Identification
| Field | Value |
|---|---|
| Test case name | Clock-aligned Meter Values |
| Test case Id | TC_071_CS |
| System under test | Charge Point |
Description
The Charge Point is able to send different kinds of Clock-aligned MeterValues with a certain interval. What MeterValues are to be sent and at what time(intervals) is configurable.
Purpose
Check whether the Charge Point is able to send MeterValues as configured.
Prerequisite(s)
- N/a
Before (Preparations)
Configuration State(s):
- MeterValueSampleInterval is 0.
- ClockAlignedDataInterval is <Configured Clock Aligned Data interval>.
Memory State(s):
- N/a
Reusable State(s):
- GetConfiguration for key MeterValuesAlignedData
- Charging
Scenario Detail(s)
| Charge Point (SUT) | Central System (Tool) |
|---|---|
| [Will be sent every x seconds as configured in the Configuration Key ClockAlignedDataInterval).]; 1. The Charge Point sends a MeterValues.req to the Central System. | 2. The Central System responds with a MeterValues.conf to the Charge Point. |
| [The OCTT waits three times the configured ClockAlignedDataInterval (in seconds) after starting the transaction.] | n/a |
Tool validation(s)
Charge Point side:
Step 1:
(Message: MeterValues.req)
- Between the MeterValue.timestamp fields of the sent MeterValues.req should be an interval of x seconds as configured with Configuration Key TClockAlignedDataInterval.
- The MeterValue.timestamp should contain a Clock- aligned value. (For example in case of a 20s interval, the seconds should be of value; 0, 20, 40)
- The sampledValue.context should be Sample.Clock
- The sampledValue list should contain an sampledValue for each sampledValue.measurand configured in the MeterValuesAlignedData Configuration Key (the measurands returned in step 2).
- When the value for MeterValuesAlignedData is empty the measurand Energy.Active.Import.Register is assumed as default.
- None of the provided sampledValues shall have location = EV, except when measurand = SoC.
- The sampledValue.format should be Raw or omitted.
