Bosch to Offer Micro-Hybrid System in 2006
28 September 2005
|Bosch micro-hybrid system|
The start-stop system, which shuts off the engine when the vehicle is at rest and restarts it when the driver steps on the pedal, has already been selected for use by an unnamed automaker in Europe for introduction on a new model nest year.
A micro-hybrid system provides no assist for propulsion. The Bosch estimates that its Smart Electronic Start/Stop micro-hybrid System can improve fuel efficiency by as much as 8%.

Bosch is also developing electrical motors for mild and full hybrid drives that can be directly integrated into the powertrain.
The mild drives, with motor output of up to 25 kW, will provide the boost assistance and support regenerative braking for an improvement in fuel consumption of some 15%. The strong or full hybrids will use motors of up to 75 kW (or more) and support all-electric operation for short distances.
Bosch is ramping up its development work for hybrids. The “Project Center Hybrid Systems” had 60 staff at the end of 2004, which will increase to 130 by the end of this year. With support from other Bosch Divisions, that raises the number of employees focused on the hybrids market to some 200.
