Corvus Energy AT6500 Module Meets New Standard in Battery Power and Safety

September 06, 2011 by Jeff Shepard

Corvus Energy, the makers of what the company says is a revolutionary lithium-polymer battery, announced that its 6.5 kWh batteries passed the requirements of Lloyd’s Register Type Approval certification tests.

Lloyd’s Register North America, Inc., a member of the Lloyd’s Register Group, assessed the AT6500 module according to the applicable standards and specifications.

"Lloyd’s Register is pleased to provide Type Approval for Corvus Energy’s lithium-polymer battery," said Bud Streeter, Vice President of Lloyd’s Register North America, Inc. and marine manager for Canada. "As an unbiased, third-party organization, we verify that the AT6500 module conforms to the producer’s specification, to national and international standards, and that an appropriate level of product safety is achieved."

An independent accredited laboratory stress tested the AT6500 module for more than three hours in each perpendicular direction. The module performed satisfactorily and did not suffer any damage. It was tested at 4g route mean square levels, exerting four times earth’s gravity, for six hours in all three orientations, as per trucking test specifications. It survived 30g shock, exerting 30 times the earth’s gravity, in every direction, as per U.S. Military test specifications. In every case, the module worked as expected.

"Our module’s energy and safety claims are so much superior to other battery companies that potential customers have been shocked by ’it’s too good to be true’ quality," said Brent Perry, CEO of Corvus Energy. "Lloyd’s Register Type Approval will provide industry-wide confidence in the next generation of batteries."

Corvus Energy’s AT6500 module can withstand being irradiated with high-intensity signals, even with disturbance signals intentionally added to any of the cables. Corvus’ batteries are able to effectively communicate with other batteries in the array and the array controller in conditions to be expected in the marine environment. The battery management system does not produce any harmful noise emissions--radiated or conducted--and it can be used in any vessel without interfering with other equipment.

According to Corvus, the AT6500 can be assembled in packs of up to 1,000V while guaranteeing the safety of the operators and users from high-voltage electricity. The modules, which have the capacity to output sustained power comparable to diesel engines, can survive temperatures of -4 to 140°F.
