<p><P>PROBLEM TO BE SOLVED: To provide a power supply device for vehicles, which suppresses additional components and reduces the noise of a power circuit at low costs, and to provide a vehicle provided with the device. <P>SOLUTION: The power supply device for vehicles includes: a high-tension battery; an auxiliary battery 16, whose voltage is lower than that of the high-tension battery; a battery fuse 21, one end of which is connected to the auxiliary battery 16 and the other end of which is connected to a first node N1; a power supply line 58 connected to the node N1; a DC/DC converter 14, which is provided between the high-tension battery 12 and the node N1 to perform voltage conversion between the high-tension battery 12 and the auxiliary battery 16; and a fuse box 20 for distributing the power source current for vehicle loads to be operated by receiving the power source current supplied from the power supply line 58. The length of a route from the DC/DC converter 14 to the auxiliary battery 16 via the node N1 is shorter than that of a route from the DC/DC converter 14 to the fuse box 20 via the node N1 and the power supply line 58. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
