Ultracapacitor pioneer Ioxus has announced the launch of a series of module systems for a single-piece extruded housing for use with all of its axial ultracapacitors.

The iMOD X-Series allows for every cell to be in thermal contact with the outside of the housing, allowing for even heating and cooling, as well as reduced heat generation, which promotes even aging of the cells, to create a longer-lasting, more reliable product.

Features of the iMOD X-Series include:

• End-To-End Cell Laser Welding: Reduces the number of bus bars, which in turn lowers cost and module equivalent series resistance (ESR).
• Voltage Balancing: iMOD X-Series offers true voltage balancing to extend the life of each cell, unlike other ultracapacitor manufacturers that offer basic voltage clamping.
• Front-facing Terminals: Allows for the use of simple bus bars that clean up system layout and eliminates cables that crisscross in the system.
• Structural Thermal Bridges: Maximizes and balances thermal transfer from the cells to the housing while adding mechanical structure and robustness.
• Customizable End Plates: Allows for virtually any mounting configuration.
• Simple Sealing: Requires only two seal points compared to competitors’ five.

Ioxus customer Dynex Semiconductor selected the iMOD X-Series for its compact construction and lower mounting costs for long strings of capacitors. “We conducted head-to-head testing between the Ioxus 3000 Farad cells and those from other suppliers,” said Dynex’s Bill McGhier. “Following significant levels of long-term cycling performance testing, Ioxus ultracapacitors demonstrated the lowest drift in ESR and capacitance compared to the competition. We have found the Ioxus team to be reactive and cognizant of some customizable features required by our high-voltage, high-isolation system. As a result, Dynex has been able to reduce the complete system footprint by 50 percent.”

“By sharing common components in our modules, we’ve designed ultracapacitors that can easily fit into standard racks with no shelving required and at 50 percent less volume than our competitors,” said Ioxus CTO Ken Rudisuela.
