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.

World premiere: “Ducasse sur Seine”, the first 100% Electric Michelin Starred restaurant boat, equipped with the PowerRack battery system

PowerTech Systems is pleased to announce that it is equipping the “Ducasse sur Seine”, 100% electric boat with its  PowerRack®  modular lithium battery system.

This 100% electric boat (propulsion, on-board equipment, kitchens, etc.) is powered entirely by our Lithium Iron Phosphate batteries, representing a stored energy of 720 kWh divided into two totally independent PowerRack banks.

The PowerRack battery system, certified by Bureau Veritas in early 2018, consists of 24 cabinets of 30kWh in 700V DC, connected in parallel. These batteries represent a weight of about 9 tons on board. This cabinet system limits floor space and allows energy to be stacked over the entire height of the hull, making the installation compact and integrated into the boat.

The “Ducasse sur Seine” has been in production since September 10, 2018. It delights the taste buds of its passengers twice a day (lunch and dinner), every day of the week. The trip to the heart of Paris is done without vibrations, silently, and without any pollution.

The official inauguration of the new vessel took place on 25 September 2018 in the presence of Mrs Anne Hidalgo, Mayor of Paris, and other personalities.
