Abstract
Abstract A vehicle storage battery system having a storage battery with three integrally manufactured separate storage battery portions, a battery control and a switch for selecting between the operating states for the system. The storage battery has a main battery portion with a capacity sufficient for starting the engine of a vehicle under normal circumstances, a first standby battery portion and a second standby battery portion. The first and second standby battery portions when connected in series have a combined voltage and current output which is greater than the voltage and current output of the main battery portion when in a discharge state. The voltage and current output of the first and second standby battery portions each are less than the main battery portion when the standby battery portions are connected in parallel. The battery control has a first circuit connecting the first and second standby battery portions in series for charging the main battery portion when in a discharged state, and a second circuit connecting the first and second standby battery portions in parallel for recharging the standby battery portions from the main battery portion. The first circuit includes a limiting resistive element connected in series with the first and second standby battery portions for restricting the charging current flow from the standby battery portions to the main battery portion to a predetermined safe level. The second circuit includes a voltage regulator and a limiting resistive element connected to each of the first and second standby battery portions to provide a constant, uniform recharging voltage to each of the standby battery portions and to restrict the recharging current flow to the standby battery portions to a predetermined safe level. The system is provided with a galvanometer for indicating the flow of charging current to the main battery portion. The battery control may be connected to the storage battery by a cable for remote operational control of the system.
