Harvesting and tractor specialist Claas has developed and area examined a mix harvester fitted with a component electrical drive system.
As well as, working with fellow German firm Liebherr, it has additionally developed a 100% electrical telehandler.
The semi-electric mix, idea permits self-propelled machines that might usually be powered by a 626hp (460kw) powerplant to run on a much less highly effective 536hp (400kW) engine. An additional profit is that the smaller engine can function at 1600rpm, as a substitute of the conventional 1800rpm.
This smaller engine and diminished velocity is compensated for by a 40kW electrical motor, that in additional power-hungry conditions, resembling in high-yielding areas, travelling uphill or emptying the grain tank, offers the mechanical driveline with a brief time period electrical energy increase.
Changing the standard most output offered by the diesel block, {the electrical} help allows peak masses to be bridged, permitting the mix to persistently function within the optimum efficiency vary.
Flattening peak masses, the hybrid idea is claimed to cut back gasoline consumption by as much as 10%. In simpler situations the place the total energy of the diesel engine will not be wanted, a generator offers a regenerative operate, changing extra energy into electrical energy to be saved within the 3kWh battery.
The semi-electric system operates within the low, sub 60v vary, so doesn’t require the advanced security precautions related to higher-voltage drives.
Claas says that this implies upkeep might be carried out with none particular coaching.
At this stage, the challenge continues to be on the early idea and testing levels, and it isn’t but identified if the system will make it to the manufacturing stage.
In different Claas information, the corporate is the newest to approve hydrogenated vegetable oil (HVO) for its merchandise, though it’s already extensively marketed as a direct drop-in substitute for diesel gasoline.
Nevertheless, the corporate notes in its newest bulletin that whereas battery energy could also be appropriate for lighter functions, an electrically powered Jaguar forage harvester would must be twice the scale and weight to offer the identical energy and vary as the present diesel fashions, so for the foreseeable future, “conventional” fuels will proceed to be essential.
Preserving the diesel engine as the first energy supply is seen as important by the corporate. Dr Martin von Hoyningen-Huene, who heads the tractor division, notes that “there are not any actual options to the combustion engine for high-performance agricultural machines within the foreseeable future”.
The corporate additionally states that gaseous fuels resembling methane or hydrogen even have vital disadvantages by way of their vitality density and thus their vitality storage necessities, whereas the infrastructure for provide and storage of those supplies continues to be a great distance away.
