3 pin habits — leave plug in car but not in wall?

[MyNameIsMax]

Couldn’t find anything in search for this, but it’s a funny one to phrase.

I’ve been plugging in the connector end to my Model 3 when I get home, then not plugging in the 3 pin end to the wall inside until I go to bed (drama with plug sockets, don’t ask...)

Then sometimes in the morning will disconnect again from the wall, but leave it in the Model 3.

Are there any issues with leaving it connected, or disconnecting it on the wall socket end (after charging has stopped, naturally)?

I have a similar question: is it safe to disconnect the charger from the wall first then removed it from the unlocked car? Or is it essential to stop charging and disconnect the lead from the car before from the wall?

I regularly leave a type 2 cable attached to the car at work, waiting for someone else with a longer cable to finish charging. Shouldn't be a problem. What is not so safe is disconnecting whilst the charge is in progress and drawing a high current - the type-2 cable locks in place to prevent this. You have no clear guarantee that the car won't start to charge or condition unless you unlock the charge port. With 10A, I think you should be OK using the switch on the socket, but I'm not sure what the 'on load' disconnect cycle rating of a normal socket is.

It will be fine as long as you DO NOT SWITCH OFF THE POWER BEFORE STOPPING THE CHARGE, use the app to stop charging before flipping the switch

Curious to know why so? Isn't that what happens in a power cut?

Maybe so but that is a rare occurrence, continually doing that could cause spikes etc, would you want to take that chance?

I know nought about Leccy, but I thought the "data" pins were shorter and therefore disconnected first and cut the power in an orderly fashion?

Other than Commando with no interlock (bad idea anyway with risk of kids sticking things in etc.) are there installations which are not locked during charging and actually allow pulling a Type-2 cable?

The OP is leaving the plug in the charge port and just switching on/off in the house, the length of pins is irrelevant as the plug isn't being removed

I believe, when charging cold, to prevent the Tesla charge port pin freezing, the charge port pin is left unlocked to allow the charge plug even if frozen up. If I stumble across the reference, I'll post it.

It is good practice to not switch off power at the wall plug when car is charging. Done many times, this will arc and damage the wall switch. Better to stop charging, using app first.

Thanks everyone, this is really helpful. I always go into the app to stop charging, then turn off at the wall socket and then unplug the wall plug. Then to start again, plug in at the wall, turn on the socket, and the car gets itself going.
