Don’t boil the kettle while charging your electric car because it will blow the fuse, National Grid warns

August 23, 2017

By Paul Homewood



The dead tree press have only taken five weeks to catch up on my report of this National Grid study, posted here last month!




Electric car owners have been warned that if they attempt to boil a kettle while charging their car it will blow the fuse.

The National Grid expressed concerns that an average size 3.5kW battery charger would take 19 hours to fully charge a car battery, even when it is 25 per cent full.

A “thought piece” document obtained by the Financial Times warned that a more powerful 11kW device would still take six hours to charge a car battery and during that time, the use of everyday items such as kettles and ovens would blow the fuse.

“The average household is supplied with single phase electricity and is fitted with a main fuse of 60-80 amps,” the National Grid said.

“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.”

The warnings come just weeks after the Government announced plans to ban the sale of new diesel and petrol cars by 2040 in a bid to encourage people to buy electric vehicles.

However, motoring experts immediately expressed concern, noting that it would place unprecedented strain on the National Grid.

Most electric cars will require a battery capacity of 90 kilowatt hours (kWh) to make journeys of around 300 miles, National Grid believes.

It suggests that the ability to travel longer distances without stopping to recharge will be a “must have” if motorists are to abandon petrol or diesel cars.

The company suggested that building several thousand “super fast” charging forecourts — similar to modern day petrol stations — would be preferable to a “large scale rebuild of the domestic electricity infrastructure” by fitting homes with the maximum 100 amp main fuse.

Michael Gove, the Environment Secretary, has warned that Britain “can’t carry on” with petrol and diesel cars because of the damage that they are doing to people’s health and the planet.

“There is no alternative to embracing new technology,” he said last month.

    Surely our motorways will end up with many cars on the hard shoulder with a flat battery!

      With the idea of electric only cars, I have always had fond mental pictures of the Los Angeles Freeways littered with little motionless baby carriages (prams for you).

      Oh, the swarm of “unintended consequences” which will arrive with these scientific marvels pushed by bureaucrats who likely have a string to lead them to their bathrooms.

      No, they will make it an offence to be on a motorway with inadequate charge to get to the next exit.

      There must be a future business model to mount a generator on the back of a lorry to rapidly recharge cars that have flat batteries.

        Or in your trailer, as suggested to this chap…

    Either Gove has lost his mind, or he has his arm twisted up his back.

      You cannot lose what you never had.

        Joan, you will probably be quite shocked to hear that there are some that think Gove is one of the intelligent ones. When Justice Minister – and therefore head of keeping all things legal – during a referendum interview he actually put forward a course of action to leave the EU that would break international law! He did manage to do some good as education minister since he got the leftwing teaching unions screaming against him – a sure sign you are doing good. And then because he was doing good, the liberal prime minister sacked him. As he did Owen Paterson the only other competent minister at the time, although he now has become a retarded Ultra Brexiteer.

        So what you’re saying is, there are Ultra Brexiteer’s who aren’t retarded.

    What about taking a water saving electric shower (up to 10.5kW)? ‘O, what a tangled web we weave when first we practise to deceive!’ Walter Scott, one of my Grandfather’s favourites.

    Europe is a left-wing statist construct which is bound to fail, erects tariff walls against third world primary products and lags the world in economic performance,
    Re electric cars – no need to worry, it will never happen. People will vote out politicians who take away their £1700 school run jalopy in order to have to buy a £23,000 Leaf.
