<p><P>PROBLEM TO BE SOLVED: To provide a battery pack which can be carried to a location where no commercial power source can be obtained, is inexpensive and easy to handle, and can output an AC voltage equivalent to a commercial power source voltage. <P>SOLUTION: The battery pack 100 includes: (a) a cell group 110 formed by connecting a plurality of cells 111 in series; (b) a discharge control circuit 120 for converting the DC voltage of the cell group into an AC voltage; (c) an AC output terminal 122 for supplying the output of the discharge control circuit to an electric device; (d) a charge control circuit 123 converting the commercial power source voltage into a DC voltage and charging the cell group; and (e) a charge terminal 124 for supplying power from the commercial power source to the cell group, and these components are housed in a case. (f) The AC output terminal 122 can be connected to a plug socket for power input to an electric device driven by the commercial power source, and (g) the charge terminal 124 can be connected to a receptacle of the commercial power source. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
