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 for the first time at Intermat Paris.
A range extended electric vehicle driveline (REEV) will be displayed at the Cummins stand during the intermat show on April 23-28.
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 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 1,850Nm, 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 porfolio 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-Highways 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," said 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 location," added Foden.
