Italian motorsport electronic specialists shows off
its regenerative braking system
Regenerative braking systems for 2009 are rapidly appearing, Magneti Marelli has revealed it is to join Flybrid, Williams, Zytek and Bosch in offering an off the shelf solution for Formula 1. Its KERS is capable of a maximum energy storage of 400Kj per lap with a maximum 60Kw power boost as per the regulations. The system itself is fairly conventional, using a single liquid cooled brushless direct current motor generator unit (MGU), which operates at around 120 degrees C. Also included in the system is an in house designed KERS Control Unit (KCU) with a similar temperature capability. The battery pack is an ousourced part due to the complex chemistry involved in its development.
The system was first presented at Monza this year to teams and selected media, but the first open showing was a low key corner of the Marelli stand at the recen PMW Expo in Cologne, Germany. The official launch of the system will take place at the PRI show in Orlando next month.
It was developed with a team (many suspect Ferrari) and is fully integrated with that operations powertain and is not an optional extra like some other systems.
