AT6700 – Vastly Improved Performance Specifications

Corvus’ rigorous testing program with the Laboratory of Alternative Energy Conversion (LAEC) at Simon Fraser University, one of the preeminent battery testing and research facilities in North America, and its on-going monitoring of its deployed systems has validated improved specifications for the flagship AT6500 lithium ion energy storage product platform.

The Corvus module will now be designated as AT6700 to reflect the validated energy capacity of 6.7kWh.
Richmond, BC – January 20th 2016 – Corvus Energy has validated and is restating the product specifications for its lithium ion battery systems reflecting that the system has double the RMS power capability and substantially more energy capacity than previously reported. As part of its ongoing testing regimen, Corvus worked closely with LAEC and its founder, Dr. Majid Bahrami, at its state-of-the-art testing lab located at Simon Fraser University (SFU) on an extensive series of tests of the performance and characteristics of the AT6500 platform. The testing results are consistent with the performance of our existing installations, which are monitored closely. Corvus has the largest installed base of industrial lithium ion batteries in the maritime industry, including ferries, tugs, offshore supply vessels and port cranes. To recognize these superior specifications, the AT6500 model name will now be revised to AT6700 for the product platform.

Corvus and its cell supplier’s programs of continuous improvement for the AT6500 have played an important role in the improved specification, particularly for Corvus’ liquid cooled module which features the Corvus proprietary active cooling system. A key to getting maximum battery performance is thermal management, which helps the battery system to “keep its cool” during the most demanding operational requirements. Active cooling is controlled by the battery management system (BMS) software that continually measures and reports cell temperatures to an advanced liquid cooling system that significantly lowers operating temperatures, safeguarding the batteries from running too hot. Corvus is continually improving its BMS for new projects and deploying these improvements to its existing customers. The Corvus AT6700 has a 10C peak discharge and 3C indefinite RMS rating. These enhancements show a continuing commitment to product development and a passion for innovation which reinforces and strengthens Corvus’ industry leading position in marine energy storage systems. These improvements also provide our existing customers with the opportunity to get more from their ESS. (Please contact the Corvus service team for more information.)

“We are committed to ceaseless product innovation and testing, inspired by the feedback and requirements of our customers,” said Andrew Morden President & CEO, Corvus Energy. “Actively
listening to our customers regarding their operational needs drove the testing program and the continuous improvement of the AT6500, now available as AT6700. We will continue our industry leading innovation with the introduction of our next generation lithium ESS products later this year. We are the only lithium ion battery company with a substantial base of propulsion systems operating in the field, more than 40 ESSs on vessels and port cranes all over the world, and it is this real world operational intelligence in combination with our rigorous testing program that enables Corvus to specifically design its current and future battery systems to the needs of operators.”

Corvus engineers have designed an ESS tailored to customer specifications using operational load profiles and other requirements without the expense of custom engineering. The only purpose-designed industrial lithium-ion battery system with four marine Type Approvals from Lloyds Register, DNV-GL, ABS and Bureau Veritas (pending). It is scalable from 6.5kWh at 50VDC to multiple megawatt-hours at up to 1100VDC. Most large commercial hybrid and electric vessels employ a Corvus ESS, including the world’s first all-electric ferry, the Norled Ampere, which crosses the Sognefjord, Norway’s largest fjord, 34 times per day, day in and day out.
