ONEONTA, N.Y.--(BUSINESS WIRE)--Ioxus, a manufacturer of premium performance ultracapacitor technology for use in transportation, industrial and energy applications, today announced results of an extensive durability test of its flagship hybrid bus product, the 48 Volt (V) / 165 Farad (F) module. The data reaffirms Ioxus’ belief that its modules significantly outpace competitors including Maxwell, in thermal and vibration durability testing.
Customers have been asking us for a longer-life product than what is currently offered by our competitor, so we have responded by designing these more durable products, and will extend these designs with several more major product releases in upcoming months. Ioxus modules meet the harshest demands of transportation applications.
When compared to other ultracapacitors on the market, the 48V/165F modules perform at optimal levels in durability. Results include:
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 Maxwell module.
- Maxwell datasheet only certifies passing the SAE J2380, which is the least invasive of three tests for vibration.
| Standard | SAE 2380 | ISO 16750-3 Table 12 | ISO 16750-3 Table 14 | |||||||||
| Frequency (Hz) | 10-200 | 10-2000 | 10-2000 | |||||||||
| Vertical Max RMS acceleration (g) | 1.90 | 5.90 | 2.17 | |||||||||
| Longitudinal Max RMS acceleration (g) | 1.50 | 5.90 | 1.20 | |||||||||
| Lateral Max RMS acceleration (g) | 1.50 | 5.90 | 1.34 | |||||||||
| Total Test Time (hrs.) | 92.6 | 96 | 96 | |||||||||

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.
