1. A thermal management system for a vehicle having an electric traction motor for moving the vehicle, and a battery pack configured to provide power for driving the electric traction motor, the thermal management system comprising:

  • a battery pack heater configured to transfer heat to the battery pack;

    a second thermal load heater configured to transfer heat to a second thermal load, wherein the second thermal load heater is selectively thermally connectable to the battery pack to transfer heat from the second thermal load heater to the battery pack; and

    a control system, wherein, when the vehicle is connected to an external energy source and the battery pack is at sufficiently low temperature, the control system is configured to control the temperature of the battery pack by activating the second thermal load heater and thermally connecting the second thermal load heater to the battery pack in response to a failure of the battery pack heater.
