ElvoDrive – optimal for heavy urban traffic

ElvoDrive

The standard hybrid system ElvoDrive transmits the required power as 100% electrical energy. The generator and the drive motor feature extremely high efficiency across a wide operating range. The best conditions for minimal consumption and low emissions. This makes it ideal for heavy urban traffic with many stops and lower average speeds. 100% electrical propulsion over certain distances? No problem for the ElvoDrive.

DIWAhybrid – ideal for higher average speeds

Elvo Drive

The DIWAhybrid parallel system relies on the tried and tested DIWA transmission. A low-loss asynchronous electric motor supports the diesel engine during start-up and acceleration. When the driver applies the brakes, the electric motor functions as a generator. Then, it works as a primary retarder that supplements the DIWA secondary retarder to its full capacity.

You benefit from reduced wear on your brakes, and the environment is burdened with less particulate matter. The energy recovered during the braking process is stored in high-performance capacitors, called "supercaps".

Ensures stable states: The converter

Two hybrid solutions – two objectives:
Saving the environment and economical driving.

Umrichter DIWA

The key component in both solutions is a specially developed converter. Irrespective of the selected storage components, the converter ensures stability of the energy balance up to total energy management.
