In comparison with the hybrid technology of production vehicles, the concepts for motor racing are considerably more powerful and compact.

"Max­imum power" and "optimum packaging" have long been watchwords of race engineering, and they apply to the advent of KERS (kinetic energy recovery systems) technology, which is becoming a part of motorsports requirements and demonstrates the spread of hybrid applications.

Now, Bosch Motorsport has announced that it is developing a modular KERS kit designed and developed to cover requirements from Formula One to other racing 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," said Klaus Böttcher, Director of Bosch Motorsport. "We are holding discussions with many teams from various racing series."

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.

Hybrid systems by Bosch Motorsport comprise a battery, electric motor, and KERS controller, which contains the power electronics, battery management, and the management system for hybrid and engine functions. A lithium-ion battery with scalable capacity or a flywheel can be used for storing energy.

The flywheel system stores up to 750 kJ of energy. The electric motors have a mass between 4 and 8 kg (8.8 and 17.6 lb), with a maximum power of 60 kW.

Bosch Motorsport states that, because of its modular structure, its KERS solution can be put together individually—in terms of weight, robustness, and performance—to suit the requirements of particular types of race cars. The company adds that it has experience of technology support and integration knowledge for many race series.

Bosch Motorsport Service is part of Bosch Engineering GmbH, which specializes in engineering services. The company first became involved in motorsports in 1903. The Bosch Group has been involved with hybrid technologies for more than 30 years and has comprehensive specialist knowledge in battery, electrical drive, brake management systems and processes, together with engine management and transmission control.
