Waterproofing Power Resistance

Batteries are playing an increasingly crucial role in the maritime sector, providing solutions for more efficient, quieter and more environmentally friendly navigation.

Currently, lead batteries represent a huge part of boats and marine motorized vehicles power supply. However, it involves the drawback of heaviness in terms of weight and environment impact.

TYVA Energie’s lithium batteries perfectly fit the same role as lead batteries without all the disadvantages it implies while being waterproof and resistant to cover your marine requirements.

Applications examples:

Electric boat
Recreational vehicle
Beaconing buoys
Data buoys
Remotely operated underwater vehicle (ROV)

Batteries for the propulsion of leisure or industrial vessels

Fully electric boats: An increasing number of vessels, particularly small pleasure boats, short-distance ferries, sightseeing boats, and water taxis, are powered solely by battery-powered electric motors. This allows for a quiet, low-emissions, and less vibration-prone journey.
Hybrid boats: These vessels combine electric propulsion with a combustion engine (diesel or gasoline). The batteries can be used to:
- Provide propulsion at low speeds or in sensitive areas (ports, protected areas) in 100% electric mode.
- Provide a power boost during maneuvers or acceleration.
- Optimize the combustion engine by allowing it to operate at its optimal speed to recharge the batteries, thus reducing fuel consumption and emissions.
- Use hydrogen generators (fuel cells) in combination with batteries for electro-hydrogen propulsion, offering increased range and zero emissions.

Service batteries
(or cycling/deep discharge)

They power all onboard electrical equipment not related to propulsion.

Lighting (interior and exterior).
Navigation systems (GPS, depth sounders, radar, electronic charts).
Communications devices (VHF, radios).
Comfort equipment (refrigerators, freezers, microwaves, washing machines, air conditioning, watermakers).
Entertainment systems (TV, audio).
Pumps (bilge, freshwater).
Electric winches (anchor windlasses).
Auxiliary engines (trolling motors).
Security systems (alarms, sensors).

Energy storage for maritime power systems

Solar or wind systems: Batteries store the energy produced by the solar panels or wind turbines installed on the boat, allowing equipment to be powered even without the engine running or access to the dock.
Backup power: They can serve as a backup power source in the event of a failure of the main power system.

Oceanographic battery systems

Underwater robots and aquatic drones: Compact, powerful batteries power these devices for exploration, surveillance, or research.
Diving equipment: Some diving lights or thrusters use rechargeable batteries.
Dynamic positioning (DP) systems: On work vessels, batteries can provide additional power to maintain precise positioning.

Advantages of our lithium batteries ranges

Modular and compact batteries

Our batteries’ ranges adjust to your needs. Our Moduloo 3D range offers you the flexibily to build a quick and economic 3-dimensions solution. Our Moduloo Ax range gives you the possibility to connect several batteries in series or parallel thanks to its ultra compact designs.

Battery reconditioning

Since TYVA Energie’s creation in 2013, our entire range of batteries includes the TYVA Refill cell replacement patented technology. Thereby, every single battery component can be reused to guarantee products with a constant energy level as well as infinite life batteries. We focus on cells conversion and recycling, mostly by using NMC chemistry, to promote the circular economy and thus reduce our carbon footprint to its maximum.

Lightweight batteries with high energy density

Moduloo Ax and Flat & Kube lithium batteries’ core packs are the most compact and lightest on the market. It is possible thanks to their thin format and high energy density, only 245 Wh/kg for a battery which makes them the most powerful lightweight batteries.

The true price of Made in France

Our standard modular systems allows you to piece together series or parallel assemblies in a short timeframe without any development costs nor certificate. Our TYVA Refill solution guarantees you to save money in the long run. Furthermore, TYVA Energie offers the lightest and most compact lithium batteries on the market with an outstanding energy density of 245 Wh/kg only. It allows you to gain autonomy while saving energy.

Fire protection technology

TYVA Energie has elaborated the TYVA Pyro Protection solution (TPP) created by our Engineers to prevent fire propagation in our batteries. Cells are isolated from one another if an overheating occurs thanks to the presence of this technology in our core packs. Thus fire propagation is avoided and we limit the risks of accidents related to lithium.

"Power" and "Energy" ranges

Our technology allows us to realise 2 versions of lithium batteries’ core packs: the high density “Energy” version and the “Power” version with high permanent discharge rates (up to 10C). Our multi-chemistry internal modular platform based on standard 18650 cells permits to integrate various chemistries available on the market: LFP and NMC.
