SAP S/4HANA Cloud Public Edition and the battery passport: integration pattern
How data from SAP S/4HANA Cloud Public Edition (SAP) reaches the battery passport through the BatteryPass API: interfaces, workflows and when we checked them.
An integration pattern, not a ready-made connector: your ERP or integration platform reads and writes through the BatteryPass API with an organisation key. The details below come from the vendor documentation and were checked on the date given.

Each integration gets a communication arrangement of its own with exactly the APIs it needs. The middleware usually runs in SAP Integration Suite or another iPaaS.

Matching workflows
Units from production
Serial numbers from the production confirmation or goods receipt are staged as an import; members review, commit and approve before any passport appears.
Passport links back into the ERP
The middleware follows the change feed and writes the GS1 Digital Link and the passport status to the serial number record in the ERP, so labels and delivery papers carry it.
Condition data from BMS and service
A battery management system or a service tool reports measurements such as capacity fade or cycles; BatteryPass accepts newer measurements and publishes according to the organisation's policy.
Returns and repairs as lifecycle events
Completed repairs, inspections and component replacements from service or return orders appear as events in the unit's history.
Product change leads to a new model version
A change to the product master in the ERP triggers a notification; a member creates a new model version in BatteryPass. Declared data is never written automatically.
Import presets
- SAP serial number list: A list of serial numbers from SAP S/4HANA as a middleware assembles it from the serial number API or the goods receipt from production. Assumes that the battery model's model identifier in BatteryPass is the SAP material number. The posting date of the goods receipt stands in for the manufacturing date; the plant stays unmapped (choose the facility in the import options).
- Generic CSV file: For any ERP and for files a middleware writes itself: GTIN, serial number, manufacturing date, facility (name or GLN), model version and battery status, with German and English column names.
