PowerModule® battery system obtains Type Approval Certification(TAC) from Bureau Veritas for marine applications

Saint Cyr l’Ecole, France, Dec 2023

Today marks a major step forward for PowerTech Systems, which has obtained marine Type Approval Certification (TAC) for its PowerModule® range of modular batteries.

This international-wide certification, obtained from the Bureau Veritas Marine et Offshore organization, guarantees that the PowerModule complies with several standards, tests and procedures:

  • IEC 62619:2022 (Standard for cell safety and resistance to thermal runaway)
  • IEC 62620:2014 (Lithium ion cell durability standard)
  • Vibration and environmental tests for marine safety
  • Electrical and functional testing
  • ISO 9001 quality system

Battery modules are also tested and certified for safe transport of lithium-ion batteries (UN38.3 standard).

Thanks to its equivalence with other certification bodies (DNV-GL, LOYDS, RINA, etc.), this certification enables PowerModules to be used in all naval electrification projects requiring international marine classification.

Please do not hesitate to contact us for any project requiring certified marine batteries.

Arkema 4: PowerTech Embeds Kynar® Technology in its battery cells

Designed for ocean racing, the trimaran Arkema 4 was launched in September to begin its first trials.

For this new competition trimaran, PowerTech developed very specific servitude batteries, using fluoropolymer separator films in Kynar® technology from the company Arkema.

This new material has very high resistance characteristics, with an extremely low film thickness. The result is the development of even safer battery cells with a 4% reduction in weight.

This battery powers the vital equipment of the racing boat. It is recharged via solar panels.

The “Fludis” boat equipped with PowerRack batteries

Inaugurated in September 2019, the Fludis boat is equipped with PowerTech’s PowerRack Lithium battery system, allowing it to sail 100% electrically in the centre of Paris.

This sustainable urban logistics project is a solution to the difficulties encountered by urban freight transport operators, by offering a warehouse boat capable of handling the stages of route preparation, hosting logistics teams, as well as transporting the bicycle-cargoes used for the last kilometer.


Thanks to the rational use of this “warehouse vessel”, and its independence from loading / unloading infrastructures on the quayside, and the dimensions compatible with the canals, the system can be adapted to each agglomeration crossed by a navigable waterway.

The Fludis boat has been designed to have the lowest possible environmental impact: 100% electric propulsion with batteries. The boat also has a generator onboard to extand the range and to remain autonomous where grid is not available. At the port of Gennevilliers, it can be connected to electricity at the quayside. Consumption is estimated at 70 litres of off-road diesel per day for the trip between Gennevilliers and Paris.

The firm IKEA will benefit from this new type of boat. The Swedish company had opened a depot in February in the port of Gennevilliers to get closer to the capital. Cargo bicycles, which can carry up to 250 kg, will deliver to customers in the central districts (from the 1st to the 7th arrondissements). “30% of orders can be processed,” Ikea explains.

Lithium batteries for the mini transat “La Boulangère”

Mini-Transat “La Boulangère” is a long course of 4050 nautical miles alone, on the smallest offshore racing boats, only 6.50m long, will be done in two stages. The first, departing from La Rochelle on September 22nd 2019, will go to Las Palmas de Gran Canaria located in the Canary Islands. The second of 2700 miles will last around two weeks for the fastest until the final finish in Le Marin en Martinique from mid-November.

For this 2019 vintage, we are accompanying skipper Bastian Oger in his race. Bastian reqyestedus to equip him with PowerBrick batteries because he wanted to save several tens of kilos on board. For the race, every gram counts and a few tens of kilos can make a big advantage.
So we equipped the boat with two PowerBrick 12v-100Ah (one main and one backup) to power all onboard instruments during the race. The service batteries will be recharged with solar panels.
The autonomy tests are very conclusive with twice capacity for roughly half weight. And Bastian is very happy and eager to start, so we are !

Here are some pictures of Bastian aboard his boat. We wish him good luck for the race.
