US Patent 7301249 Battery connect/disconnect for an uninterruptible power supply

An uninterruptible power supply (UPS) is provided that can alleviate difficulties in shipping electronic devices containing batteries, such as UPS devices by providing a battery connect/disconnect assembly that can connect and disconnect an internal battery from outside the chassis of the UPS. The UPS comprises an input, output, DC voltage source, electrical circuit, chassis, and connect/disconnect assembly. The input receives input power from an input power source, and the output provides output power to a load. The DC voltage source provides DC power and has first and second terminals. The electrical circuit is operably coupled to the DC voltage source and is capable of receiving the input power and providing the output power. The chassis houses at least the DC voltage source and the electrical circuit. The connect/disconnect assembly is operably coupled to the DC voltage source and is constructed and arranged to be operable from outside the chassis. The connect/disconnect assembly has a first state wherein the DC voltage source is operably coupled to the electrical circuit and a second state wherein the DC voltage source is operably disconnected from the electrical circuit.
