Lynx dump truck: E-vehicle generates more electricity than it consumes

The Lynx dump truck is not only the largest e-vehicle in the world, but also a veritable power source: the surplus is 200 kilowatt hours per day under optimal conditions.

58 tons empty weight

The dump truck is a vehicle of superlatives. It tips the scales at 58 tons empty and contains a 4.5-ton battery pack. The battery alone is thus far heavier than an average electric car. The vehicle is correspondingly powerful: The battery holds 700 kilowatt hours and the power of 634 kilowatts is converted into a torque of 12,500 newton meters. The top speed of the gigantic vehicle, on the other hand, is rather unimpressive: it travels at a maximum of 40 km/h. Meanwhile, two motors are found inside: a synchronous motor provides the drive described above, while an asynchronous motor operates the hydraulic pumps for the tilt drive, servo assistance and braking systems.

Power generation in the Bernese Jura

The unit will be used in the Bernese Jura, where it will transport up to 65 tons of material across a quarry. The location of the operation is crucial for the basic concept of the vehicle: only under the specific conditions of the hilly landscape can it have a positive energy balance via recuperation. With an unladen weight of 58 metric tons, the Lynx drives onto the slag heap, where it picks up the material to be transported. It then rolls back down with a total weight of 123 tons. As soon as it begins to brake on the downhill stretch, energy is generated via recuperation – and under optimum conditions this exceeds that required for the ascent, so that the vehicle can serve as an electricity producer.

However, the optimal conditions required for this are not always present. The Bernese Jura, for example, is an area where it snows frequently. In order to be able to continue to operate safely, the Lynx then has to be covered with snow chains, which increases energy consumption.
