WATTALPS

WATTALPS designs and manufactures in France high-performance Li-Ion batteries, using a patented immersion cooling technology.

This technology enables to push further the limits of classical li-ion batteries, by increasing their performance, their life and their safety. In addition to outstanding thermal management efficiency, immersion cooling provides a high level of passive safety against thermal runaway propagation.

Thanks to our BMS, with hardware and software designed in-house, WATTALPS guarantees best-in-class functional safety up to ASIL C. In addition to outstanding safety management by our BMS, our immersion cooling architecture provides a high level of passive safety against thermal runaway propagation.
The dielectric fluid used for WATTALPS batteries is biodegradable, non-toxic and non-flammable.

The modular design of the packs allows for a fast integration phase and very compact solutions with high energy density and extreme power output.
The WATTALPS solutions are thus available in 3 families, adapted to the specific applications of our customers, favoring either the extreme compactness of the High Energy packs, or the possibility of repeated fast charging for the Long Life packs, or the ability to withstand very high current peaks for the Power packs, which are particularly well suited to machines hybridization.

WATTALPS batteries, including connections, are IP67 / IP69K rated.

WATTALPS batteries are certified according to IEC62619 and ISO26262 ASIL B/C, and have passed all tests for R10; UN38.3 and R100rev.3.
