Continental AG, has selected Maxwell Technologies’ BOOSTCAP ultracapacitors as the energy storage element of a voltage stabilization system (VSS) it has developed for automobiles. The VSS stabilizes the auto’s electrical system and supports stop-start functionality for improved fuel efficiency and reduced emissions.
Continental has advised the company to prepare for delivery of initial series production volumes of BOOSTCAP cells for new car models starting in 2010, according to David Schramm, Maxwell’s president and chief executive officer.
Stop-start systems reduce fuel consumption and emissions by shutting off the car’s internal combustion engine as the vehicle slows and seamlessly restarting the engine when the driver engages the clutch or touches the accelerator. In the VSS system, the ultracapacitor module provides burst power to re-start the engine, relieving the car’s battery of high currents and repeated cycling that can shorten battery life. It also provides a reservoir of power to ensure stable functioning of the vehicle’s electrical system when multiple power demands tax the system.
Schramm said that Maxwell is also working with other Tier 1 suppliers, automakers and heavy vehicle OEMs on ultracapacitor-based solutions for other electrical system applications and various hybrid and electric drive systems.
