UK Proposes Law To Switch Off EV Home Chargers During Peak Hours


The United Kingdom plans to pass legislation that will see EV home and workplace chargers being switched off at peak times to avoid blackouts. Announced by Transport Secretary Grant Shapps, the proposed law stipulates that electric car chargers installed at home or at the workplace may not function for up to nine hours a day to avoid overloading the national electricity grid. As of May 30, 2022, new home and workplace chargers being installed must be “smart” chargers connected to the internet and able to employ pre-sets limiting their ability to function from 8 am to 11 am and 4 pm to 10 pm. However, users of home chargers will be able to override the pre-sets should they need to, although it’s not clear how often they will be able to do that. In addition to the nine hours a day of downtime, 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 putting the electricity grid under stress at times of peak demand, potentially preventing blackouts. Public and rapid chargers on motorways and A-roads will be exempt, though.
