Cummins has announced it has developed its first electrified power system for off-highway applications. The powertrain concept will be revealed at Intermat 2018 in Paris, France, on April 23-28.
The range extended electric vehicle (REEV) driveline combines battery power with a compact engine-generator, using a four-cylinder Stage V F3.8 engine. It is designed to replace a standard driveline using larger Cummins or competitive diesel engines of up to a 9-liter capacity for applications from wheeled loaders to mobile cranes, and terminal tractors to excavators.
The system uses a high-efficiency traction motor providing continuous torque of 1,850Nm, eliminating the need for gear shifting and dramatically reducing powertrain noise. An instant peak torque boost up to 3,400Nm is available when the machine hits difficult working conditions.
“We are expanding Cummins’ portfolio of products to reflect the alternative power needs of the future. We’re developing a range of options such as alternative fuels, range extenders and full-electric power to complement our Stage V clean diesels and provide customers with the best solution for their machines,” said Hugh Foden, executive director off-highway business, Cummins.
“The variation in off-highway applications means that it is not one-size fits all. Our concept is modular so that it could be applied to a variety of equipment and offer the same range and operation as today, yet deliver significant improvements in efficiency and emissions,” Foden added.
