## Short answer

AI ERP for EV battery manufacturers puts a private language model over the ERP and the systems around it so quality, planning and compliance teams can ask questions about lot genealogy, cell grading, supplier material and scrap in plain English. It runs on the customer's own infrastructure, which matters because electrode recipes, yield curves and customer pack designs are among the most sensitive data a battery maker holds.

## Intro

A battery plant is a process-manufacturing plant at the front and a discrete assembly plant at the back. Slurry mixing, coating, calendering and slitting run as continuous or batch processes with material yield and recipe control. Winding or stacking, electrolyte fill, formation and aging, and then grading turn that material into cells, which are assembled into modules and packs. Most ERPs were built for one of those worlds, and battery makers live in both.

The ERP usually owns the bill of materials, purchasing, inventory, costing, sales orders and finance. The MES, the formation and test equipment software and the quality system own the process data. The hard questions sit between them: which cathode lot went into which cells, which of those cells ended up in a pack that shipped to a given customer, and what did that lot do to formation yield. Answering that today often means an engineer and three exports.

Regulation is raising the stakes. The EU Battery Regulation (2023/1542) brings carbon footprint declarations, recycled content documentation and a digital battery passport for industrial and EV batteries. Customers apply IATF 16949 expectations, UN 38.3 transport testing and UL or IEC safety standards, and many US buyers ask for sourcing documentation tied to content rules. Each of these is a data assembly job across systems.

This page describes how private AI on top of the ERP can help battery makers with those jobs, what it should not be trusted to do, and how to deploy it so recipes, yields and customer designs never reach a public model API.

## Pain Points

### Genealogy is split across systems

**Detail:** Material lots live in the ERP, process parameters in the MES, and formation and grading results in tester databases. A recall or customer complaint needs one chain from raw material lot to pack serial, and building it is a manual project each time.

### Yield loss hides in early process steps

**Detail:** A coating weight drift or a slurry viscosity excursion shows up weeks later as capacity fade or self-discharge at grading. By then the ERP has already costed the scrap as a single variance with little cause attached.

### Formation and aging capacity is a bottleneck nobody can see

**Detail:** Formation channels and aging rooms are fixed-capacity assets with long dwell times. Planning them from the ERP's generic work center capacity gives schedules that look feasible and are not.

### Regulatory data is assembled by hand

**Detail:** Battery passport fields, recycled content shares, carbon footprint inputs and supplier due diligence records are pulled from purchasing, bills of material and supplier portals by a compliance analyst for each product family.

### Supplier material variability is poorly tracked

**Detail:** Cathode and anode active material, separators and electrolyte vary lot to lot. Incoming inspection results rarely get linked to downstream cell performance in a way planners and supplier quality engineers can query.

## Use Cases

### Cell-to-material genealogy queries

**Description:** A quality engineer asks which cells contain a named cathode lot, and which packs and customers received those cells, and gets a traceable answer from joined ERP, MES and test data.

**Erp Objects:** Lot and serial master, goods receipt, production order components, shipment lines, MES cell records

**Outcome:** Turns a multi-day containment investigation into a query that scopes the affected population in minutes, subject to how complete the source data is.

### Formation and grading yield explainer

**Description:** The assistant compares yield by cell lot, line, coating batch and supplier lot, and highlights the factor that separates good and bad groups for an engineer to confirm.

**Erp Objects:** Production order confirmations, scrap postings, batch characteristics, grading results

**Outcome:** Moves early-process root cause work from spreadsheet joins to a reviewed shortlist of likely drivers.

### Supplier incoming-quality summarizer

**Description:** Reads certificates of analysis, incoming inspection records and NCRs per supplier lot and drafts a supplier scorecard narrative for the supplier quality team.

**Erp Objects:** Purchase order receipts, inspection lots, vendor master, quality notifications

**Outcome:** Cuts the manual prep before supplier reviews and surfaces repeat issues sooner.

### Battery passport data assembly

**Description:** Collects declared fields from bills of material, material masters and supplier declarations into a draft record per product, flagging missing or inconsistent entries.

**Erp Objects:** BOM, material master, vendor declarations, product family master

**Outcome:** Shifts compliance staff from collecting data to reviewing gaps, with the final declaration still owned by a person.

### Pack build shortage triage

**Description:** Planners ask why a pack order cannot start and get the shortage chain: cells held in aging, modules awaiting a BMS board, or an open supplier delay.

**Erp Objects:** Planned and production orders, MRP exceptions, inventory by status, purchase order schedule lines

**Outcome:** Shortens the daily shortage meeting by arriving with causes instead of lists.

### Engineering change impact on cell and pack BOMs

**Description:** For a proposed change to a separator or tab material, lists open orders, stock, supplier lots and customer approvals affected, and drafts the change notice for review.

**Erp Objects:** ECO records, multi-level BOM, open production orders, inventory, customer approval documents

**Outcome:** Gives change boards a fuller impact view before the decision, not after.

### Dangerous goods shipping document checks

**Description:** Checks outbound shipment records for lithium battery classification, state of charge declarations and test summary references before documents are released.

**Erp Objects:** Delivery documents, material master transport data, test report attachments

**Outcome:** Catches missing or inconsistent shipping data early; the dangerous goods signatory still approves.

## Architecture

**Overview:** The AI layer joins data the ERP already holds with read access to the MES, quality and test systems, then answers questions with the queries it ran visible to the user. Models are open-weight and run on the plant's own GPUs.

**Layers:**

#### Connectors

**Detail:** Read-only ERP access through APIs or reporting views, plus MES and tester database connections, each using a scoped service account that respects existing roles.

