THE FULL POWER OF HYDROGEN
It is in February 2015 that GreenGT Technologies, a french subsidiary of the Swiss group GreenGT, is starting to integrate a fuel cell that supplies an electric-hydrogen engine to a utility vehicle of the french Post of Dole in the Jura department.
The truck (called Maxity H2) is put into service for one year and serves as a test in France for electric-hydrogen propulsion from GreenGT's knowledge. The vehicle, equipped with a 20 kW fuel cell and a Li-ion battery that power the engine, has a range of about 200 kilometers and its battery can be recharged in 6 hours. The fuel cell installed on the Maxity makes it possible to heat the passenger compartment thanks to the heat released to avoid using the energy of the battery and therefore to preserve the autonomy.
Commissioned in February 2015, the truck had, a year later, traveled 10 000 km in 150 days.
The fuel cell integrated by GreenGT on this utility proves, with this conclusive test, that the electric-hydrogen alternative not only gives a much higher efficiency than the electric and a total cleanliness but is applicable to many spots requiring high-power motors.
- Average autonomy up to 200 km (100 km thanks to the batteries + 100 km thanks to the battery)
- Maximum speed of 90 km / h
- Robotic gearbox - Asynchronous electric motor: 400 V / 47 kW - (270 Nm)
- On-board energy: 42 kWh - Lithium-ion technology / Iron Phosphate (Valence Technology)
- 4 battery packs with a total weight of 400 kg
- Full recharge time including battery equalization phase: 7 hours
- On-board charger, allowing charging on a single 3-phase power supply
- On-board energy: 45 kWh
- Hydrogen cell: 20 kW
- 2 hydrogen tanks, of 75 liters each, allowing to store 4 kg of H2 at 350 bars
- Total weight of the kit: 300 kg - Reminder on the operation of the battery
