Electric car drivers won’t be able to boil a kettle while rapid charging says National Grid

Experts from the National Grid have warned that if you are rapidly charging a car at home, boiling a kettle or using other electrical appliances at the same time could trip the main fuse of your home.

The UK's electricity transmission system provider has warned that using everyday electrical appliances such as kettles, toasters and microwaves at the same time as rapidly charging an electric car could cause serious problems within household's main fuses.


With the recent announcement on the 2040 ban of all petrol and diesel cars still very much a topic of discussion, the nation is turning towards electric cars. According to the Financial Times average sales of electric vehicles are up by 22 per cent since 2016.

According to the National Grid future electric cars will have a battery capacity of 90-kilowatt hours for motorists to travel on journeys of up to 300 miles.

The average charging time for an electric car with a 90kw battery is 19 hours. However, certain cars have rapid chargers, which can decrease this time to just six hours or so - but the National Grid has warned that during this time owners might not be able to use high demand appliances.

In contrast, founder of charging company Podpoint, Erik Fairbairn, told the Financial Times: "Only five per cent of homes in Britain would be able to take a more powerful charger than 7kW.

"This will be fast enough for most needs, as people will only very rarely run the electric car battery all the way down during normal daily use."

The National Grid insists that it is a major issue, however. A spokesperson for the company explained the reason that the high voltage of charging a car from the mains of a house wouldn't work.

They said: "The average household is supplied with single phase electricity and is fitted with a main fuse of 60-80 amps.

"If one were to use an above average power charger, say 11kW, this would require 48 amps. When using such a charger it would mean that you could not use other high demand electrical items without tripping the house's main fuse."
