Maintain data once — deliver to every customer.
Cell, BMS, electrolyte, separator, housing and raw-material suppliers get asked the same questions every shift — every time in a different Excel template. Batteriepasswerk turns the spreadsheet ping-pong into a controlled self-service.
Six topics clogging the supplier business today.
Excel from an EV maker, PDF form from a BESS customer, online form from a storage OEM. Per customer the same answer is asked for in a different shape.
Due-diligence requires origin and risk analysis down to tier 2/3. Manufacturers often delegate that one-to-one to you.
You want to disclose regulatory fields without giving away your commercial margin in datasheets. Visibility must be controllable per customer.
Datasheet rev. 3 was shipped two months ago — is it still current? Was rev. 4 released to all customers? Version control is mandatory.
Which data version was shared, when, with which customer? Whoever can answer has the calmer audit day.
If you sell components under your own brand, you need not just data — you need your own passports including QR.
Indirect — but unmistakable.
Data for due diligence
If your customer falls under Annex X, you need solid origin and risk documentation for lithium, nickel, cobalt and graphite.
from 18.08.2027Material and component fields
Chemistry, share by mass, safety information, LCA — structured per DIN DKE SPEC 99100 so your data fits every passport.
from 18.02.2027Data availability as supply feature
Extended manufacturer obligations increasingly land as data-delivery obligations in your supply contracts — response times and completeness become contract KPIs.
already standardYour material data lands in every customer passport — maintained in one place.
Cell, BMS, electrolyte, separator, housing and raw-material suppliers are asked for the same data every day, every time in a different Excel template. Batteriepasswerk structures your master dataset once and exposes it to your customers via a controlled self-service link.
Three building blocks built for suppliers.
Self-service link per customer
Every customer gets their own link with their own visibility level. What you don't want to share stays hidden. What you share is always current.
Upload certificates once, reuse the data points
Upload conformity, REACH and LCA reports once. Relevant values are extracted via OCR/AI into the data model and made available to every customer link instantly.
Audit trail across versions and customers
Which version was released, when, to which customer? Three clicks. Audit mode for authorities built in.
For suppliers: Starter or Pro.
Anyone serving 1–3 material positions and fewer than 5 customers starts in Starter. With more customers, more positions and a dedicated audit trail, move to Pro.
What suppliers ask most.
One answer, many customers — set up your first self-service link for free.
Create the master data, configure visibility, share your first material. No contract, no setup fee — face the next request with calm.
