Charger socket states
This document describes the different states on the charger's sockets and how they are shown on eMabler UI and API.
| State | Description |
|---|---|
Available | This is the standard status of a socket when there is no cable connected but it is otherwise connected to backend and working ok. |
Preparing | When cable is connected to charging station but there is no authorization done yet and the actual transaction has not started. |
Charging | When transaction is started and there is energy flowing to the vehicle then state is Charging. |
SuspendedCHARGER | If charger stops energy flow to the vehicle but cable is still connected and transaction is ongoing this is the status. Charger might go to this status if it has example load management algorithm that will adjust the charging currents. So charger decides to put the charging current below 6A and thats why it goes to this state. In OCPP this state is called SuspendedEVSE. |
SuspendedCAR | This state is activated if the charger notices that car is not taking any energy any more. Transaction is still active though, cable is connected etc. but no energy is flowing. Charger can see this on energy meter values. Why vehicle is not taking anymore energy might be because battery is full or there is a charging schedule set on the cars side that specifies charging only on certain time. |
Finishing | Charger goes to this state if charging transaction is ended example by a remote stop command from the backend. But the cable remains connected between the car and the charger. This state is active until the cable is disconnected. |
Reserved | If a reservation message is sent from the backend to the charger, then this state is activated. Usually the state is only active for 15-30 mins and then charger will release the reservation if transaction is not started before that. From this state charger will go to Charging or Available |
Booting | This is eMabler generated state when we see that the charger is booting up. |
Error | This is a state of charger where there is a malfunction on the charger side. |
Offline | This is eMabler generated state where wee see that the socket or charger has lost connection to us. |
Unavailable | This is a state that can be activated by the backend system. Usually this state is activated if there is some maintenance scheduled on the unit and operator wants to prevent anybody to start a new charging transaction on it. |
Info | This is not a state that socket or charger will be in. But there are info messages from the charger that can be send with this status. |
