32. What happens if hydrogen in the hydro-
gen tank is completely consumed?
The fuel cell stops working if hydrogen is no longer available.
However, the FCEV can run for an additional distance (About 2
miles (3 km)) in EV mode where the vehicle runs only on battery
power. Mileage in EV mode can vary depending on the "status of
charge" (SOC) of the high voltage battery, so move your vehicle to
the nearest shoulder on the road. Then, we recommend that you
contact an authorized HYUNDAI dealer for service.
33. If the hydrogen gas tank is fully refu-
eled, how much farther can the FCEV
run?
It can travel as far as 300~370 miles (500~600 km) at a constant
vehicle speed of 50 mph(80 kph). Realistically though, this travel
distance is shorter due to normal acceleration and deceleration
when driving.
34. Which mechanism allows for the hydro-
gen gas tank to be refueled, and is it
possible to refuel the tank as much as
you need? Is it possible that the tank
may not be fully refueled?
The tank is refueled by utilizing the difference in hydrogen pressure
between the refueling station and the vehicle. When refueling, the
hydrogen gas pressure of the refueling station is higher than that of
the vehicle. The act of refueling can be stopped as desired.
Normally, the gas tank is not fully refueled with hydrogen if the sta-
tion's hydrogen pressure is not sufficiently high, or if the station sys-
tem cannot communicate with the vehicle.
❈
System and the vehicle communicates the temperature and pres-
sure of hydrogen gas via wireless network.
