Departure time charging

[brkaus]

What happens if the EVSE cannot provide the amount of power it is expecting? Then it comes up short when you need to leave.

Primary example is shared WC connector. It will give different amount of current if only one car is plugged in, or two cars are plugged in and only one is charging, or even less if both are charging.

Sure, it would work in most cases. Except when it doesn't.

Departure time based charge scheduling isn't something I'd recommend using if your charging setup isn't rock solid.

Plus, I have ideas to help make the risk of something like that a little less.

The app is pretty smart. It measures the power and determines how long it will take. It usually starts a little earlier, then stops charging for 10 or 20 min, then starts again to finish on time. If the app doesn't know about two cars charging, then of course it can't account for it. But you can manually adjust the charge rate in the app if you know it's less than normal.
