- Die Number of e-cars is increasing
- In Great Britain will first restrictions introduced – what’s behind it?
- how does it look inside Deutschland and other countries?
The number of registered electric vehicles is increasing. were 2012 still tight 200,000 vehiclesso the number has now almost fiftyfold to almost eleven million in 2020. In Deutschland is it approx 517,000 purely electric vehicles will. The current government plans that by the year 2030 seven to ten million electric cars should be allowed. All of these vehicles require charging current. To do this, the necessary infrastructure must be created and the power grid must be designed for this load. Is there a risk of the power grid collapsing?, if too many vehicles are being charged at the charging stations at the same time? Or can the network handle these amounts without any problems?
Loading times restricted in the UK: what’s really behind it?
Of course, the increasing number of electric vehicles also puts a strain on the power grids. It is comparable to an apartment. The more devices that are started up at once, the more power is consumed until it reaches the point where the fuse blows. It is similar with the power grid. The more consumers are switched on, the more energy is needed.
It could also be something like that if suddenly several million vehicles to the charging stations at the same time go – the power consumption skyrockets. A private charging station has an average power of between 11 and 22 kW. That is more than is used in a normal household. Here the largest consumers are stove and oven or one electric sauna with 8 kW, but these are only in operation for a very short time, a charging station usually for several hours. If many of these stations in one section go online at the same time, this will be heavily loaded. And then what you know from the household happens: If the load limit is exceeded, the network switches off there and everything goes dark.
To avoid this, in Great Britain be ready Law enacted to prevent this. But what does this law really say? Is it that it’s for It is impossible for drivers of e-cars to charge their vehicles at home or at work at certain times? In fact, according to the government’s will, private or workplace charging stations between 8:00 a.m. and 11:00 a.m. and between 4:00 p.m. and 10:00 p.m. However, this only applies to new charging stations, which must be equipped accordingly to enable this shutdown. But there are no rules without exceptions: because it is possible to unlock it. This is intended to give drivers whose daily routine is designed in such a way that they have to use these times the opportunity to recharge.
Germany: Are we threatened with a similar scenario?
In addition to the limited loading times, so-called “randomised days” intended. This means the British government reserves the right before, on certain days the To interrupt power supply in congested areas for charging stations for 30 minutes at a time.
However, one generally goes not from a blackout out, these measures would only be a precautionary measure to prevent exactly this. So far, this has only been used to ensure that the power grid does not collapse if too many are charging their vehicles at the same time.
How is it in Germany? This was discussed before the electionswhether a similar loading ban could also be introduced here. This was not pursued further. However, it is to be expected that this topic will be discussed again in this legislative period.
Editor’s Note: In an earlier version of the article, the headline was misleading. The impression could be given that in Great Britain e-cars are generally no longer supplied with electricity and that e-mobility poses an acute threat to the power grids. It is not so. We’ve corrected the headline to avoid spreading misleading information about EVs and their impact on power grids. The British government’s measures are now also correctly presented in the headline. We apologize for the previous wording error. (signed Io Görz, Editor-in-Chief)
