Corvus Energy’s 6.5 kWh lithium-polymer batteries just passed the requirements of Lloyd’s Register Type Approval certification tests. Lloyd’s Register North America, Inc., a firm that assesses business processes and products to internationally recognized standards, reported that the AT6500 module meets national and international standards, and it has an appropriate level of product safety. It is one of the world’s first batteries, intended for propulsion power to receive Lloyd’s Register Type Approval.
AT6500 modules are currently providing diesel-engine-scale power to the Canadian Space Agency’s brand-new electric lunar rover, food star Russ Kremer’s first-ever 100% off-grid, zero-waste pork processing plant, off-grid communities, and a refitted Foss Maritime tugboat that’s drastically reducing its diesel usage and emissions output.
The savings are considerable. Long-haul trucks, for example, idle an average of 2,000 hours per year, consuming one gallon of fuel per hour. With Corvus batteries, long-haul trucks would reduce fuel consumption by 2,000 gallons (more than $8,000) annually.
The AT6500 is built around a new and highly stable nickel-manganese-cobalt-based Dow Kokam cell and is designed for the needs of heavy industry. The batteries are up to 10 times more powerful than lead-acid batteries and are, at minimum, 22% more powerful than current alternative lithium-polymer competitors. The batteries are built to handle the world’s most hazardous ocean conditions. Fully waterproof to 1 atmosphere, they can operate from -4 to 140°F and feature standard shock ratings at 30G and vibration ratings of 8G aboard current vessels.
A battery management system constantly monitors each module. They’re sealed in purpose-built aluminum casings, water and tamper proof, and they boast of triple-redundant safety features. Each cell is individually fused to eliminate the remote chance of thermal runaway and, given their low impedance, the batteries are an impressively 99% efficient in the transfer of energy, and require no external ventilation.
The batteries are minimizing diesel consumption on a global scale through hybrid and full-electric propulsion systems for heavy polluters, such as tugboats and gantry cranes, and they provide instant energy storage and distribution solutions for grid systems, remote communities, wind farms, and other renewable energy sources.
