Car buyers are considering whether they should switch to e-mobility or give preference to a diesel or gasoline engine. And then the Federal Ministry of Economics goes public with the message that electricity for the charging stations may have to be rationed in order to avoid widespread blackouts.
Volkswagen reports a tripling of sales of electrified cars in 2020 compared to the previous year. This is undoubtedly a success that many e-skeptics would not have thought possible. The power with which VW marketing has achieved these numbers can also become a problem in the long run.
Just as the automobile's greatest problem has become its success, so could the battery-powered car. It is already clear that a hundred percent conversion of the global combustion engine fleet into battery cars cannot be achieved without energy miracles. Because the EU is preparing for the fact that charging current will soon have to be rationed.
What is so harmlessly called peak smoothing is the tough shutdown of charging stations when the e-mobile owners do what is expected of them: namely, charging the battery overnight if possible. »The reserves in the low-voltage networks are not as high as is often assumed. We have the problem that we cannot provide every service at all times. Our networks work up a sweat when several electric cars in a residential area are charging with 11 or even 22 kW, ”says the Austrian electricity manager Reinhard Nenning. In Germany, public charging stations are not affected, according to the Ministry of Economic Affairs. The federal government wants to oblige gas station operators to provide charging stations in the future.
At the beginning of 2018 it was said on a website of the energy supplier: “Not only do we have more than enough electricity for electric cars today. No, the energy suppliers could easily guarantee the power supply even with a theoretical share of 100 percent of electric cars, ”it sounds completely different two years later.
The power grids have been adapted to the growing demand, but the reserves are too small for a rapidly growing demand for electricity from electric mobility. A blackout would have dramatic effects on the entire industrial infrastructure. To put it bluntly, the electricity for charging stations could be switched off so that automakers can continue to produce electric cars. An almost satirical vicious circle.
Professor Harald Lesch sees black for the power supply
You can see a critical video on electric mobility by Professor Harald Lesch here:
How complex and largely opaque the conditions on the electricity market are can be seen from the official statistics of the Federal Network Agency. It is reported that in 2020 electricity imports increased by 36 percent compared to the previous year because the electricity generated domestically was no longer sufficient.
The operators of the large transmission grids assume that Germany will be more dependent on electricity imports in the future in order to be able to maintain the electricity supply in extreme situations.
Renewable energies are not enough to power millions of electric vehicles
With the switch to wind and solar power, the safe performance in the power system, regardless of weather conditions, is reduced. While the federal government believes that electric mobility is the key to combating climate change, electric vehicles continue to charge a lot of electricity from coal and nuclear energy. It wasn't really intended that way.
It looks like a trend is already emerging on the market and in customer decisions that can compensate for a lack of electricity: the plug-in hybrid. See the Volkswagen graphic, which also shows the success of the plug-in hybrid.
