| What is a hybrid? |
|
“Hybrid” comes from the Latin and means: “mixed, having two origins”. Hybrid vehicles use two types of energy to achieve optimal propulsion. The combusion engine is assisted by the respective hybrid technology. This results in a dual benefit for the user: A hybrid not only reduces fuel consumption, it also provides significant emissions reduction. The most common hybrid technologies are the electric and the hydraulic hybrid.

Characteristics of the electric hybrid
Excess engine power is continually stored over a longer period of time in a battery (blue) and accessed only as needed (light blue).
- Storage medium: Battery
- High energy density, lower power density
- The battery can accept a large amount of energy
- The charging process however is relatively long
- Familiar from passenger cars

Characteristics of the hydraulic hybrid
During braking the kinetic energy is transferred to a hydraulic accumulator (blue) and immediately used when accelerating again (light blue).
- Storage medium: Hydraulic bladder accumulator
- High power density, lower energy density
- A large amount of energy can be stored in a very short time and immediately accessed
- Virtually all of the braking energy can be stored
- Especially suitable when there is already a hydrostatic transmission in the vehicle
- Can be retrofitted
- Ideal for vehicles with short successive start-stop cycles, such as city buses, refuse trucks, fork lifts, pneumatic rollers, telehandlers, shipyard cranes, …
