The weight of the cable seems a bit excessive for the mechanical size of the plug and the plastic. Maybe they need to water cool the 50kW cables just to save weight? I've had protocol problems with my SparkEV, my Bolt, and our eGolf. Maybe the connector vendors are just sucking at the specifications? But yeah, CCS seems to go down a lot compared to ChadeMo. Maybe it's because it's getting used more nowadays. I'm confident they'll figure it out, I just don't want to have to drive around with a special stick in the trunk to hold the charging cable up.
The “hold up the cable” issue with the Bolt is a mechanical issue with the motorized clamp at the top of the car inlet trying to grip onto the top of the cable plug. If the plug sags down at an angle then the lock mechanism isn’t able to grab ahold of the plug. The car notices this and reports an error back to the charger.
There is no need to support the cable after the car’s clamp successfully locks on. You only need to hold up the cable for a few seconds at the very beginning of the charge initiation after the payment has been authenticated.
I have heard some Spark owners report charging problems at some (but not all) new Electrify America chargers but I don’t know what the exact underlying issue is.
What problems have you experienced with the eGolf and what model year was the car?
As for CHAdeMO, we don’t have a liquid-cooled CHAdeMO plug yet so who knows what issues it could have.
