General Motors Becomes First US Automotive OEM to Adopt Ultracapacitors for Start-Stop
September 17, 2015 | Maxwell Technologies
This week Maxwell Technologies announced that Continental Automotive Systems’ Maxwell-powered voltage stabilization system (VSS) will be a standard feature on 2016 Cadillac ATS and CTS sedans and ATS coupes, excluding the ATS-V, CTS-V and CT6 models.
General Motors is the first North American automotive original equipment manufacturer (OEM) to integrate the Continental ultracapacitor-based voltage stabilization as part of the enhanced start-stop system, which lowers fuel costs, improves performance and reduces emissions, delivering an overall superior owner-driver experience.
In start-stop systems, 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 ultracapacitor-based voltage stabilization system implementation provide burst power needed to restart the engine, thus reducing high currents and repeated cycling that can shorten battery life. The voltage stabilization electronic control results in a smooth start, reduced engine vibration and a superior driving experience. Maxwell’s ultracapacitors, in Continental’s VSS design, also serve as an additional power source for stabilizing the vehicle’s electrical system during periods of high power demand.
