Our Homebase for Innovative Solutions

Our Vision – From Nature We Learn

Sustainable and stable energy systems combine local energy conversion and local energy storage.

Electric energy is
clean, efficient and convertible to any other form of energy. It has become part of our life.
Mobility is converting from fossil fuel to electricity and simultaneously electric energy generation will convert from fossil and nuclear to renewable energies. Accordingly electric energy storage is inevitable.

Salt batteries are a sustainable way of electric energy storage with a huge potential for improvements.

BATTERY CONSULT has the know-how and passion to continuously improve this technology with ideas, concepts and R&D for the benefit of our customers.

Our Team

Our team of engineers and technicians has over 30 years’ industrial experience in advanced sodium-nickel-chloride (NaNiCl2) batteries for use in energy management, storage and automotive applications.

Together we are Battery Consult AG
