My Number one tip for using rapid chargers. Figure out what you need and only charge that don’t be like ICE at a fuel station filling the tank to the top.
Say on your way home and you need another 15% to top up so just top up enough to finish the journey. Yes it takes more planning but whacking it up to 80% if you don’t need to is the difference between say a £20 charge and a £60 one (figures just plucked outta my bottom).
Other tip use offers like Octopus where you can get discounted rapid charging at certain times or just discounted for using Octopus. Same as Ovo was Bonnet and others.
As has been mentioned shop about Tesla chargers can be very cheap too
Oh you can setup Plug and Charge with Electroverse now so no cards or apps just plug in and charge
Intelligent Octopus customers get an 8% discount on rapid charging too as well as doing plunge charging when the price drops at certain times sometimes by quite a lot my last charge was 20% discount plus the 8% intelligent octopus customer discount too
