<p><P>PROBLEM TO BE SOLVED: To suppress an increase of components when power is supplied to a step-up converter CV as an in-car power conversion circuit from each of high-pressure batteries 10a and 10b. <P>SOLUTION: An electric path L1 connecting the positive electrode of a high-pressure battery 10a with the high-potential input terminal of a step-up converter CV is provided with: a high-potential relay 30 that opens or closes the electric path L1. An electric path L2 connecting the positive electrode of a high-pressure battery 10b with the high-potential input terminal of the step-up converter CV is provided with a high-potential relay 34 that opens or closes the electric path L2. The electric path connecting the negative electrode of the high-pressure battery 10a with the low-potential input terminal of the step-up converter CV is mutually used in common with the electric path connecting the negative electrode of the high-pressure battery 10b with the low-potential input terminal of the step-up converter CV and a low-potential relay 32 to open or close this electric path L3 is provided. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
