The 3 that will not work are all newly installed, all branded as BP ChargeMaster with the large BP logo on the front, as shown in the attached image.
I have used Chargemaster ultra chargers before, with no problems, but the ones that work are just Chargemaster Ultracharge, which have been installed for around 6 months or longer, not branded as BP. This may be completely unrelated, but it’s what the chargers have in common.
Has anyone else had this problem with the new chargers? Or is it just me? Is there something stopping the car and charger communicating?
I have a 2015 Nissan Leaf by the way.
