METHOD AND APPARATUS FOR DETECTING OPENING AND CLOSING OF PILOT OPERATED SOLENOID VALVE FOR HYDROGEN TANK |
摘要 |
A method and an apparatus for detecting an opening and closing of a pilot operated solenoid valve provided in a hydrogen tank can open or cut off a channel of hydrogen gas supplied to a stack. The method includes receiving a valve opening command; determining whether valve driving input/output signals responding to the valve opening command are abnormal; checking a pressure inside a high pressure hydrogen pipe when it is determined that the valve driving input/output signals are normal; and outputting a valve opening signal when the checked pressure satisfies a valve opening condition. |
