I'm a late-February orderer, and had the gen 3 wall connector installed last week. Posted to the Facebook Tesla groups if there were any local car owners who might like to help me test the installation. I wanted to see if it would go to full 32A power delivery, and, you know, work, without blowing up my house or something. Someone kindly popped over this morning with their 18 month old Model 3 RWD - the car was one of the first off the Shanghai production line, apparently.
My take on the wall connector is as follows:
- Perfect for minimal effort charging - it doesn't require all the faffing around that you'd endure with the universal mobile connector (UMC)
- I think the wall connector is safer than the UMC, particularly for continued use - the plug is designed to provide a secure connection for high current delivery; on the other hand, plugging and unplugging something to a standard wall plug, like you would every couple of days with the UMC, may cause wear and tear over time
- I like that I can get a full charge in about 8 hours - although I understand the reasoning some come to that they can live with the slower 10A available from the UMC + standard wall plug
- You take the plug, press the button near the Tesla's butt hole, and the Tesla opens it up - this required no pre configuration, the guy just drove his Model 3 up and it all "just worked"
- After it's plugged in, the car locks the plug to the charging port, and the touch screen goes in to charging mode showing the battery info (see photo below)
- The car took seconds to ramp up to full 32A power delivery
- To stop charging / unplug, hold the button on the plug for a few seconds and you hear a click, the plug is unlocked and holding the button down you can pull the plug from the charging port
Although it's internet connected, you don't get any information from the wall connector itself. If you browse to the wall connector's IP address on your WIFI network, all you get is a basic screen with the wall connector's serial number.
You can go into "commissioning mode", by turning it off and on with an upstream isolation switch, or by holding the plug button down for a period of time. Commissioning mode lets you:
- Configure the WIFI
- Specify whether you want to restrict the connector to specific Tesla cars, all Tesla cars, or all cars
- Change the maximum power delivery (which your electrician should specify when they install)
- Update the wall connector's firmware
All-in-all I see the wall connector is designed just to sit there as an appliance ready to charge your car. There's talk about future firmware updates offering new features, but no one know what the features will be. Perhaps monitoring, but who knows?
My understanding is you can tell the car to schedule recharging at different times e.g. if you have peak / off peak tarriffs with your electricity company.
