Abstract: Disclosed embodiments include systems, vehicles, and computer-implemented methods for maintaining the operational condition of a battery system incorporated in a vehicle or otherwise stored and, based on weather information, to adjust reserve capacity in the battery system prevent damage as a result of weather conditions. In an illustrative embodiment, a system includes a communications interface configured to communicate with a weather information source over a network to receive data on anticipated weather conditions; and a battery controller configured to interoperate with the communications interface and to control a reserve capacity level for a battery system, wherein the battery controller is configured to: determine whether the reserve capacity level is sufficient to maintain operational condition of the battery system under the anticipated weather conditions; and modify the reserve capacity level responsive to a determination that the reserve capacity level is sufficient to maintain the operational condition of the battery system.

Abstract: Various disclosed embodiments include illustrative control units, systems, and methods. In an illustrative embodiment, a control unit includes a processor and non-transitory computer-readable media that stores computer-executable instructions configured to cause the processor to determine a start charging time, receive a battery temperature value, and instruct the thermal control system to start heating the battery responsive to the start charging time and the battery temperature value in an energy saving way.

Abstract: Systems, methods, and devices for a multi-purpose thermal component are provided. The system can include a thermal component to interface with a battery and an electrical component, and a controller in electrical communication with the thermal component. The controller can cause the thermal component to charge the electrical component. The controller can cause the thermal component to transfer thermal energy with the battery.
