Abstract
An interconnectable power supply module includes a battery; a battery charger for charging the battery; a power generator capable of converting an electrical charge stored in the battery to generate output power for an external load; a control unit for controlling operation of the power supply module; a power supply plug for receiving external power from an external power source; a power supply socket capable of coupling the external power received from the external power source to an adjacent power supply module; an external load output socket, selectively coupled to one of the external power source and the power generator, for providing output power to the external load; and a connecting terminal capable of coupling the external load output power to the adjacent power supply module.
Claims34
An interconnectable power supply module comprising:
- a battery;
- a battery charger operating to charge said battery;
- a power generator operating to convert an electrical charge stored in said battery to generate output power for an external load;
- a power supply plug for receiving external power from an external power source;
- a power supply socket configured to couple the external power received from the external power source to an adjacent power supply module;
- an external load output socket on which output power is supplied to the external load from one of the external power source and said power generator;
- and
- a connecting terminal selectively coupling the external load output power to the adjacent power supply module.
An expandable power supply for supplying power to an external load, said expandable power supply comprising a plurality of adjacent power supply modules, each power supply module comprising:
- a battery;
- a battery charger operating to charge said battery;
- a power generator operating to convert an electrical charge stored in said battery to generate output power for the external load;
- a power supply plug for receiving external power from an external power source;
- a power supply socket configured to couple the external power received from the external power source to an adjacent power supply module;
- an external load output socket on which output power is supplied to the external load from one of the external power source and said power generator;
- and
- a connecting terminal selectively coupling the external load output power to the adjacent power supply module.
