GM Is ‘First U.S. Automotive OEM to Adopt Ultracapacitors for Start-Stop’

General Motors will ship 2016 Cadillac ATS and CTS sedans and ATS coupes with a Maxwell Technologies ultracapacitor start-stop system as standard, Maxwell said today. The Maxwell ultracaps power VSS/voltage stabilization systems by Continental Automotive.

Maxwell’s ultracapacitor-based start-stop system will be a standard feature on 2016 Cadillac ATS and CTS sedans and ATS coupes, the company said today.

In start-stop systems, Maxwell explains, the internal combustion engine is shut off when the driver stops “and the engine is seamlessly restarted when the driver accelerates, which lowers emissions and improves fuel economy.”

Battery-based start-stop systems augmented with an ultracap-based voltage stabilization system provide “burst power” to restart the engine, thus reducing high currents and repeated cycling that can shorten battery life.

‘An Affordable Option’

“The voltage stabilization electronic control results in a smooth start, reduced engine vibration and a superior driving experience,” Maxwell adds, noting that in Continental’s VSS design, its ultracaps serve too as a power source for stabilizing the vehicle’s electrical system.

“Automotive manufacturers around the world are seeking new ways to improve the performance of their cars while satisfying consumer demands for fuel efficiency,” Jon Buckles, program manager for hybrid electric vehicles at Continental, says in Maxwell’s announcement.

“Continental’s voltage stabilization system uses Maxwell’s ultracapacitors as an affordable option for automakers to create a more positive driving experience for their customers,” Buckles said.

“GM’s selection of Continental’s Maxwell-powered VSS is a further affirmation of our ultracapacitor capability for varying applications as the automotive industry continues down its path of vehicle electrification,” said Maxwell CEO Franz Fink.
