CAP-XX develops Stop-Start Automotive Supercapacitor module.
Initial tests increase battery life over 2 times
CAP-XX is pleased to announce that it has developed a supercapacitor module for use in automotive Stop-Start applications, which provides significant performance improvements relative to battery-only systems. This application for CAP-XX's supercapacitor technology represents an important market opportunity, as vehicle manufacturers increasingly adopt Stop-Start systems to reduce vehicle emissions and improve fuel efficiency.
CAP-XX's supercapacitor module removes the dependence of the Stop-Start system on the vehicle's lead-acid battery to supply cranking current to start the engine. CAP-XX has shown that in extended testing its module reduces wear on the battery, which is a common failing of existing systems. Batteries in many of the existing systems may have a functional life of as little as 18 months because of the intensive demands made on the battery. As an additional benefit, the CAP-XX module also provides superior engine starting performance in cold weather, and can be used as an energy store for regenerative braking systems where fitted.
The CAP-XX Stop-Start module is being tested under the New European Drive Cycle standard, and has so far completed 100,000 Stop-Start cycles at room temperature, with minimal wear on battery performance. During the test, the CAP-XX module has maintained the battery voltage above 11.8 volts, providing a very reliable voltage platform for the vehicle electrical systems. Comparative tests of a battery-only system, also at room temperature, show a drop to below 10 volts during the start cycle, after only 44,000 Stop-Start cycles. According to a leading European vehicle manufacturer 10V is regarded as the minimum voltage for reliable Stop-Start vehicle performance.
CAP-XX is now seeking partners to commercialise its technology globally via a Tier-1 automotive component supplier.
In a separate development, ST Micro has launched an integrated supercapacitor driver integrated circuit in collaboration with Murata, CAP-XX's manufacturing partner, and OSRAM. More information is available at www.CAP-XX.com.
Anthony Kongats, CAP-XX Chief Executive said:
"We are delighted with the results of these extended Stop-Start tests, which clearly demonstrate the performance advantages available from a supercapacitor-enhanced system. In particular, the CAP-XX solution addresses the shortcomings in terms of battery life of current generation of battery-only systems. We believe that the automotive sector provides a significant market opportunity for supercapacitors, whilst the ongoing work by Murata reinforces our confidence in mobile handset applications."
