Energy Measurements
Energy Measurements / MeterValues
OCPP MeterValues are sent based on every 1 kWh of energy consumed or every 15 minutes, whichever comes sooner. With this in mind, the quickest you will receive an updated MeterValue when charging on single-phase (7 kW) is 7 minutes and 3 minutes on three-phase (22 kW) with the longest being 15 minutes since the last reading.
Charge Rate | MeterValue Frequency |
---|---|
7.4 kW (single phase) | 7 minutes |
22 kW (three phase) | 3 minutes |
Less than 1kWh consumed | 15 minutes |
Although we support the MeterValueSampleInterval key, changing this will not increase the frequency that MeterValues are received past what is outlined above. However, if you set this to every 15 minutes or above it will always be received in those time intervals regardless of whether 1 kWh or more has been consumed.
