When it Comes to Durability, Our Modules Set The Bar

Ultracapacitor-based energy storage systems are quickly becoming the standard for hybrid buses. The technology improves overall performance by alleviating the battery from many of its responsibilities. The battery is still needed to provide the consistent low energy for long periods of time, while the ultracapacitor handles all of the high current work due to its low resistance. Using this hybridized storage system allows for the strengths and weaknesses of each technology to balance out, resulting in reduced battery size, strong energy-recapture, increased driving range and longer battery life.

Of course the hybrid bus application is a demanding one, with many customers asking for a longer-life product than what is currently offered by our competitors.. We’ve responded by designing our flagship hybrid bus product, the 48 Volt (V) / 165 Farad (F) module, to be the most durable on the market – built to withstand the harshest transportation conditions. Today we’ve released the data from our extensive thermal and vibration durability testing to support our beliefs.
As seen below, when compared to other ultracapacitors on the market, the 48V/165F modules perform at optimal levels in thermal and shock/vibration durability.
Shock/Vibration:

  • Ioxus has passed SAE: J2380, ISO – 16750-3 (Table 12 & 14). This means that the Ioxus products have withstood 96 hours of testing at almost 4 times the g rate as the competitor module.
  • Competitor datasheet only certifies passing the SAE J2380, which is the least invasive of three tests for vibration.

Thermal:
The following chart shows the temperature increase in the modules, when starting the modules at ambient temperature (23°C), while continuously cycling with 120A RMS. The lower temperature increase in the Ioxus modules leads directly to a longer life, as temperature is one of the leading factors in determining the life of an ultracapacitor.

We’re proud of these results and to offer an eight year warranty, which is double that of our competitor’s products. Ioxus listened to its customers to help design these more durable products and will extend these designs to the several major product releases expected in the coming months.

  • IOXUS' uSTART® Receives Edison Award for its Engine Enhancement Innovation

    Ioxus, designers and manufacturers of smart power solutions based on its widely used ultracapacitor technology, today announced that it was named a Bronze winner in the Engine Enhancement category of the 2018 Edison Awards. The announcement was made at the Edison Awards Gala in New York City.

    “We are very proud to have received an internationally recognized Edison Award and to be named a winner alongside companies like Mazda Motor Corporation and CFM International, a joint company of GE and Safran Group, for our engine enhancement achievements,” said Mark McGough, CEO and president of Ioxus, Inc. “This award is recognition that uSTART is proving highly reliable and valuable for fleets in the trucking industry. Being recognized with an Edison Award is one of the highest accolades we can receive in the name of innovation.”

    Inspired by Thomas Edison’s persistence and inventiveness, the Edison Awards are judged by a panel of more than 3,000 leading business executives, including past award winners, academics and leaders in the fields of product development, design and engineering. The judges recognize products as true innovations in their category.

    In addition to the Awards Gala, the annual Edison Awards program encompassed a full-day, “Meet the Innovators Forum” and the, “Innovators’ Showcase,” which offered guests a hands-on experience with read more...
