Hybrid drive solutions for utility vehicles

Technology and application examples: hybrid

By definition, hybrid drive systems consist of two drive components and two energy stores. However, unlike diesel-electric drive systems, both motors, the internal combustion engine and the electric motor, are mechanically coupled to the drive train. As with a fully electric drive system, an inverter (see VECTOPOWER from ARADEX) is required between the electric motor and the battery.

There are different variants for implementing hybrid drive technology. While parallel hybrids have two drive trains that act simultaneously, serial hybrids use the internal combustion engine to charge the battery (= diesel-electric).

Another, fundamental distinction is between a self-sufficient and a plug-in hybrid. An autonomous hybrid drive charges the accumulators of its electric motor exclusively via the built-in generator. The batteries of a plug-in hybrid, on the other hand, can also be charged at a socket.
