Abstract
The present solution preserves an amount of charge sufficient to reach a nearest or most convenient charger in a battery of a vehicle during a prolonged vehicle disuse. The solution can include a data processing system that can identify an inactive state of a battery and determine that the vehicle should enter an energy reservation mode. The data processing system can identify a vehicle charger and determine, based on a location of the vehicle and the charger, an amount of energy needed for the vehicle to reach the charging unit. The data processing system can determine a power reservation threshold for the first battery and modify, based on the power reservation threshold, a level of energy provided by the first battery to the second battery to maintain at least the first amount of amount of energy in the first battery.
