Open Charge Metering Format (OCMF)

Signed Snapshots shows how to create and work with snapshots. For each of them, the BSM-WS36A provides an additional representation in the Open Charge Metering Format (OCMF).

The OCMF representation is generated from the actual snapshot data when reading from the appropriate model. It contains a subset of the snapshot's information, presents the same time information and response counter and gets signed individually.

Snapshots and Their Associated OCMF Representation

Each line in the following table shows a snapshot with its associated OCMF representation:

Snapshot Snapshot Model OCMF Representation OCMF Model
Signed Current Snapshot bsm_snapshot OCMF Signed Current Snapshot bsm_ocmf
Signed Turn-On Snapshot bsm_snapshot OCMF Signed Turn-On Snapshot bsm_ocmf
Signed Turn-Off Snapshot bsm_snapshot OCMF Signed Turn-Off Snapshot bsm_ocmf
Signed Start Snapshot bsm_snapshot OCMF Signed Start Snapshot bsm_ocmf
Signed End Snapshot bsm_snapshot OCMF Signed End Snapshot bsm_ocmf

Model Instances shows these model instances.

Getting the OCMF Representation

Create the snapshot as shown in Snapshot Creation and just read its associated OCMF model instance afterwards.

Snapshot Data in OCMF

The OCMF representation includes Meta1 as customer identification data which needs to be set appropriately. The other metadata fields Meta2 and Meta2 are provided as X2 and X3, if set.

The BSM-WS36A uses the reference cumulative register (OBIS ID 1-0:1.8.0*198, data point RCR) as RV for the energy consumption in OCMF output. This register gets reset when creating a Signed Turn-On State and shows the actual energy consumption at the time of crating Signed Turn-Off Snapshot. The positive active energy (OBIS ID 1-0:1.8.0*255, data point TotWhImp) is included for informational purpose as XV.

Create Snapshot and Get OCMF Representation

  • Trigger creating Signed Current Snapshot (not its OCMF representation)

    $ bsmtool create-snapshot scs

    --> 2a 10 9e4c 0001 02 0002 bca5
<-- 2a 10 9e4c 0001 e9ed

  • Poll snapshot status as shown in Snapshot Creation

  • When ready, read its OCMF representation from OCMF Signed Current Snapshot

The current draft of the Open Charge Metering Format Specification explains the standard keys used here. Reading value is the reference cumulative register RCR:

  • RV: its actual value RCR
  • RI: RCR's OBIS ID
  • RU: RCR's unit

In addition, four vendor-specific keys are used in the reading data:

  • XV: the additional total watt hours imported counter TotWhImp
  • XI: TotWhImp's OBIS ID
  • XU: TotWhImp's unit
  • XT: the underlying snapshot's type Typ

The metadata is provided in the following fields:

  • ID: the data from Meta1
  • X2: the data from Meta2
  • X3: the data from Meta3

OCMF XML

In the context of electric vehicle charging, OCMF data gets usually validated by a so-called Transparenzsoftware. There are several implementations at the market and among them the S.A.F.E. e.V. Transparenzsoftware which uses an XML envelope.

The XML envelope includes the OCMF data taken before starting and after terminating the charging process along with the public key used for signing. The format could be generated from a template where the actual data gets inserted.

Generating OCMF XML

The BSM Python support and the BSM Tool support the generation of OCMF XML data for the OCMF representation of a pair of already created snapshots (the switching snapshots OCMF Signed Turn-On Snapshot and OCMF Signed Turn-Off Snapshot or the non-switching OCMF Signed Start Snapshot and OCMF Signed End Snapshot). To generate an OCMF XML envelope for the switching snapshots, invoke the BSM Tool as follows:
