For the last couple of years since I've had my 2020 Taycan 4S I've not been able to charge on Gridserve fast chargers. I've tried quite a few models from 50Kw to 350Kw and no matter which model I try I always get the same error message on the screen: Error. Isolation Fault. Unsafe situation was prevented. Please reconnect.

I've charged all over the UK and Europe on so many networks, Ionity, Shell, BP, Kempower, Applegreen, Tesla etc and never had an issue. What's the deal with Gridserve? Has anyone else ever had this?

I guess it could be an issue with the car but seems odd as it's happy to charge literally anywhere else. I must have tried 10 plus Gridserves in many different locations and always get the same fault.

I would ask Gridserve and Porsche for their help to resolve, sounds quite niche.

That's a new one on me. I've used Gridserve with multiple cars and never had a problem like that.

You could try asking on the SpeakEV forum, but I would definitely push this at Porsche and Gridserve.

Thanks. Yeah I had phoned Gridserve and they were stumped. I don't want to go near a Porsche dealer as I don't want the dreaded software update that borks my useable battery. It's not a major issue for me, just a bit frustrating.

I did once get Gridserve to reboot a 50kw charger and it worked after the reboot but that's the only success I've had with them.

Is there an echo ;-) I'm not that fussed, I'm sure I'll live with it, just wanted to see if I'm the only one which so far it appears I am.

Good to see your posting issue is as consistent as my Gridserve charging issue.

Mmm…I know the repeating post is a well known glitch, but is that a record? biggrin

It's incredibly unlikely to be a Gridserve issue.

Which charger manufacturer is it when you have the issue? Think the screen in the pic is an ABB?

Does it work if you use the same model of charger but on a different network?

I have a 2020 Taycan and have never had this issue at Gridserve. I think it is almost certainly an issue with the car. Maybe Gridserve chargers are just sensitive to it?

The software update doesn't reduce your range. I've had the update and if anything I think my range has gone up very slightly. My (admittedly limited) understanding is that it only restricts the range/charging if it detects a battery issue. In which case you definitely want to know about it and get it fixed.

Thank you, that's really useful.
