Bosch Motorsport is developing a Kinetic Energy Recovery System (KERS) for use in motor racing. The modular KERS kit covers racing requirements from Formula 1 to series such as the DTM or 24-hour races. Bosch presented the variable, modular KERS kit at the Professional MotorSport World Expo 2008 (11-13 November) in Cologne, Germany.
Hybrid systems by Bosch Motorsport comprise an energy storage system, the electric motor, and the KERS controller, containing the power electronic, battery management, and management system for hybrid and engine functions.

A lithium-ion battery with scalable capacity or a flywheel energy storage device is used for storing energy. The latter can store up to 750 kilojoules (0.208 kWh) of energy. The electric motors weigh between four and eight kilograms with a maximum power level of 60 kW.
Due to its modular structure, KERS from Bosch can be put together individually in terms of weight, robustness, and performance to suit the requirements of the respective race series.
In comparison with the hybrid technology of production vehicles, the concepts for motor racing are considerably more powerful, and at the same time more compact. We are already holding discussions with many teams from various racing series.—Klaus Böttcher, director Bosch Motorsport
Depending on the specific design, the systems are intended to allow for more overtaking maneuvers using additional power that can be called upon temporarily or even to reduce the number of refueling stops by cutting consumption.
Bosch Motorsport Service is part of the subsidiary Bosch Engineering GmbH, which specializes in engineering services.
The Bosch Group offers a range of electri and hydraulic hybrid systems for commercial and light-duty applications. (Earlier post.)
