Accelerate the worldwide adoption of electric vehicles.

What sets us apart

Our technology can be adapted to any cell format and electrochemistry.

We excel in manufacturing high-performance battery packs quickly and with a high level of quality and traceability.

Our clients appreciate our agility and technological expertise.

Our DNA is based on our high responsiveness and our ability to meet the most demanding industrial requirements: rail, aerospace, marine, and defense.

It is up to the client to specify their needs or to rely on our extensive experience to obtain the best configuration based on the use of the battery pack.

Extended lifespan: reduced environmental impact

Extreme temperature

-50°C / +80°C

Maximum safety

No thermal runaway propagation. The 10,000 hours of internal testing prove that our immersion cooling technology prevents thermal runaway propagation, even with passive cooling. We have demonstrated that when a cell undergoes a nail penetration test (NPT), it reaches 400°C while adjacent cells only reach 100°C.

High power

Very high-power density: Our patented technology cools a surface up to 14× larger. This guarantees a temperature gradient 4× better than traditional cooling systems (cold plates).

Ultra-fast charging: our algorithms control the anode potential of the batteries to prevent degradation in real-time. This allows us to reduce the charging time to 10 minutes

Extended lifespan

Reduced environmental impact
