● Powertrain isolation; 6.1 Crash detection Inertia switches are fitted on Riversimple vehicles. If the vehicle is involved in a collision the switch will cut power to the powertrain contactors and hydrogen solenoid, isolating both the high voltage electronics and hydrogen supply. The fuel cell will continue to run until residual hydrogen in the supply lines is depleted. -
Page 19: Powertrain Isolation
Riversimple Operating Manual ● The vehicle should be inspected by trained technicians before being operated or refuelled. An algorithm is also implemented within the HVC that continually monitors the hydrogen mass flow rate to the fuel cell based on tank pressure and temperature readings. Limits to flow are set, which if exceeded also lead to a hydrogen system fault notification and isolation of the tank, as described above.
