The integrated design of DC/DC+oil pump+air pump+high-voltage power distribution (single/double main drive, large/small bodywork, air conditioner, heater) can meet the needs of heavy trucks with different technical routes such as pure eletric/battery swapping/fuel cell eletrical, and realize the vehicle four-in-one integrated platform product application. The software adopts V/F and open-loop vector control to meet the performance requirements of the vehicle auxiliary drive system.
The multi-axle coordinated linkage control strategy ensures uninterrupted power during gear shifting; Motor control is integrated with the gearbox control software, and the shifting performance is better; Compared with the centralized scheme, the electric drive system of the whole vehicle can achieve a weight reduction of more than 400 kg, which significantly improves the economy of the whole vehicle, and is suitable for 49 t standard-load tractors.
With an integrated software design of high-speed flat wire motor and controller, decelerator and gearbox.The electric powertrain system of the vehicle is more than 100 kg lighter than the centralized solution, which is appliable to 60 t-90 t heavy-duty dump truck.
