BATTERY SYSTEM TEMPERATURE AND CHARGE ADJUSTMENT SYSTEM AND METHOD
First Claim
1. A battery system, comprising:
- a battery module;
a thermal management system; and
a battery system controller configured to;
receive data indicative of first operational conditions of the battery module and of second operational conditions of the thermal management system;
determine a desired change to the first operational conditions of the battery module by determining an amount of power available to the thermal management system and to the battery module from one or more power sources; and
enable, to effect the desired change to the first operational conditions, the one or more power sources to provide a first quantity of power to the thermal management system and a second quantity of power to the battery module, and the thermal management system to heat or to cool the battery module to a calculated extent.

Abstract
A battery system includes a battery module, a thermal management system, and a battery system controller. The controller is configured to receive data indicative of first operational conditions of the battery module and of second operational conditions of the thermal management system, determine a desired change to the first operational conditions of the battery module by determining an amount of power available to the thermal management system and to the battery module from one or more power sources, and to enable, to effect the desired change to the first operational conditions, the one or more power sources to provide a first quantity of power to the thermal management system and a second quantity of power to the battery module, and the thermal management system to heat or to cool the battery module to a calculated extent.

15. A battery system controller comprising a processor and a memory, wherein the memory comprises instructions stored thereon that, when executed by the processor, cause the processor to:
-
determine a temperature of a battery module and a state of charge of the battery module; determine a heating or cooling capability of a thermal management system; determine an amount of power available, from one or more power sources, to the battery module and to the thermal management system; determine a desired condition of the battery module based at least in part on the temperature of the battery module, the state of charge of the battery module, the amount of power available to the battery module or to the thermal management system, or a combination thereof; and cause, based at least in part on the desired first condition, the one or more power sources to provide to the thermal management system and to the battery module a desired split of the amount of power available to the thermal management system and to the battery module, and the thermal management system to heat or cool the battery module to a calculated extent. - View Dependent Claims (16, 17, 18, 19)

20. A method of charging a battery module, comprising:
-
determining a temperature of the battery module; determining a state of charge of the battery module; determining a heating or cooling capability of a thermal management system utilized to heat or cool the battery module; determining an amount of power available to the thermal management system and to the battery module from one or more power sources, wherein the one or more power sources comprise at least a regenerative braking system; determining a desired temperature and a desired charge rate or charge capacity of the battery module based on the temperature of the battery module, the state of charge of the battery module, the heating or cooling capability of the thermal management system, the amount of power available to the thermal management system and to the battery module from the one or more power sources, or based on a combination thereof; utilizing the thermal management system to heat or cool the battery module to the desired temperature; and utilizing the one or more power sources to charge the battery module at the desired charge rate or capacity, and to charge to the thermal management system. - View Dependent Claims (21, 22)
