated value and a charging temperature threshold value of the power battery when the vehicle arrives at the target charging pile are determined; and according to the temperature estimated value and the charging temperature threshold value, a target heating mode of the vehicle is determined, and the vehicle is controlled to heat the power battery according to the target heating mode. According to the method, whether the power battery is heated or not in the low-temperature environment can be more accurately determined, the danger of high-power charging of the power battery at the low temperature is reduced, the heat management function of the vehicle in the low-temperature environment is optimized, the working efficiency of charging and discharging of the power battery is improved, and the service life of the vehicle is prolonged. And the vehicle using experience of the user in winter is improved.
本申请属于新能源汽车技术领域,尤其涉及一种电池温度控制方法、装置、设备和计算机存储介质。该方法通过获取车辆的目标充电桩信息以及车辆的动力电池的运行参数,并根据目标充电桩信息和动力电池的运行参数,确定车辆到达目标充电桩时动力电池的温度预估值和充电温度阈值;根据温度预估值和充电温度阈值,确定车辆的目标加热模式,并控制车辆按照目标加热模式对动力电池进行加热处理。该方法可以更加准确的确定出在低温环境下动力电池是否进行加热处理,降低了动力电池在低温下进行大功率充电时的危险性,优化了车辆在低温环境下的热管理功能,不仅提高了动力电池充放电时的工作效率,还提高了用户冬季的用车体验。
