PROBLEM TO BE SOLVED: To reduce a size of a power supply device for a vehicle while sufficiently securing safety of a worker during inspection work, etc. SOLUTION: In a battery pack 21 supplying electric power to a motor generator 10 for traveling, a high-voltage battery 12 comprises a first assembled battery 32 on a side of one end side output terminal 22a and a second assembled battery 33 on a side of the other end output terminal 22b which are formed by a plurality of electric cells in series, respectively. A relay unit 24 for opening/closing electric connection between the first assembled battery 32 and the one end side output terminal 22a is stored in a battery box 20. A plug unit 31 for opening/closing electric connection between the first assembled battery 32 and the second assembled battery 33 is installed between the first assembled battery 32 and the second assembled battery 33 in a position on the other end side relative to a position of an intermediate potential of the high-voltage battery 12. Maximum voltage v2 of the second assembled battery 33 is set to be safety voltage. COPYRIGHT: (C)2013,JPO&INPIT |
