Never had a problem in the nearly 4 years I’ve been charging, but then, I am on Octopus Go & have a Viridian SimplEV charger (was a pre-production unit I got for £300, now sold on their site – but not for the UK), so I just use the car’s inbuilt schedule to charge from 0:30 to 5:30am. I can plug in at any time, it only charges on the schedule.
Phaedra and others affected by the new lack of access to the API on their VW group cars can do the same, so you could plug in and just forget about it, let the car take the strain instead of the Octopus/charger app.
In life, it's not who you know that's important, it's how your wife found out.
