Are you prepared for the Government’s plans to ban the sale of new petrol & diesel vehicles from 2040? You might not be able to charge your electric vehicles without blowing a fuse in your home.
According to the National Grid, it’s very likely that owners of electric cars in many homes aren’t able to charge their vehicles at the same time as boiling a kettle. This warning comes as the UK prepares for a future where cars run solely on electricity as oppose to petrol or diesel in an attempt to battle climate change by reducing air pollution.
A typical 3.5 kW charger would take 19 hours to charge an electric car to its full capacity, that’s no good. People would probably prefer a more powerful 11 kW charger, which can recharge an average electric car in six hours.
But here’s the problem, according to National Grid:
“The average household is supplied with single phase electricity and is fitted with a main fuse of 60-80 amps (of electric charge). If you were to use an above average power charger, such as 11kW, this would require 48 amps. When using such a charger it would mean that you could not use other high demand electrical items (such as kettles, oven, and immersion heaters) without tripping the house’s main fuse.”
However, there are possible solutions to this challenge. One is that it’s possible to retrofit houses with main fuses that carry 100 amps or more, but this is complex and expensive process.
Therefore, the National Rail states that it would be better to build a system of shared, “super-fast” charging points all over the country.
