Battery Charging Standards in the Maritime industry

by Aug 19, 2022

The Charging Interface Initiative (CharIN) e.V. and the Maritime Battery Forum (MBF) have agreed to work together to promote battery charging standards in the shipping industry. CharIN’s expertise in charging infrastructure combined with a global network of marine battery providers within MBF will accelerate the deployment of onboard batteries with megawatt (MW) scale charging standards. CharIN – The Charging Interface Initiative e.V. is a non-profit organization with over 280 members worldwide and is open to all companies dealing with e-mobility worldwide. Under the umbrella of CharIN, car manufacturers, charging station manufacturers, component suppliers, energy suppliers, network operators and many other industry stakeholders are working together to ensure that vehicles, chargers, and software systems work together to create an interoperable user experience. We are making further progress toward more efficient charging. Reliable. light and smooth.
Around 600 ships in the world rely on batteries for propulsion. There is an increasing demand for the use of high-capacity batteries. Total installed battery capacity on board of ships annually decreased in 2021 but is expected to increase again in 2022 to at least about 180 MW. Approximately 25% of battery-powered ships are currently solely battery-powered, 25% are plug-in hybrids, and 50% are hybrids without the ability to be charged by a shore-based charging system. The average on-board battery capacity in 2022 is 1.2 MWh, and the charging power required by ships is often in the MW range. The megawatt charging system ‘MCS’ is expected to accelerate the adoption of MW charging in the maritime sector and increase the number of plug-in hybrids compared to hybrid vessels. This is an important step towards reducing emissions in and around ports.
Advantages of MCS (Megawatt charging system) are that it will promote convergence to limited number of standards, help with the adoption of containerized ships along with identification of interface between battery containers and ships and make it easier for service providers and clients to better understand the concept of vessel charging.
Major players having a key role in the development ABB, Cavotec & Plug.
The development of megawatt charging system for electric vessels can prove to be a breakthrough in the marine electrification projects. It will air in setting some sort of standards for vessel charging which will enable the widespread adoption of vessel charging by ports all around the globe. In addition to this a uniform charging system for electric vessels will help with the training of staff in a much more efficient manner.
