Charging quality is decisive - for usability, service life and cost-effectiveness.

IEI is a leading high-tech company for onboard chargers - precisely tuned systems that we develop, test and implement.


Our charging solutions exist where space, temperatures, dirt, vibrations, continuous use and load cycles place extreme demands. Where every charging interruption is expensive and where individual solutions should not cost too much.

IEI develops solutions that fit precisely into a wide variety of scenarios - robust, safe, practical.

Charging process

Charging quality is decided during the process - and is crucial. The charging process is more than just power consumption: it influences the performance, service life and safety of the battery.

Whether fast or gentle: anyone who electrifies systems must understand charging cycles - and provide intelligent answers to the respective challenges. This is precisely our strength at IEI.
