Claas showcased semi-electric and all-electric propulsion systems at Agritechnica this past November. The two systems represent the company’s ongoing testing of alternative drives.
The e-hybrid system mounted on a Lexion concept combine uses battery power to offset surge load power needs. This allows the use of a smaller diesel engine that can operate more smoothly at lower rpm’s and use less fuel. The e-hybrid combine was field-tested in 2023.
The Lexion e-hybrid drive train is equipped with a 536-hp. diesel engine. A drive belt on the drive train connects it to a 40-kW electric motor/alternator, a 3-kWh battery, and a 48-volt inverter. The electrical system is designed to operate in the low-voltage range (<60-volt touch), eliminating the need for special training by servicing personnel.
Under normal load, the system maintains a charge on the battery. When the load increases, the electric motor, with its instant torque, provides an immediate, temporary assist. This reduces the need for the diesel engine to speed up and reduces fuel use by 8 to 10 percent, as well as CO2 emissions.
If the concept proves itself, it’ll reduce the size of a diesel engine needed on any self-propelled machine. The concept combine would normally be equipped with a 626-hp. diesel. With the battery-powered electric motor assisting, the smaller 90-hp. engine would operate at 1,600 rpm’s versus the larger engine’s normal 1,800 rpm’s.
Also on display was an all-electric Scorpion 732e Telehandler. Unlike the e-hybrid Lexion, the telehandler is reportedly closer to a market launch.
The 732e is a joint development with Liebherr, the maker of Claas’ Scorpion line of telehandlers. In 2022, Liebherr shared an emission-free, battery-powered telehandler concept.
The 732e is equipped with two independent 90-kW electric motors approximately equal to 121 hp. The 64-kWh modular battery offers up to 4 hrs. of use and is recharged with the onboard, 22-kW battery charger.
The electric telehandler has a lift capacity of 3.2 tons and can reach nearly 23 ft. The top speed is 18 1/2 mph.
