Since August 2005, AccelRate has tested its patented charging algorithm with 60Ah cylindrical lithium-ion batteries provided by a leading designer and manufacturer of lithium ion rechargeable batteries. These batteries are designed for high-energy applications including military, stationary and transportation use.
Early test results demonstrate the ability of AccelRate's patented technology to safely reduce the lithium-ion battery's charge time from two hours to less than one-half hour -- a decrease of approximately 75% -- without detrimental battery temperature escalation. This feature should allow more robust battery performance and greatly reduce the concern about heat generation for high charge rate applications.
In the past, lithium-ion batteries could not be fast-charged due to heat escalation while charging and typically needed from two to five hours to fully charge. Using AccelRate's "High-Speed" battery charging technology, current lithium-ion cells can be fully charged in 30 minutes or less and based on further investigation, should ultimately maximize the cell life of the lithium-ion battery.
"Based on our early results, we are confident that AccelRate technology can and will reduce the charge time of advanced lithium batteries, similar to its validated 80% reduced charge time with conventional lead acid, nickel metal hydride and nickel cadmium batteries," said Reimar Koch, President and CEO of AccelRate Power Systems. "This is an important milestone on our technology path which we will now feed into our product development activities to take advantage of the emerging market opportunities for lithium batteries."
Today, lithium-ion is the fastest growing battery and seen by many as the most promising battery chemistry for a variety of applications due to its leading energy-to-weight ratios, lack of memory effect and slow loss of charge when not in use. These benefits make lithium-ion the ideal battery for portable and transportation applications.
AccelRate's proprietary charging technology functions effectively with batteries of all conventional chemistries and sizes in industrial, portable, power tool, military and transportation applications. AccelRate's technology provides customers with up to 80% decreased charging time, increased battery lifetime due to improved heat management, and decreased energy use.
Industrial chargers incorporating AccelRate's "High-Speed" lead-acid battery charging technology are currently available in North America through Hawker Powersource at www.hawkerpowersource.com or through AccelRate Power Systems at www.accelrate.com.
