High voltage batteries for maritime applications

The generation of electric power in maritime and mobile applications comprises the use of multiple mechanical, electrochemical and electronic components and systems that make it a complex undertaking and an interesting system integration problem. The integration of such systems is often complicated although equally complex systems have been integrated successfully into smaller, higher powered single dasiaall-in-one-boxpsila devices. The electrochemical part of the system generally consists of lead-acid batteries commonly found in such vessels; the purpose of this paper is to show the possibility of reducing the volume and weight of the batteries for this type of system by the means of using high voltage hybrid battery packs, which will comprise lithium-ion batteries, supercapacitors, dc/dc converters and protection electronics for monitoring.
