Scheduled charging not working - Car stuck when offered spikeAmpsToCancel6ALimit. Offering 2 less.

Open db9carbon opened this issue 4 years ago • 3 comments

v1.2.1. EV Car is a Polestar 2.

On schedule charging, the charge does not start. Log dump (debug set to 10). In this example, schedule is 1400-1500, at 10amps.

Now, I can successfully start a charge from the new HTTP interface by pressing 'Start All charging'

It also seems, pressing 'Start Charge now' does not work either, gives same error as the schedule.

Great work on this fork by the way, as I am looking for half an hour charging scheduling from 0030-0430, so also keen to help test that when you deprecate the original web interface!

Starting/stopping charging is done through the Tesla API, which obviously doesn't do anything for a non-Tesla EV. The TWC is not capable of offering no energy if it's in communication with TWCManager. You may want to change stopping mode to "Stop Responding," which will cause the TWC to offer absolutely nothing.

Although pressing ''Start All charging' on the new interface, does start the charge, i.e. not via the Tesla API

I get lots of this Log entries when no car is plugged.

TWCSlave 20 Car stuck when offered spikeAmpsToCancel6ALimit. Offering 2 less.

To be more precise: The entries are created twice after this log: TWCManager 20 Limiting charging to XX.XXA - YY.YYA = ZZ.ZZA. and ZZ.ZZ is in between 10 .. 16 A.

I'm not sure if there is something wrong, because but the documentation says: "it's still drawing at least # 2A less than spikeAmpsToCancel6ALimit." and no car is plugged.
