Apparatus for supplying power to transmitter of fuel cell vehicle

摘要

A power supply apparatus for a fuel cell vehicle, and provides a power supply apparatus of a fuel cell vehicle. More specifically, an InfraRed (IR) data transmitter transmits and receives data to/from a hydrogen charger and a power supply apparatus, that is connected to the IR data transmitter, selectively supplies power thereto according to the opening/closing of a fuel door. In particular, a sensing apparatus is connected to the power supply apparatus and senses opening/closing of the fuel door and a normal power source that is connected to the sensing apparatus for opening/closing the fuel door selectively supplies power to the sensing apparatus when the normal power source is off.

1. A power supply apparatus for a fuel cell vehicle, comprising:
an InfraRed (IR) data transmitter transmitting/receiving data to/from a hydrogen charger; a power supply apparatus that is connected to the IR data transmitter and selectively supplies power thereto according to the opening/closing of a fuel door; a sensing apparatus that is connected to the power supply apparatus and senses opening/closing the fuel door; and a normal power source that is connected to the sensing apparatus and that selectively supplies power to the sensing apparatus, wherein the normal power source supplies power to the IR data transmitter only in response to the sensing apparatus sensing that the fuel door is opened, and wherein the normal power source stops supplying power to the IR data transmitter when hydrogen charging of the fuel cell vehicle is finished and the fuel door is closed.
