NESS Introduces New Ultracapacitor for EVs and HEVs
NESS Corp. (Korea) announced the introduction of their new 2.3V ultracapacitor technology for electric and hybrid-electric vehicle applications. The new NESS ultracapacitor is designed for use in regenerative braking, where it recaptures and recycles energy normally lost through brake-friction heat.
The company reports that the ultracapacitor earned the Chairman's Choice Award for components at the recent POWER 2000 Conference. The 2,500 farad/2.3V ultracapacitor exhibited energy densities of 2.83Wh/kg and 3.74Wh/liter. NESS claims that the device has peak power densities of 5.1kW/kg and 6.7kW/liter, with an almost unlimited number of charges and discharges.
Professor Andrew F. Burke, research engineer and director of the EV Power Systems Laboratory at the Institute of Transportation Studies at UC Davis stated, “The NESS ultracapacitor is the most advanced among the devices I have tested and among those currently available on the market. The NESS device is especially noteworthy in power characteristics arising from exceptionally low ESR, less than 0.3 milliOhms at high current."
The new NESS ultracapacitor is priced according to capacitance sizes and sales volume. For a volume of 100 units with 2,500F capacitance per unit, the price is $200 each.
