BMW Wallbox (Delta Electronics) — Full Capability Report

Results from a full OCPP 2.0.1 GetBaseReport(FullInventory) dump performed on 2026-04-11.

Charge Point ID: DE*BMW*EXXXXXXXXXXXXXXXXX Firmware: 01.20.06.71 Connection: WiFi, OCPP 2.0.1 over WSS, Security Profile 2

Measurands Available

The wallbox only supports 4 measurands via SampledDataCtrlr:

Measurand Supported
Current.Import Yes
Energy.Active.Import.Register Yes
Power.Active.Import Yes
Voltage Yes
SoC No
Frequency No
Temperature No
Power.Factor No
Power.Active.Export No
Power.Reactive.* No
Energy.Active.Export.* No
Energy.Reactive.* No
Current.Export No
Current.Offered No

All other measurands defined in OCPP 2.0.1 MeasurandEnumType are not available on this hardware.

ISO 15118 Support

Minimal. The ISO15118Ctrlr component exists but only exposes one variable:

Variable Status Value
CentralContractValidationAllowed Accepted false
PnCEnabled UnknownVariable —
V2GCertificateInstallationEnabled UnknownVariable —
ContractValidationOffline UnknownVariable —
ContractCertificateInstallationEnabled UnknownVariable —
RequestMeteringReceipt UnknownVariable —
ISO15118EvseId UnknownVariable —
CountryName UnknownVariable —
OrganizationName UnknownVariable —
MaxScheduleTuples UnknownVariable —

Conclusion: No Plug & Charge, no ISO 15118 vehicle communication. The wallbox cannot receive vehicle data (brand, model, battery capacity, SoC) from the car. AC charging uses basic IEC 61851 pilot signal only.

Why Public Chargers Show Battery %

Public chargers that display SoC typically use:

  1. DC (CCS/CHAdeMO) — mandatory PLC communication where the car sends battery data
  2. Backend/app — the user's account has the car registered (brand, model, license plate)
  3. ISO 15118 Plug & Charge — certificate exchange identifies the contract, not the car itself

This BMW Wallbox (AC, no PnC) has no mechanism to receive car data via the cable. For vehicle info (SoC, model, battery), use the BMW Connected Drive integration or similar cloud APIs.

What Cannot Be Done

  • Get vehicle SoC — not in measurands, no ISO 15118 communication
  • Get vehicle brand/model/battery — no mechanism in OCPP or ISO 15118 on this hardware
  • Get frequency, temperature, power factor — not supported by the meter
  • Phase switching — ACPhaseSwitchingSupported = false (single phase only)
  • Trigger BootNotification/StatusNotification — wallbox rejects these triggers
