From June 18 to 22, I will be in Mainz, Germany at the Advanced Automotive Batteries Conference (AABC), a show that examines solutions to the evolving technological needs of European automakers. I’ll be discussing how supercapacitors can solve one of the problems facing automakers: affordable, high performance, reliable energy storage systems for micro hybrids. While batteries fall short in some of these areas, auto manufacturers can improve their applications by implementing ultracapacitors.

As part of the capacitor-focused ECCAP Symposium seminar on Wednesday, June 20, I will address the new vehicle applications resulting from the increased micro hybrid adoption and how supercapacitors can help achieve these new requirements. Specifically, the efficiency of these vehicles is greatly limited by the poor charge acceptance of lead-acid batteries, in particular at cold temperatures, which prevents the occurrence of many start-stop events. However, manufacturers can avoid this by implementing supercapacitors alongside batteries.

In micro hybrids, a normal combustion engine is turned off while the driver is stopped at a light or stuck in traffic. Before the driver even notices, the engine is quickly restarted upon acceleration. Supercapacitors are an ideal solution because they can charge and discharge energy rapidly while handling high charge/discharge cycles. When combined with a battery, supercapacitors enhance application performance by providing a large amount of support for the system. Whereas battery-powered start-stop systems often perform poorly under cold temperatures due to battery limitations, supercapacitors have an operating range of -40 °C to +65 °C, ensuring that systems work properly even under extreme conditions.

If you’re at the show, be sure to register on-site for the ECCAP Symposium on Wednesday, June 20 at 8:45 a.m. CEST. You’ll hear all about how supercapacitors are transforming micro hybrids into better, more efficient applications.

  • uSTART® Lead-Free Replacement for Truck Batteries

    ONEONTA, N.Y.Jan. 9, 2019 /PRNewswire/ -- Ioxus uSTART® has received two fleet industry awards for sustainability by eliminating lead-acid batteries with its ultracapacitor-based, drop-in battery replacement.

    "With uSTART, fleets not only realize the benefits of improved starting reliability, there are equally important and real sustainability improvements from lead waste reduction," said Chad Hall, executive vice president and co-founder of Ioxus. "By replacing one of the batteries on a vehicle with a uSTART module, up to 15 fewer batteries are needed over the lifetime of the vehicle. This translates into 1,000 pounds of lead that will never need to be disposed of or allowed to affect groundwater."

    EU legislation on batteries is embodied in the European Battery Directive.  Its objective is to contribute to the preservation and improvement of environmental quality by minimizing the negative impact of batteries and battery waste.  As these preservation efforts expand, sustainable technologies develop to manage and mitigate these risks.

    Replacing a lead-acid battery with uSTART in a typical commercial vehicle creates measurable environmental benefits:
