Where it all began

2008 our founders faced a way too common problem. An expensive Li-ion battery pack they had built was dead, due to a Battery Management System (BMS) malfunction. Instead of following others and developing ever more complex BMS, this lead them to invent a power electronics technology that does not require BMS to guard the battery.

L7 core technology is still based on that same idea, only much refined and expanded. With L7 Drive system, you can always rely on your battery pack to be in perfect balance and last as long as the cell manufacturer´s specification

What we do

Today, our core technology is employed on multiple different platforms. We have developed new services around it to complement the functions and helping you to manage your own solutions the best way possible.

Our power electronics technology can be utilised in multiple ways from Electric Mobility to Telecom sector power back-up and VPP systems. The cloud-based services guarantee that you are always up to date and in control of your solution, whatever it is.

We can also help you to find the best solution to your challenges, whenever they have something to do with batteries, motor drives, power backup, VPP or IoT services.

Our unique mix of power electronics knowledge, innovative Li-Ion battery pack technology and competence in Internet of Energy makes the difference.
