Charge Limit can block charging forever #224

Closed borg42 closed 1 year ago

borg42 commented 1 year ago

If a car connects to a WARP Charger and is blocked from charging (by EVCC for example) and then disconnects again without ever charging, the clear_on_disconnect of slot 12 (the charge limit slot) can trigger.

If the sequence of events is right it is now possible that the charge limit module runs in a loop where the internal "was_charging" flag is set to false, while the current of slot 12 is set to 0.

In this case the charge limit module will block forever (since it waits for a charging session to start, which is not possible anymore at this point). This deadlock can only be resolved by restarting the ESP.

Error is no longer reproducible. Thanks for your quick response
