SYSTEM AND METHOD TO PRESERVE OPERATIONAL CONDITION OF BATTERY SYSTEM DURING COLD WEATHER AND POWER OUTAGES

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.
