First off-highway electrified power system to be revealed by Cummins at Intermat
Cummins announced that the company will show an electrified powertrain concept suitable for off-highway applications at Intermat Paris, April 23-28. A range extended electric vehicle driveline (REEV) will be displayed on Cummins stand F021 in hall 5A for the first time.
Cummins REEV combines battery power with a compact engine-generator, using a 4-cylinder Stage V F3.8 engine. It is designed to replace a standard driveline using larger Cummins or competitive diesel engines up to 9 litres capacity for applications from wheeled loaders to mobile cranes, terminal tractors to excavators. The system uses a high-efficiency traction motor providing continuous torque of 1,850 Nm, eliminating the need for gear shifting and dramatically reducing powertrain noise. An instant peak torque boost up to 3400 Nm 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.
The REEV system's electronic control logic blends the energy use between the engine-generator and battery to best suit the operational needs. The engine-generator will automatically recharge the battery pack as needed. Operators will also have the option for overnight charging with plug-in capability.
"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," added Foden.
The modular design allows the system to be aligned with the capability and duty cycle of the machinery. The high-density battery enclosure and engine can be sized to deliver the best balance between ultra-low emission and zero emission operation.
“Our REEV concept will be viable for emerging opportunities where even lower emissions are required to improve air quality, particularly in urban and port side locations,” concluded Foden.
