The invention relates to a battery thermal management method and device, a server, a vehicle, a storage medium and a chip. The method is applied to the server, and the server determines a vehicle sample set based on the accumulated driving mileage and the accumulated use day number of a plurality of vehicles; and adjusting the cooling strategy of the power battery of the vehicle in the vehicle sample set according to the operation data of the power battery of the vehicle in the vehicle sample set to obtain an adjusted cooling strategy of the power battery, and carrying out battery thermal management on the power battery of the vehicle. Historical operation data of a vehicle and a power battery are obtained through a cloud server, targeted battery heat management strategy optimization is carried out on vehicles with different battery health states on the basis of an original vehicle end cooling strategy, and the optimized targeted battery heat management strategy is issued to a corresponding vehicle end for updating. And the health state of the power battery of the vehicle is optimized and controlled in the whole life cycle, so that the service life of the power battery of the vehicle is prolonged to a certain extent.

    本公开涉及一种电池热管理方法、装置、服务器、车辆、存储介质及芯片,所述方法应用于服务器,服务器基于多个车辆的累计行驶里程和累计使用天数确定车辆样本集合后,根据车辆样本集合中的车辆的动力电池运行数据对车辆样本集合中的车辆的动力电池冷却策略调整后得到调整后的动力电池冷却策略对车辆的动力电池进行电池热管理。通过云端服务器获取车辆和动力电池的历史运行数据,在原有车辆端冷却策略的基础上,对具有不同的电池健康状态的车辆进行针对性的电池热管理策略优化,并将优化后的具有针对性的电池热管理策略下发到相应的车辆端进行更新,在全生命周期内对车辆的动力电池健康状态进行优化管控,从而在一定程度上延长车辆动力电池的寿命。
