SAFETY SYSTEM OF FUEL CELL VEHICLE AND CONTROL METHOD FOR THE SAME |
| 摘要 |
Disclosed are a safety system of a fuel cell vehicle and a control method for the safety system. A safety system of a fuel cell vehicle using a fuel cell and a high voltage battery as a power source may include: a power switch disposed on a power wire connecting the power source and a power load to each other; an insulation resistance measuring device measuring an insulation resistance between the power wire and a chassis; and a controller controlling an operation of the power switch based on a measured insulation resistance measured by the insulation resistance measuring device. When the measured insulation resistance is equal to or less than a reference resistance, the controller enters a safe mode and the power switch is turned off to thereby block power supplied to the power load. |

1. A safety system of a fuel cell vehicle using a fuel cell and a high voltage battery as a power source, comprising:
a power switch disposed on a power wire connecting the power source and a power load to each other; an insulation resistance measuring device configured to measure an insulation resistance between the power wire and a chassis; and a controller configured to operate the power switch based on a measured insulation resistance, wherein when the measured insulation resistance is equal to or less than a reference resistance, the controller enters a safe mode and the power switch is turned off to block power supplied to the power load. |
