Something certainly weird going on there and more so with the car?
Have Skoda changed API’s, causing a conflict between the charger and car?
As Ive mentioned before, I normally put a thin bead of silicone round the back of any charger installed on a substrate. This just add a little extra protection especially if there’s not 100% silicone coverage over the screw holes. However, this doesn’t guarantee or insinute an higher IP rating.
The problem with Ohme and many charger’s like it, is the PCB is open to moisture, if the case isn’t fully sealed, given the PCB is open with no additional protection covering it and your well aware of what moisture ingress can do to a PCB.
You can buy a charger cover but, it doesn’t protect from any possible ingress from behind. You can also get a magnetc weatherproof cover for the charging port when charging.
For better protection of the charger, a homemade complete cover with a silcone bead around the rear and a small cutout, just enough for the cable to pass through when the door is closed. Sponge rubber could be used to better weather protect the door when closed and around the small cable hole if neccessary. Treated wood, would be the easiest to use and have a 1o-15yr lifespan if looked after.
The Easee one charger although still only IP 54 rated, has some distinct advantages over the likes of Ohme’s E-Pod – The Type 2 Socket is at the bottom of the charger, so less chance of water getting in. There is an additional cover that encases/protects the PCB from external influencies such has moisture & water ingress!
