Lithium-ion (Li-ion) batteries are largely produced for high-tech professional applications and are easily integrated due to their small size. The technology has proven its high reliability through many years of subsea operation as well as substantial operational experience from other similar critical applications. Li-ion batteries provide exceptionally long life and maintenance free technology, allowing for total lower life-cycle cost.
FMC have developed a Battery Management System (BMS) dedicated to the application. Features in this system allow users to manage: power flow in the systems; charging strategies; monitoring of voltage, current and temperature; cell balancing and redundancy switching with a CAN interface.
