Abstract
Systems and methods for controlling a temperature of a plurality of batteries of a vehicle are described. The systems and methods may transfer heat from a fuel cell system to the plurality of batteries of the vehicle. The heat produced by the fuel cell system may be transferred to the plurality of batteries through at least one heat transfer system.
Claims20
A vehicle, comprising:
- a plurality of ground engaging members;
- a frame supported by the plurality of ground engaging members;
- a battery system including a plurality of batteries supported by the frame;
- a fuel cell system supported by the frame;
- a vehicle propulsion system supported by the plurality of ground engaging members, the vehicle propulsion system coupling the battery system to at least one of the plurality of ground engaging members;
- and
- a heat transfer system supported by the frame, the heat transfer system transferring heat produced by the fuel cell system to the battery system to warm the plurality of batteries when a temperature of the plurality of batteries is below a desired temperature.
A method for controlling a temperature of a plurality of batteries, the method comprising the steps of:
- monitoring a temperature associated with the plurality of batteries;
- and
- transferring heat from a fuel cell system to the plurality of batteries when a temperature of the plurality of batteries is below a desired temperature.
A method for controlling a temperature of a plurality of batteries, the method comprising the steps of:
- receiving an indication of a future use;
- monitoring a temperature associated with the plurality of batteries;
- determining a time period in advance of the future use needed to warm the plurality of batteries to a desired temperature;
- and
- during the time period transferring heat to the plurality of batteries to warm the plurality of batteries while the temperature of the plurality of batteries is below the desired temperature.
