Tesvolt Ocean’s ‘Kaptein’ power storage offers high energy density, fast charging

A Germany-based company has introduced a battery system at the SMM trade fair in Hamburg that will enable significantly more vessels in the maritime and inland shipping industry to be equipped with clean e-drives for the first time.

Tesvolt Ocean’s battery modules can be installed individually and at any angle of inclination, wherever there is space for them in the ship.

The company maintains that vibration-resistant storage modules can also be installed on the floor and walked on. Ships have often not had enough space for battery storage systems with sufficient capacity, until now.

The new “Kaptein Series” power storage system features further unique characteristics, as a result of its disruptive technology: from the lightest weight to the highest energy density to the fastest charging capability.

Best-in-class storage system

“We’re entering the market with a best-in-class storage system , offering a technological solution for the biggest pain points of ship owners, system integrators, and shipyards,” explained Kent Thoresen, CTO of TESVOLT OCEAN.

“The range of ships with electric propulsion , for instance, is still a problem for many owners. Ship spaces are often cramped, so not enough battery modules can be accommodated to achieve the desired range. At 246 Wh per liter, our new Kaptein system has the highest energy density on the market to date, meaning despite its high capacity it takes up very little space.”

Kaptein storage system offers the highest continuous C-rate

Most batteries approved for use in shipping did not even have a continuous C-rate of 2 C. At 4 C, the “Kaptein” storage system offers the highest continuous C-rate available in the maritime industry to date. This means significantly shorter charging times for ship owners, according to the company.

“We spent three years speaking intensively with customers in six focus groups about what they need. That’s why Kaptein fits their needs so well. It solves real problems in e-propulsion for ships,” added Kilian Hoffmann, CCO at TESVOLT OCEAN.

“We’ve already had a huge number of inquiries about the new battery system.”

Cost-efficient compared to others

“Every customer has different goals. That’s why we always tailor our battery system precisely to the individual customer. Kaptein is not an off-the-shelf product. But due to its special cell-to-module design, it’s exceptionally cost-efficient compared to the rest of the market,” said Øystein Kjæreng, CEO von TESVOLT OCEAN.

“We’re a one-stop shop, offering planning, installation, and commissioning as well as monitoring, maintenance, and recycling. We want to make a significant contribution with this new product toward accelerating the equipping of shipping with clean e-drives — as simply and cost-effectively as possible.”
