Abstract
A battery management system thermally conditions a battery assembly prior to a determined upcoming time or the battery assembly's arrival at an upcoming location, and selects a source of the power used for the thermal conditioning.
Claims20
A method comprising:
- determining a conditioning time or a conditioning location to thermally condition a battery assembly prior to (a) a determined upcoming time in which the battery assembly will discharge energy to power one or more loads or (b) arrival of the battery assembly at an upcoming location at which the battery assembly will discharge energy to power the one or more loads;
- selecting a first source of power to be used for thermal conditioning the battery assembly at the conditioning time or the conditioning location, the first source of power selected from among multiple different sources of power based at least in part on respective availabilities of the different sources of power for changing a temperature of the battery assembly at the conditioning time or the conditioning location;
- and
- thermally conditioning the battery assembly at the conditioning time or the conditioning location using power from the first source of power.
1 more element
A system comprising:
- a controller configured to control a heating and/or cooling assembly onboard a vehicle to thermally condition a battery assembly onboard the vehicle, the controller configured to determine a conditioning time at which the heating and/or cooling assembly thermally conditions the battery assembly prior to the vehicle reaching an upcoming location that the vehicle is to travel to or through, the controller configured to determine the conditioning time based at least in part on both 1) a predicted or measured ambient temperature at the upcoming location and 2) an actual or expected duty cycle of the battery assembly while the vehicle is at the upcoming location, and,
- the controller is configured to determine respective availabilities over time of multiple different sources of power to power the heating and/or cooling assembly, the controller configured to select a first source of power from the multiple different sources of power to power the heating and/or cooling assembly to thermally condition the battery assembly at the conditioning time based at least in part on the availability of the first source of power indicating that the first source of power is available to change the temperature of the battery assembly at the conditioning time.
A method comprising:
- determining predicted ambient temperatures at one or more of (a) upcoming times or (b) upcoming locations that a vehicle is to travel to or through, the vehicle having one or more loads that are at least partially powered by a battery assembly onboard the vehicle;
- determining a duty cycle of the battery assembly for the vehicle at each of the one or more of the upcoming times or the upcoming locations;
- determining respective availabilities over time of multiple different sources of power to power a heating and/or cooling assembly onboard the vehicle to thermally condition the battery assembly;
- and
- determining a temperature pre-conditioning plan for the battery assembly based on the predicted ambient temperature, the duty cycle of the battery assembly, and the respective availabilities of the different sources of power, the temperature pre-conditioning plan including one or more of:
- first and second conditioning times during which the battery assembly is heated or cooled ahead of the one or more of the upcoming times or the upcoming locations, or
- first and second conditioning locations where the battery assembly is heated or cooled ahead of the one or more upcoming times or the upcoming locations, and
- wherein the temperature pre-conditioning plan dictates, based on the respective availabilities of the multiple different sources of power to change the temperature of the battery assembly, that an off-board charging source of the multiple different sources of power is selected to power the heating and/or cooling assembly to change the temperature of the battery assembly at one or more of the first conditioning time or the first conditioning location, and an onboard source of the multiple different sources of power is selected to power the heating and/or cooling assembly to change the temperature of the battery assembly at one or more of the second conditioning time or the second conditioning location.
