The present invention relates to a battery thermal management system for an electric vehicle, and to a method and vehicle control system. More specifically, the battery thermal management system comprises a communication unit for transmitting and receiving data packets, a control unit connected to the communication unit. The control unit is configured to retrieve vehicle diagnostic data from a plurality of electric vehicles, the data comprising a battery temperature. Furthermore, the control unit is configured to retrieve a planned route of a first vehicle, and environmental data associated with the planned route, determine a thermal management scheme for the first vehicle based on the vehicle diagnostic data and the environmental data. The thermal management scheme comprising instructionsfor controlling heating and/or cooling of the traction battery pack of the first vehicle. The inventive system allows for precise predictions of the thermal load for traction batteries of electric vehicles, and therefore improved thermal management which reduces maintenance requirements and prolongs the expected lifetime of the electric vehicle.

    本发明涉及一种用于电动车辆的电池热管理系统,并且涉及一种方法和车辆控制系统。更具体地,该电池热管理系统包括用于发送和接收数据包的通信单元、连接到该通信单元的控制单元。该控制单元被配置为从多个电动车辆检索车辆诊断数据,该数据包括电池温度。此外,该控制单元被配置为检索第一车辆的规划路线以及与该规划路线相关联的环境数据、基于该车辆诊断数据和该环境数据来确定用于该第一车辆的热管理方案。该热管理方案包括用于控制对该第一车辆的牵引电池组进行加热和/或冷却的指令。本发明的系统实现对电动车辆的牵引电池的热负载的精确预测,并且因此改善了热管理,这减少了维护要求并延长了电动车辆的预期使用寿命。
