It’s called the Tatra Force e-Drive and it’s a prototype FCEV hydrogen car that uses fuel cell technology. Time moves forward, and in addition to purely battery-powered vehicles, the alternative vehicles also include those that use hydrogen for power generation.
However, Tatrovka was not alone in this pioneering car, as the entities ÚJV Řež, Devinn, VŠCHT Prague and the Řež Research Center from the ÚJV Group were also involved in the development. It is ÚJV Řež that has rich experience with hydrogen, as this company is behind the experimental hydrogen bus TriHyBus (Škoda 24FC) and behind the hydrogen filling station in Neratovice.
The basis of the utility prototype intended for the mining industry is the third generation of the Tatra Force model series, which debuted this May. The hydrogen e-Drive then stands on an eight-wheeled Tatra chassis with a central support tube and independently suspended semi-axles. Three out of four axles are driven, the total weight is 45 tons.
The drive of the car itself is electric, so it has a traction electric motor with a maximum output of 580 kW (788.5 hp) and a torque of 2,300 Nm. The traction battery Li NMC (lithium-nickel-manganese-cobalt oxide) will then offer a total capacity of 171 kWh, i.e. more than twice the capacity of, for example, the Škoda Enyaq.
The first advantage of the concept is that the traction battery can be charged externally, for example from a charging station. The second source of energy that the vehicle carries with it are two fuel cells (100 kW each) connected to hydrogen tanks. The cells can then, based on the reaction, produce the necessary electricity and send it to the accumulator.
This is followed by another benefit, namely quick refueling of hydrogen in minutes, thus quick and flexible deployment of the truck into operation. The car is also equipped with a Tatra five-speed main gearbox with an electronic shifting system.
The prototype will be used by the factory for various tests and experiments, however, it is assumed that the finished small-series Tatra Force e-Drive FCEV cargo special will see the light of day in the near future. While car manufacturers are not so fond of hydrogen in passenger cars, the opposite is true in the case of trucks. There, the manufacturers wind the future, and so does Tatra.
