The downfall to OVO’s drive anytime tarriff is you need a “smart” capable charger to access the tariff. If youve had an EV for a couple of years or more the chances are your charger isn’t “smart”. (Any home charger fitted after June 2022 had to be smart)
However I do like the idea of OVO’s tariff, as you are not limited to a 4hr window to charge your car,meaning you have essentially 24hrs, especially overnight when demand is low.
