About Digatron Power Electronics
Digatron Power Electronics develops and manufactures test and formation systems for batteries and electrical energy storage. The portfolio includes cyclers for individual cells, modules and HV packs, high-current discharge units, fuel cell testers as well as computer-controlled systems for formation, grading and ageing of lead-acid and lithium batteries, complemented by end-of-line testers and single-station machines for pouch cell manufacturing. The systems are used in research, development, production and quality assurance, including customers from the battery industry, e-mobility and stationary energy storage. The offering is supplemented by the Battery Manager 4 software, seminars, service and hotline. Around 250 employees work at locations in Germany, the USA, Italy and India; headquarters are in Aachen. The company has existed for more than half a century and supplies customers worldwide.
