The control apparatus calculates remaining time to complete charge of the battery bank unit based on a temperature of the battery bank unit at a start of the charge of the battery bank unit and a state of charge (SOC) of at least one of the first battery bank and/or the second battery bank at the start of the charge of the battery bank unit.
