🛠️ Charge point general configuration

The charge point configuration contains basic information about the charge point and its operative details, such as:

  • Charge Point ID,
  • Connectivity details (central system URI and OCPP protocol version, etc.)
  • OCPP information (vendor, model, firmware, etc.),
  • logging settings,
  • hardware settings

The following tables represent attributes, their values and descriptions that require more attention and might not be self-explanatory. Some attributes can have multiple possible values, if any are empty, they will be treated as disabled or might not work properly.

chargePoint connectionSettings

Attribute Description Possible values
id ID of the charging point. Must be registered in the Central System Default:"ChargePi"
protocolVersion Version of the OCPP protocol. "1.6", "2.0.1"
serverUri URI of the Central System with the port and endpoint. ""
basicAuthUser HTTP username for authentication with the Central System Any string value
basicAuthPass HTTP username for authentication with the Central System Any string value
tls TLS certificate paths

chargePoint connectionSettings tls

Attribute Description Possible values
CACertificatePath Root/CA certificate path. Any valid path
clientCertificatePath Client certificate Any valid path
clientKeyPath Client private key Any valid path
