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.

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.

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.

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.

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.
