I’ve recently been having issues with my home installed L2 charger, it either will not start charging, or will start, then stop with an error that says something similar to “Charging Operation Interrupted”. I verified that it’s the charger by using my portable L1 charger, which has no issues charging (other than being much slower, of course).
My first thought is that the connection has become dirty with time, and I need to clean it. But I’m having trouble finding something that would allow me to do so.
Is there a special cleaning tool that I can purchase to attempt to clean the charging head? Otherwise, I’ll need to purchase a new charging cord, as in my area hiring an electrician would essentially cost more just to get a diagnosis of what’s wrong (and then if the diagnosis was that the cord is dead, I’d have to buy a new one anyways).
Any extra ideas are appreciated, I bought this ChargePoint charger back in 2017.
Can you test your charger on another vehicle? It’s highly possible that your L2 charger has failed.
Also, can you reduce your L2 output amps down to something low, like 16A? If it fails at 16A, then I would argue that the charger has bigger problems than dirty contact points.
I don’t have another car to test it on, unfortunately. I’m not sure how to reduce the amperage on it, maybe through the Chargepoint App, but it doesn’t even start trying to charge, so I wonder if it’s the contacts.
I’m not aware of any special tool for it. You might try posting at r/evcharging.
With the power off, just as an extra precaution, something like an extra small q-tip with alcohol seems like a reasonable thing to try.
Is it a cph25? Chargepoint does sell replacement cables, and they are pretty easy to replace yourself. Or you can sometimes find them on eBay. Or I think I might have an extra one myself, actually.
