I’m on the Scottish Power Green EV. I did warn Motability that if it keeps happening, then I will hand back the car and get something more suitable to my needs. If they don’t sort it quickly, it’s going to cost me a fortune using public chargers.
So approx 5hrs overnigt rather than an intelligent tariff from Octopus or OVO, who have recently stopped supporting Ohme chargers.
Hypothetically, all you would need to do is swop out the Ohme charger with a decent reliable cheap charger c. £200-£350, that allows you to acess a base 2 rate tariffs like the one you are currently on with SP. The other way is to fit an interlocked CEE socket (commando) in place of the Ohme unit. This would be by far the cheapest option and would be basically what Tesla users often however, if your main grid earthing is PME/TN-C-S.., there would be a little bit more work involved and if you wanted app controll, thats easy done with a contactor. I’m not advising you to do any of this, it’s merely to point out options, so pointless going to deep.
What, I amd advicising you to do is, to fire an email across to CEO Andrew Miller explaining the problem that keeps reoccuring on the charger still in warranty and the cost of charging at public chargers isn’t financially viable for you, explain you have been in contact with Motability customer services and tried to explain the fault, yet all they could advice was for me to go out and buy another charger to replace the Ohme charger, thats still under warranty. Be factual, be nice how it is worded and I bet you, will hear back by email/phone within a few hours telling you, they have started the ball rolling and an engineer visit booked, far quicker than, if you had done your self. The good thing about doing it this way, you will allways have a point of contact, should it happen again!
