Charging service: E-car as storage for wind and solar power
Service also for drivers of other brands
Bidirectional charging will be important in the future
The technology is still in its infancy, and a few bureaucratic hurdles still have to be cleared. But: The first countries and manufacturers are already using bidirectional charging, and it should also be in Germany in the foreseeable future.
Electric car as part of the power grid
Temme is certain: “Bidirectional charging is a key technology. The electric car as an energy store will become an essential part of the power grid. The battery capacity is available, we just have to use it cleverly. And that will succeed if we store renewable energies when there is a lot of wind, for example, and make them available to the network during lulls.”
6200 gigawatt hours of electricity per year unused
Because: Unlike gas, coal or nuclear power plants, which largely independently supply constant electricity around the clock, wind turbines only turn when it is blowing, and solar cells only generate electricity during the day. But then often in a quantity that we cannot use all at once. Around 6,200 gigawatt hours of renewable energy are already unused in Germany every year – electricity that could power around 2.7 million electric cars for a whole year.
And: The more we rely on renewable energies, the higher the surplus that we urgently need to store; by 2030, renewable energies should increase by 230 percent, from the current 115 to 330 gigawatts of capacity.
Electric cars are ideal for storing this: They have a large battery anyway, but statistically they stand around unused for a large part of the day. If they are connected to the grid during this time, i.e. plugged into the wall box, energy suppliers can use the battery flexibly to store electricity and call it up again at peak loads.
Drivers get a bonus as a reward
Flexpole fast charging station brings flexibility
In the future, the batteries in the Flexpole could also be used batteries from VW’s ID models, which are replaced when the capacity decreases. And what works in charging stations also works at home, of course. Elke Temme: “In the future we will position ourselves even more broadly: Why shouldn’t we also offer storage solutions for your own home?”
