Kinetic Energy Recovery Systems
The wide experience in mechanically coupled flywheel technology at DTI has resulted in the development of Brake Energy Recovery Systems that make use of medium speed flywheel technology. Using this technology in combination with a compact electric machine, enables a cost-effective hybrid drivetrain structure.
Using flywheel technology is an effective and low-cost way to enable basic hybrid functions such as brake energy recovery, engine assist and engine start/stop. It substantially reduces the need for batteries, inverters, cabling, and electric machine power to realize generation, storage and re-motoring of the vehicle’s brake energy. The structure can be mated with any type of transmission (MT, AMT,
Powershift AMT, AT,
CVT,
DCT).
An interesting combination occurs when combining the flywheel energy recovery system with a CVT as main transmission. In such case there is actually no need for any electrical system, rendering the most cost-effective hybrid suitable for main stream applications.
Where A segments cars already have sufficiently low carbon emissions, the (price sensitive) B/C segments can easily and economically complement the future fleet CO2 regulations of 95 g/km by adopting this low-cost energy recovery system. For higher segments cars, full electric medium or full hybrids appear to be the best match between on-cost and added value.
