Dennis Schulmeyer was contemplating the huge potential of electric cars long before Tesla became a household name. The IT entrepreneur and qualified electrical engineer was already developing initial ideas back in 2009 for a comprehensive, integrated charging system using power from renewable energy sources. Since 2020, he has been developing and producing complete solutions for efficient electric vehicle charging at LADE GmbH, the company he founded in Mainz.
“I want us to do everything we can to keep the planet a livable place,” says Schulmeyer, explaining his motivation. “In e-mobility, we see an enormous lever for making the necessary changes as quickly as possible and in an economically efficient way.”
Schulmeyer believes that electric vehicles can do more than just cut CO2 emissions from road traffic. He wants to use the millions of such vehicles on the roads of the future as local storage units for renewably generated electricity. Electric cars could help to even out power fluctuations and stabilize power grids. “Vehicle-to-Grid” (V2G) is the name of the technology behind this plan, where electric vehicles would not only be charged from the grid but could also feed power back into it.
The LADE GmbH system for operating charging infrastructure comprises both hardware (including electronics) and software (the operator backend and smartphone app). The technological centerpiece is the load management system known as Zero Gap, which provides dynamic, phase-individual, real-time control of each single charging point. Schulmeyer is convinced of his vision: “With Vehicle-to-Grid, we can massively reduce CO2 emissions from both road traffic and power generation.” And he goes a step further: almost the entire power supply in Germany “can be guaranteed just from wind power, solar energy and electric cars with V2G functionality.” See for yourself.
