POWER SUPPLY SYSTEM FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a power supply system for a vehicle, capable of reducing a risk of leakage from a power cable due to collision and capable of preventing the generation of noise of a car radio due to an external radio wave picked up by the power cable during traveling.SOLUTION: A power supply system for a vehicle comprises: a power supply inverter 26 converting DC supplied from a battery 16 to AC; a control box 28 for controlling the supply of the AC converted by the power supply inverter 26 to the outside of the vehicle; a junction box 10 connected to the battery 16, a motor inverter 8 and the power supply inverter 26 and switching the supply of DC from the battery 16 to the motor inverter 8 and the power supply inverter 26; and a power cable 30 connecting the junction box 10 with the power supply inverter 26. The junction box 10 interrupts the supply of DC to the power cable 30 when the vehicle 1 is in a ready-to-travel state.
