Power-supply unit

摘要

A power-supply unit has an electric connection box disposed in a vehicle compartment and operable to supply an electric power of a battery to a plurality of loads and a power supply disposed in the vehicle compartment and operable to control first voltage that is supplied from the battery and outputted through the electric connection box and supply second voltage into which the first voltage is controlled in the power supply to the plurality of loads through the electric connection box. The electric connection box includes an electric connection box side input terminal electrically connectable to the battery and an electric connection box side output terminal electrically connectable to the plurality of loads. The power supply includes a power supply side input terminal that is directly connected to the electric connection box side input terminal and a power supply side output terminal that is directly connected to the electric connection box side output terminal. The first voltage is inputted to the power supply side input terminal through the electric connection box and the second voltage is supplied to the plurality of loads through the electric connection box. The power supply is directly supported by and fixed to the electric connection box.
