ABSTRACT:
A special storage battery has a pair of output terminals and a separate pair of input terminals. Comprised within the special battery is a sealed maintenance-free automotive-type storage battery with a pair of battery electrodes. A compact inverter-type battery charger is connected between the input terminals and the battery electrodes, and a control arrangement is connected between the battery electrodes and the output terminals.
The input terminals are provided in the form of a recessed male receptacle adapted to connect with: i) a 120 Volt/60 Hz power line by way of a power cord having a female plug means at its one end and an ordinary power plug at its other end, or ii) a 12 Volt/DC source by way of a power cord having a female plug means at its one end and exposed conductors at its other end.
The battery charger is operative to provide battery charging in an automatic manner from either 120 Volt/60 Hz or 12 Volt/DC.
The control arrangement comprises: i) electrically actuatable contactor means operable on command to make connection between the battery electrodes and the output terminals, ii) voltage sensing means operative to prevent the contactor means from being or remaining actuated in case the voltage present across the output terminals falls outside a predetermined band of values, and iii) over-current protection means operative to prevent current from/to the output terminals from exceeding a predetermined magnitude for longer than a brief period.
