The increased use of electric vehicles (EVs) presents significant challenges for domestic power supplies, according to the UK's National Grid. Bigger chargers that would significantly cut battery charging time are not suitable for most homes, and even medium-sized chargers of around 11 kW could not be used at the same time as kettles or other appliances without tripping the main household fuse. In addition, there is a risk that EVs will become too expensive in order to make them commercially viable.

Solutions could include increasing the amperage of household mains fuses, but it is likely that more on-street charging facilities will need to be provided, as many future users will not have charging facilities at home.
