AuthRequired: Signaled when an EVSE needs authorization to start a transaction
TransactionStarted: Signaled when a transaction has been started. Transaction starts at the point that all conditions for charging are met: EV is connected and user has been authorized
PrepareCharging: EVSE started to prepare for charging. DC: CableCheck, PreCharge, PowerDelivery. AC: wait for the car to proceed to state C/D

ChargingPausedEVSE: Signaled when charging is paused by the EVSE
ChargingResumed: Charging has resumed from a pause
StoppingCharging: EVSE has started to stop the charging process. DC: CurrentDemand has finished, now doing WeldingCheck etc, AC: Wait for car to return to state B or A
ChargingFinished: Charging is finished. Essentially the same as TransactionFinished, but emitted for clarity
TransactionFinished: Signaled when the transaction finished. Transaction finishes at the point where one of the preconditions for charging irrevocably becomes false: When a user swipes to stop the transaction and the stop is authorized.
SessionFinished: Session finishes at the point that the EVSE is available again (no cable plugged)
Error: Signaled when an error occured. An error doesnt prevent further charging operations.
AllErrorsCleared: Signalled when all errors are cleared
PermanentFault: Signaled when there is a permanent fault at the EVSE. A permanent fault prevents further charging operations
