EV charge times

lyledunn

Apparently from September 2021 charge points placed on the U.K. market are required to be factory set not to charge during peak times, 8-11am and 4-10pm. Although the parameter can be altered by the user, it is a recognition that things are getting tight.

    According to the Sunday Times, this was (and may still be) draft legislation: https://www.driving.co.uk/news/environment/ev-chargers-switch-off-peak-times-blackouts/

    It seems to make good sense, but if the energy companies want to encourage off-peak use, then favourable tariffs are probably the best approach.

    Indeed, if preferential tariffs are to be offered then I would favour a simple to understand charge controller with three colour coded push buttons.

    RED button to charge as quickly as possible, but be aware that this carries a cost penalty.

    ORANGE button to fully charge within the next 12 hours.

    GREEN button to charge to at least 70% with the next 12 hours.

    NOTE that if no button is pressed, the vehicle will eventually charge FOR FREE but this might some several days. Select this option for lightly used vehicles.

    A similar system could be applied to washing machines for example

    RED, washes straight away, but this costs more.

    ORANGE, Cheaper and will be completed within 12 hours.

    GREEN, Cheapest and will be completed with 30 hours.
