OCPP 1.6J compatible

← Nabíječky

With OCPP the connection will be established from charger (client) to evcc (server). The charger needs to be able to reach evcc via the host name (functioning DNS resolution required!) or via the IP address on port 8887. By default, the first incoming connection with any station identifier is used. In order to be able to clearly assign several charging points, the respective station identifier (stationid: ) and connector number (connector: ) must be configured. Many wallboxes automatically add the station id to the backend URL, some have to do this manually ws://<evcc-host>:8887/<stationid>. If the charger supports sending metering values, try to adjust the interval to a short time span (< 10s) . Use your RFID tags (this allows e.g. vehicle identification) or set your charger to "free charging" or "autostart" to generate the transaction required for charging release.

If the charger does not offer any option to start transactions locally, the remotestart advanced option can be used to automatically start a transaction as soon as a vehicle is connected. This should only be necessary in exceptional cases.

Requirements:

If necessary, remove previously configured OCPP profiles (e.g. used for a different backend connection) in the charger configuration
Backend URL (Central System) in the charger configuration: ws://<evcc-host>:8887/ (possibly add stationid)
Protocol: OCPP-J v1.6, ocpp16j, JSON, Websocket, ws:// or similar
No encryption, no authentication, no password
Local network connection

The specific configuration and the actual usable functionality depend on the charger model and its software.

Parametry

Název	Popis	Úroveň
`stationid`	Station ID Unique identifier of the charger. Automatically detected once the charger connects. Příklad: `EVB-P12354`	volitelné
`connector`	Connector number For multi-connector stations. Numbering starts at 1. Výchozí: `1`	pokročilé
`chargingprofile`	Charging profile type Use TxProfile only if the charger ignores TxDefaultProfile changes during an active transaction. Without a transaction, TxDefaultProfile is still used; an active transaction must report its ID. TxProfile expires with its transaction. The default profile is restored on the next control cycle. If evcc is offline then, the charger may charge without this limit until it reconnects. Výchozí: `TxDefaultProfile`	pokročilé
`remotestart`	Start remote transaction on vehicle connection Only enable this option if there is no way to initiate transactions from the charger side! This is only the case if e.g. no RFID reader is available and charging processes would have to be released individually via app. Normally, the charger should always be configured at the device so that either an RFID card is used for activation or the charger is set to "Autostart", "Free Charging" or similar. First check the documentation and configuration possibilities of the charger, ask the manufacturer if necessary! (Uses OCPP RemoteStartTransaction)	pokročilé
`idtag`	Authentication token This option is only required in exceptional cases if the charger requires a specific token for accepting external transactions. (Uses OCPP RemoteStartTransaction) Příklad: `evcc`	pokročilé
`connecttimeout`	Timeout for registration Timeout for the registration of the charging point Výchozí: `5m`	pokročilé
`meterinterval`	Transmission interval for meter values Time interval for transmission of meter values (MeterValueSampleInterval) Výchozí: `10s`	pokročilé
`metervalues`	Meter values for transmission Manual specification of the meter values to be configured (MeterValuesSampledData) Příklad: `Energy.Active.Import.Register,Power.Active.Import,SoC,Current.Offered,Power.Offered,Current.Import,Voltage`	pokročilé
