Hello,

I have scheduled charging configured on my car. I connected my car yesterday evening to charger and the charging session was started, session time started increasing and so on. However, when the actual charging started in the morning, the charger stopped increasing Time.Session, and the energy counters also stopped registering (within OCPP, active energy import, energy session) while the charger supplied about 20kWh energy, but there is no record of it. It seems nothing in sent to car except Charging state change.

Charger is on latest firmware.

Hello,

have you configured MeterValuesSampledData to send data that you are interested in, and MeterValueSampleInterval for MeterValues reporting interval?

MeterValuesSampledData currently supports Energy.Active.Import.Register, Current.Import, Current.Offered, Temperature and Voltage.

MeterValueSampleInterval by default is 3600 seconds (1 hour).

Hello,

Yes. Normally, when charger and car immediately starts the charging, these counters increase but I cannot tell if it was an error on the ocpp central station software or the charger side, as I am only administrator of the ocpp software, I have not wrote it.

thanks

It looks like charger configuration problem. Can You check values of MeterValuesSampledData and MeterValueSampleInterval on the charger?
