Delphi's Energen family of energy-management systems can provide additional electrical power for a range of functions.
These include: a stop-start system that shuts off the engine when it is idling, then restarts the engine through an accessory belt when the driver wants to move again; 42-volt support for the next generation of electrical systems; and electric power assist on hybrid vehicles.
The Energen Hybrid Electric Propulsion System was used on the Dodge ESX3 concept car shown early this year in the USA. The hybrid ESX3 featured a high-energy density, air-cooled, embedded permanent-magnet motor with an integrated power electronics system.
An Energen stop-start system is due to be fitted to a production car in Europe next year.
The systems can improve fuel economy by more than 5 percent in small-engined vehicles during city driving, according to Delphi.
The systems also allow quieter engine starts, smoother acceleration, and increased functionality using various electronic and electrical features. The Energen system in the Dodge ESX3 helped the vehicle achieve fuel efficiency of 3.3 liters per 100km.
