A vehicular power system includes: a secondary battery (B); an up-converter (12) receiving a voltage of the secondary battery at a first connection node thereof, and up-converting a voltage between terminals of the secondary battery (B) and outputting the up-converted voltage at a second connection node thereof; system main relays (SMRP, SMRG) switching between connection and disconnection of the voltage up-converted by the up-converter (12) to and from a load of a vehicle; and a case (140) housing the secondary battery (B), the up-converter (12) and the system main relays (SMRP, SMRG). Preferably the vehicular power supply system further includes a capacitor (23) having one end connected to the second connection node of the up-converter (12) and the case (140) further houses the capacitor (23). Preferably the capacitor (23) includes a plurality of series connected, electric dual layer capacitors. A vehicular power supply system suitable for being mounted in a vehicle and miniaturized, and a vehicle having the system mounted therein, can thus be provided. |