#### Genealogy semantic layer

**Detail:** A mapping of lot, batch, cell, module and pack identifiers across systems so a question about a material lot resolves to the right downstream serials.

#### Model serving

**Detail:** Open-weight models served with vLLM or Ollama on customer hardware or a sovereign cloud, sized for engineering query volume rather than consumer scale.

#### Retrieval and agents

**Detail:** Retrieval over certificates, specifications, NCRs and work instructions, with agents that draft records and notices but never post transactions without approval.

#### Governance and audit

**Detail:** Every question, generated query and answer is logged with the user identity, and recipe or design data can be excluded from retrieval by role.

## Deployment Options

### Air-gapped on-prem

**Fit:** Cell makers whose electrode recipes and process windows are core intellectual property.

**Detail:** Model, retrieval index and connectors run inside the plant network with no outbound path, and updates are brought in through a controlled process.

### Private or sovereign cloud

**Fit:** Pack integrators and newer plants without a large data center footprint.

**Detail:** A dedicated tenant under the customer's own cloud agreement, with regional residency matching the plant's customers and regulators.

### Hybrid by site

**Fit:** Groups with a pilot line in one country and volume plants in others.

**Detail:** Per-site retrieval and models keep process data local, while a governance layer standardizes questions and reporting across sites.

## Compliance

### The system assembles declared data and supplier evidence into drafts and flags gaps; the manufacturer remains responsible for the declaration and passport content.

**Framework:** EU Battery Regulation 2023/1542

### Traceability and containment queries support the documented process; control plans and PFMEA remain controlled documents in the quality system.

**Framework:** IATF 16949 and customer-specific requirements

### Test report references are linked to product records so shipment and certification checks can be queried; testing itself stays with accredited labs.

**Framework:** UN 38.3, UL 1973, UL 2580, IEC 62660

### On-prem deployment lets the customer keep controlled technical data and customer pack designs off third-party AI services.

**Framework:** Export control and customer NDAs

### Bill of materials and supplier origin records are queried to support the customer's own due diligence files.

**Framework:** Sourcing and content rules (US and EU)

## Integration Notes

- Lot and serial relationships are read from the ERP's batch or lot tables, then joined to MES cell identifiers using a maintained mapping rather than free-text matching.
- Tester and formation databases are accessed through read replicas or exports so production test systems are not loaded by analytical questions.
- Certificates of analysis and inspection PDFs are indexed with their lot number as metadata, so retrieval filters on lot before the model reads anything.
- Supplier declarations for passport fields are stored as structured records where possible, with the source document linked for audit.
- ECO and BOM reads use the ERP's effectivity dates, so impact queries reflect what is active, not just the latest revision.
- Write-back is limited to drafts such as change notices and supplier corrective action requests that a named approver releases.

## Product Fit

### ERPray

**Why:** Planners, quality engineers and compliance staff can ask grounded questions over ERP data with the query shown, role-aware and read-only by default.

### DataRay

**Why:** Genealogy and yield questions need tester databases, file shares and certificates alongside the ERP, which is the mixed-source case DataRay is built for.

### Custom build

**Why:** Passport assembly agents and plant-specific genealogy mappings usually need a bespoke build around the plant's own identifiers.

## Buyer Questions

- Which systems does the assistant read, and how does it join lot, cell and pack identifiers across them?
- Can electrode recipes and process windows be excluded from retrieval by role?
- Where does the model run, and does any prompt or document leave our network?
- How are wrong answers detected, and can we see the exact query behind each answer?
- What does the system draft versus post, and who approves each write-back?
- How will it handle our passport and customer data fields as the regulation's delegated acts are finalized?
- What GPU capacity do we need for our user count, and what does it cost to operate?

## Faq

### Can AI replace the MES for battery traceability?

**Answer:** No. The MES records process data at the machine and step level, and that record is the evidence. AI sits on top, joining ERP and MES data so people can query it. If the underlying genealogy is incomplete, the AI will say so rather than fill gaps, and fixing capture at the source is a separate project.

### Does it help with the EU battery passport?

**Answer:** It helps assemble and check data. It can pull declared fields from bills of material, material masters and supplier documents into a draft and flag what is missing. The manufacturer still owns and signs the declaration, and the required fields depend on battery category and the final delegated acts.

### Is our electrode recipe safe?

**Answer:** Recipe data is only exposed if you connect it. With on-prem deployment the model and index sit inside your network, and role-based filters can keep recipe tables out of retrieval entirely. You should still classify that data and test the exclusions before go-live.

### Which ERPs does this work with?

**Answer:** It is ERP-agnostic. Battery makers run SAP, Oracle, Infor, Microsoft Dynamics and others, and the connectors read lot, batch, BOM and order data from whichever system is in place. Check the specific ERP pages on this site for connector details.

### Will it predict cell yield?

**Answer:** It explains yield differences between groups using data you already have and highlights candidate drivers. A true predictive model, trained on process data, is a different build and needs enough history. We would scope that separately after the explainer proves the data is usable.

### How long does a pilot take?

**Answer:** A genealogy and yield pilot on one line typically takes 6 to 10 weeks, depending on how clean the identifier mapping is across ERP, MES and tester data. The mapping work is usually the longest part, not the AI itself.

### Can we use the ERP vendor's AI instead?

**Answer:** For ERP-only questions, vendor AI may be enough, and you should evaluate it. It generally cannot join tester databases, certificates and MES data on your premises, which is where battery questions get hard. Many plants use both for different jobs.
