Abstract
Aspects of the subject disclosure relate to predictive vehicle battery temperature regulation. A device implementing the subject technology may include a processor configured to obtain different types of data associated with a route projection of a vehicle. The processor can determine a thermal demand projection of the vehicle that maps to the route projection based on the different types of data. The processor also can adjust a temperature of a battery of the vehicle to within a predefined temperature range based on the thermal demand projection for the route projection.
Claims20
A vehicle management system, comprising:
- a controller configured to:
- obtain different types of data associated with a route projection of a vehicle;
- determine a thermal demand projection of the vehicle that maps to at least a portion of the route projection based on the different types of data;
- and
- adjust a temperature of a battery of the vehicle to within a predefined temperature range based on the thermal demand projection for the at least a portion of the route projection, the temperature of the battery being adjusted by a temperature delta that is based on an amount of energy change in the battery associated with the thermal demand projection.
A method of managing a vehicle, the method comprising:
- determining a route projection of a vehicle based at least in part on user input;
- obtaining thermal loading data comprising different types of data associated with the route projection;
- determining a thermal demand projection of the vehicle that maps to at least a portion of the route projection based on the thermal loading data;
- and
- adjusting a temperature of a battery of the vehicle to within a predefined temperature range at least a threshold time prior to the vehicle reaching a type of terrain at a location of a route that corresponds to the at least a portion of the route projection based on the thermal demand projection, the temperature of the battery being adjusted by a temperature delta that is based on an amount of energy change in the battery associated with the thermal demand projection.
A vehicle, comprising:
- a battery;
- a temperature control unit;
- and
- a controller configured to:
- determine a thermal demand projection of a vehicle that maps to at least a portion of a route projection of the vehicle based on different types of data associated with the route projection;
- and
- adjust, using the temperature control unit, a temperature of the battery to within a predefined temperature range by increasing the temperature of the battery based on the thermal demand projection being predicted to cause the temperature of the battery to decrease beyond a first temperature threshold or by reducing the temperature of the battery based on the thermal demand projection being predicted to cause the temperature of the battery to increase beyond a second temperature threshold, the temperature of the battery being adjusted by a temperature delta that is based on an amount of energy change in the battery associated with the thermal demand projection.
