Hi everyone! I drive a 2023 Bolt EV. I charge on campus where the rate for chargepoint is $0.50/hr from 4pm to 6am, and $1/hr from 6am to 4pm. $0.50 difference is negligible, but it’s a 100% difference from $0.50 to $1 and I’m a frugal student. What I’ll usually do is set an alarm for 5:58am so that I can press “stop charge” on the chargepoint app so I don’t have to pay the $1 rate after 6am. I’m curious if anyone has figured out a way to automate this (maybe through shortcuts?) process. For example, get the iphone to make a shortcut such that when it’s 5:59am, stop charge in the chargepoint app. I futzed around with shortcuts but didn’t find anything, thanks!
you need a relay to physically disconnect the CP and CC pins of the J1772 connector, otherwise the chargepoint kiosk will still count you as being there, obviously to make sure you actually moved your car
The cheapest way of accomplishing this is to buy a J1772 extension cable and splice into the CC and CP signals, and have an Arduino control the relay via a timer. I think the other way is to buy both a Tesla to J1772 adapter and another J1772 to Tesla adapter and splice into that
