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 instructions for 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.
