  Hydrogen Detection Sensor

  Hydrogen detection sensor is applied near the hydrogen storage container of the fuel cell car (FCEV), near the joints of the hydrogen transfer piping, and around the stack to detect hydrogen leakage.
  Hydrogen detection sensor that is excellent for silicon immunity and mechanical impact is under development applying with thermal conduction technology.

• 

  Hydrogen Pressure Sensor

  Hydrogen pressure sensor is applied to Fuel Cell Stack Inlet and Hydrogen Supply in Fuel Cell Vehicle (FCEV) to monitor the pressure in the Hydrogen Supply Line.
  Development of hydrogen pressure (low pressure) sensor with sensor Die-ASIC circuit and element deterioration diagnostic function is in progress.

  PRA(Power Relay Ass’y)

  Parts that connect/disconnect the drive force between the motor/inverter of the EV, HEV, PHEV and FCEV car battery systems. Developing a 400/800V specification PRA with a high voltage relay and an electronic precharge relay.

• 

  Electronic Precharge Relay

  As a PRA SUB part, it operates before the main relay operates and reduces the voltage difference within the circuit to prevent main relay overload. Developing 400V/800V electronic specifications using semiconductor devices.

• 

  High Voltage Relay

  As a PRA SUB part, it connects and blocks battery electrical energy by physically contacting and separating electrical contact points. Developing a high-voltage relay with increased durability of 400V/800V specifications.
