International Submarine Engineering Ltd., Vancouver, British Columbia Canada

Application

Submersible Autonomous Undersea Vehicles (AUVs)

Requirements

The customer needed a precision-performance, long-life, high-density energy source for two unmanned research vessels designed to map the continental shelf positioned above the Arctic Ocean’s underwater mountains. The system would be exposed to extremely cold temperatures and because the vessels are autonomous and completely controlled by battery-powered electronics, a reliable, continuously monitored source of energy was critical.

Solution

Two Onyx™ Lithium Ion Energy Systems were provided to serve as the complete power source for each vessel – including propulsion, navigation, electronics, data collection and communications throughout the undersea mapping exploration. Each system includes our proprietary Battery Management System (BMS) with monitoring features that control all critical functions of the battery’s operation including remote communications to ensure safety and reliability and allow the AUVs to fulfill their scientific mission. The systems have been in operation since September 2009.
