Class Certified Marine Battery with 15-Year Lifespan
The Dutch company Green Whale Technology has partnered with the Chinese battery manufacturer EVE Energy to provide a fully certified marine battery system.
In a move aimed at both the commercial shipping and yacht markets, two leading companies have signed a strategic partnership to provide high-performance Battery Energy Storage Solutions (BESS) to a global customer base.
As yachts move more towards electric propulsion and generator-free renewable energy systems for hotel loads, so the need for every greater storage capacity has become more important. This emerging market for large storage capacity has been recognised by two leading companies, who have decided to share their expertise. The lithium batteries at the heart of the system will be provided by the Chinese giant EVE Energy, and the expertise for the marine installation, engineering and servicing will come from the Dutch company Green Whale Technology.
The two companies are no strangers to building BESS to class approval standards and have already delivered the first BV-classed (Bureau Veritas) marine battery container to be built in Asia.
The new BESS developed by the partnership is said to have several key advantages for creating more cost effective and dependable batteries with a longer lifespan. In a joint statement, the two companies said there are three ‘eye-catching’ main characteristics.
“First, thanks to EVE’s active balancing technology, these systems deliver a lifetime of up to 15 years,” the authors state. “This surpasses any LFP (Lithium Iron Phosphate) systems in the market today, and significantly reduces the total cost of ownership. Second, the high C-rate (charge/discharge factor) maritime battery market was long dominated by NMC (lithium Nickel Manganese Cobalt) cell-based systems. EVE, however, is currently the only supplier in the world offering 3C continuous LFP marine batteries, offering a longer lifetime than NMC-based system in many application scenarios. Third, the alliance’s massive production capability, advanced LFP chemistry technology, maritime experience, cost advantages, data safety, and global service capacity shows this solution’s potential to be a game-changer in the market.”
Another selling point is how Green Whale Technology is establishing a Netherlands-based cloud service platform. The company says this will guarantee local data compliance, digital security, and mitigate geopolitical risks. Spare parts storage in Norway and the Netherlands should further strengthen timely after-sales support, while joint R&D initiatives will be used to continue innovation.
Providing battery systems on a commercial maritime scale will require a large capacity operation, but this is where the partnership should prove very useful. EVE Energy is one of the world’s largest battery manufacturers (cells and systems) and can leverage its huge ESS system factory capacity of over 10 MWh per day to ensure scalability and timely delivery. In addition, the 3C marine battery system is priced below US$300 per kWh, which the company says is unique in the current market.
The new BESS has already been certified by DNV, BV, ABS, NK, and CCS. Other classification societies are currently in the process of certification. The advanced three-layer BMS architecture has been customised for maritime applications and is certified to IEC62477 standards. This is said to ensure redundancy, high EMI (electro-magnetic interference) resistance, and reliable performance. The alliance is currently developing a new battery product based on two new types of battery cells, which is expected to come into the market in 2026.
Godfrey Wang, CEO of Green Whale Technology B.V, said “GWT is very proud of this partnership, especially because we are a young company. This really strengthens our ability to provide lifecycle solutions to global customers. I would like to thank the entire EVE team for their trust and seamless collaboration, and we look forward to growing together.”
