WATTALPS is tackling the challenges of electrifying all types of heavy equipment head on. With battery systems designed to operate in all conditions, the company promises faster charging and more available power. The key is its groundbreaking modular immersion-cooled lithium-ion batteries built on a technology honed over a decade of research and development at the CEA. ​

When it comes to batteries, the industrial equipment and agricultural machinery markets are vastly untapped, with only 0.1% of the installed base currently running on electricity. With environmental and energy imperatives now top-of-mind in many industries, WATTALPS offers a viable alternative to diesel with its novel approach to the thermal management of batteries.

The company’s first battery, manufactured in small and medium-sized batches, offers excellent safety and performance. Plus, with development costs 20 times lower than for conventional high-performance batteries, WATTALPS’ batteries are economically competitive. The batteries are also reusable and recyclable, two factors that align closely with energy transition objectives.

The €11 million in capital came from new investors Supernova Invest, Ring Capital, Move Energy, and CASRA Capital, who have now joined the company’s existing investors EIT InnoEnergy, Eximium, and the European Innovation Council’s EIC Fund. The influx of funds will position WATTALPS to roll out an aggressive strategy that spans manufacturing—with a planned eight-fold increase in capacity—, productivity and cost improvements to its current modular lithium-ion batteries, new product development, and international growth. ​
