Renault Scenic Vision has an all-new platform that is currently in the prototyping phase at Renault Group’s innovation labs. The platform is purpose-designed to fit all the components: the electric motor, hydrogen engine, battery, fuel cell and hydrogen tank. The engine is at the rear, so there is enough space for the 2.5 kg hydrogen tank at the front; the fuel cell is under the floor, at the back of the platform, behind the battery.
Optimal travel times
This propulsion system’s operation is simple and efficient. The car can be driven as a conventional electric vehicle, without using the fuel cell, on daily trips. When there is a requirement to travel longer distances, a route planner calculates the power the fuel cell needs to supply to keep the battery charged for longer, so that there is no need to charge it on the way. The point of using the fuel cell on long journeys is that it’s quicker to top up the hydrogen tank than to charge the battery. This way, there is no need to charge the battery until the car reaches its destination. When the weather is cold, the hydrogen range-extender also keeps the battery at the right temperate for optimal operation and extra range.
Renault Scenic Vision’s hybrid electric and hydrogen powertrain has all the advantages of electric motors: instant acceleration, less noise and no vibration. And no pollution, because the car discharges nothing but water when you use it. There are several advantages to this platform and this new kind of propulsion system: you can drive long distances only stopping briefly to fill the hydrogen tank (roughly every three hours) and they provide an appealing alternative to all-electric motors – even though they are still in the exploratory phase.
