Abstract
A method includes pre-conditioning a battery for charging to support higher rates of charging the battery.
Claims20
A method, comprising:
- identifying a battery charging location;
- setting a target temperature for thermal regulation of a battery pack based on the battery charging location;
- and
- regulating a temperature of the battery pack according to the target temperature.
1 more element
An apparatus, comprising:
- a battery pack;
- a navigation system configured to identify a battery charging location;
- and
- a thermal regulation system configured to regulate an actual temperature of the battery pack based on a target temperature, wherein the thermal regulation system modifies the target temperature based on the battery charging location.
1 more element
A method, comprising:
- identifying a planned route;
- identifying a battery charging location based on the planned route;
- determining a travel energy requirement based on estimated use of a battery pack en route to the battery charging location using the planned route;
- determining an excess energy amount based on the travel energy requirement and a state of charge of the battery pack;
- and
- reducing a temperature of the battery pack using a thermal regulation system upon determining that the excess energy amount exceeds a cooling energy requirement for reducing the temperature of the battery pack.
3 more elements
A method, comprising:
- determining that a battery pack is able to provide excess energy in addition to an anticipated energy usage during travel to a battery charging location;
- decreasing a target temperature for the battery pack in response to determining that the battery pack is able to provide the excess energy;
- and
- cooling the battery pack toward the target temperature prior to arriving at the battery charging location using at least part of the excess energy.
