Vehicle conversion procedure

1. Packaging Design

 
  1. FC/PE system
  2. FC/PE Cooling system
  3. H2 supply system
  4. Wire harness
  5. HVCU
  6. Energy flow display
Packing design validates layout feasibility of vehicle components.

2. System Evaluation

 
  1. FC system
    - Performance
    - Efficiency
  2. HVCU control unit inspection test
  3. Battery/PE system
System level evaluation is executed to verify that each system satisfies the design specification.

3. Proto vehicle development

 
  1. Repainting
  2. Disassembly
  3. Components
    installation
  4. Filling hydrogen
After confirmation of systems, proto vehicle is built.

4. Proto vehicle test

 
  1. Calibration
    - Driving control
    - Power control
  2. Test
    - Fuel economy test
    - Drivability test
Vehicle level calibration is done and field test ensures the overall fulfillment of the vehicle development.
