Back on topic…
I bought (leased) a new Megane EV in November last year.
Chargemap - essentially my view is as others have said. I have it, and the app is useful especially for the information about the locality, but actually I haven’t used it to pay for a charge. Basically because their tariffs are higher than others.
Mobilize (Renault’s in house offering) same as Chargemap as far as I can see, except the map included in the My Renault app is less reliable and less complete. Tariffs seem identical to Chargemap.
Octopus Electroverse - my preferred option up to now. The map is fairly reliable and up to date, and typically their tariff is around 4c per KwH lower than the others - a worthwhile saving. HOWEVER - despite ordering the card in November, it still hasn’t arrived so I have to use the app to charge. All fine until I have no mobile network or it decides to play up. Their much vaunted customer service seem unable to do anything to help, so on occasion I have had to use Mobilize instead at extra cost.
Lidl - certainly where I’ve charge up, paying by debit card wasn’t available at the borne. Have to set up yet another account with bank details etc on the Lidl + app. Don’t mind, but it doesn’t save me anything compared to Electroverse so haven’t bothered.
I’ve also used IE Charge, less well known but a smaller French owned company who only put charge points in rural areas. Very good tariffs, currently 25c per KwH on offer but normally 30c, lower than Lidl. But stations few and far between at present, my nearest is16km away but if en route they are great value with up to 320KW charge available.
The local departmental providers have many bornes in surrounding villages. We’re in the 37, but only 5 miles from the 36 and the 86, all 3 departments have different providers, but only a max charge rate of 22kW and quite expensive - 48c in our village, 44c in the 86 and a nonsensical minimum fee of 10 Euros in the 36. Unsurprisingly they’re all usually available…wonder why?
Not yet done a really long journey (eg a UK visit) but all 3 cards/apps will function anywhere I’m likely to go. Just a question of the price really.
