From a family enterprise to global battery expertise
Over 30 years of battery innovation and custom engineering
- Enix Power Solutions is part of the Upergy group, a family-run business founded near Lyon in 1996 by David Buffelard and his father, Fernand Luc Buffelard. Our battery expertise dates back to 1983 with the creation of 1000 & Une Piles, acquired by Upergy in 1999. Drawing on over 40 years of experience, Enix Power Solutions was created to meet the growing demand for customised battery solutions.
- In 2004, we expanded into the United Kingdom, establishing our Solihull facility and beginning the manufacture of our first battery packs in the UK. Our European presence subsequently grew with the opening of our Barcelona office in Spain.
- Today, Enix Power Solutions has delivered more than 3,000 custom battery projects for industrial customers worldwide. Combining engineering expertise, manufacturing capabilities and an international presence, we develop reliable battery solutions tailored to the specific requirements of each application.
