METHOD AND DEVICE FOR DETECTING AN OPENING AND CLOSURE OF A FOREIGN-CONTROLLED SOLENOID VALVE FOR A WATER TANK

摘要

A method and apparatus for detecting opening and closing of an externally controlled solenoid valve for a hydrogen tank may open or interrupt a passage of a hydrogen gas supplied to a stack. The method includes receiving a valve opening command; Determining whether valve control input / output signals are abnormal in response to the valve opening command; Checking a pressure within a high pressure hydrogen tube when it is determined that the valve control input / output signals are normal; and outputting a valve opening signal when the checked pressure satisfies a valve opening condition.
