UK: soon a law to limit charging times for electric cars
The UK is proposing a law requiring home battery chargers to be turned off for electric cars during peak hours.
From next year into force, this new law aims to protect the network from excessive stresses; however, it will not apply to public chargers. At the same time, however, it reveals how ecological evolution is, in reality, fragile and not supported by an efficient and sufficient distribution system.
Announced by Transportation Secretary Grant Shapps, the bill requires electric car chargers installed at home or in the workplace to be turned off for nine hours a day to avoid overloading the national electricity grid.
As of May 30, 2022, new home and work chargers installed must be "smart" chargers connected to the Internet and capable of using presets that limit their ability to operate from 8am to 11am and 4pm: 00 to 22:00. However, home charger users will be able to override the presets if necessary, although it is not clear how often they will be allowed to do so. In addition to the nine hours a day of inactivity, authorities will be able to impose a "randomized delay" of 30 minutes on individual chargers in certain areas to prevent grid spikes at other times.
The UK government believes these measures will help avoid stressing the electricity grid at times of peak demand, potentially preventing blackouts. On the other hand, public and rapid shippers on motorways and expressways will be exempted.
The concerns of the Department of Transportation are justified by the projection that 14 million electric cars will be in circulation by 2030. If everyone came home from 5 to 7 pm as is now, and loaded the cars, we would have the risk of a general overload of the network. . The government argues that the new legislation could also help electric vehicle drivers save money by prompting them to charge their electric vehicles during off-peak night hours, when many energy suppliers offer "Economy 7" electric rates that are far beyond below the 17p ($ 0.23) average cost per kWh.
In the future, Vehicle-to-Grid (V2G) technology is also expected to reduce stress on the grid in combination with V2G-compatible smart chargers. Bi-directional charging will allow electric vehicles to bridge power gaps when demand is high and then recover energy when demand is extremely low.
