@Steelmen Have you spoke to BP and requested a new generation charger, which has a stronger signal strength or indeed spoken to |Motability teling them the charger is useless so charging you car off peak via scheduales is equally useless due to the outdated 2g sim. There is reports on speak ev of getting the the latest generation chagers for those that report it.
In the meantime can you schedule charging from their web page or from your car.
