Charged EVs | WATTALPS offers batteries with immersion cooling for demanding commercial EV applications

French battery manufacturer WATTALPS is offering batteries based on immersion cooling technology.

All cells and busbars in the company’s batteries are fully immersed in an electrically isolating dielectric fluid that is non-flammable, non-toxic and biodegradable. The batteries deliver passive safety thanks to technology that prevents propagation of cell thermal runaway, and active safety through the battery management system, according to the company.

The battery specifications range from 48-800 V and from 10-500 kWh or more, and incorporate native IP67 and IP69K design. Thermal management enables repeated fast charges and high current peaks—even in harsh conditions including temperatures from -20° C to +50° C as well as dust, shock, water and vibrations.

WATTALPS is an IEC 62619 and ISO 26262 up to ASIL C-certified provider and works with customers to design battery packs to meet their needs.

“The rectangular block shape modules have the smallest form factor on the market and enable compact battery packs with quick integration,” according to the company.
