Battery ERP — Material, cell, pack, and supply-chain management with real-time

commodity pricing and Fabric Lakehouse analytics.

Covers the full battery value chain: lithium, cobalt, nickel, manganese, graphite

through cell chemistries (NMC-811, NCA, LFP, LMO) to battery packs with BOM costing,

supplier scoring, inventory management, and what-if cost scenarios.

mcp-name: io.github.icohangar-ops/battery-erp

What this is

Battery ERP manages the complete battery value chain — from raw material sourcing through cell manufacturing to pack assembly. Every cost is traceable to a specific material, supplier, and price point.

Quick start

# From PyPI — https://pypi.org/project/battery-erp/
python3 -m pip install 'battery-erp[mcp]'   # MCP tools

git clone https://github.com/icohangar-ops/battery-erp.git
cd battery-erp
python3 -m pip install -e '.[dev]'
PYTHONPATH=src python3 -m pytest tests/ -v

# Domain modules
python3 -c "
from battery_erp.pricing import calculate_cell_cost_summary, get_material_price_table
prices = get_material_price_table()
for chem in ['NMC-811', 'NMC-622', 'NCA', 'LFP', 'LMO']:
    r = calculate_cell_cost_summary(chem, 50.0, prices)
    print(f'{chem}: \${r[\"cost_per_kwh\"]:.1f}/kWh (BOM: \${r[\"bom_cost_usd\"]:.2f})')

Core modules

battery_erp.core.models

All domain dataclasses:

• RawMaterial — material catalog with pricing, HS codes, hazards
• CellChemistry — NMC-111/622/811, NCA, LFP, LMO with energy density and cycle life
• BatteryCell — cell specs (capacity, voltage, form factor, weight)
• BatteryPack — pack assembly (cells + BMS + thermal)
• BOMItem — bill of materials line item with waste factor
• Supplier — supplier catalog with quality rating, lead time, certifications
• InventoryRecord — warehouse positions with reorder logic
• PurchaseOrder — PO lifecycle tracking
• ManufacturingBatch — production batch yield tracking
• PriceHistory — commodity price time series

battery_erp.core.rules

Deterministic business rules:

• rollup_bom_cost() — total BOM cost with material breakdown and waste cost
• calculate_cell_bom() — generate representative BOM for any chemistry
• calculate_pack_bom() — pack-level BOM (cells + casing + BMS + cooling)
• update_inventory_status() — recalculate in_stock/low/out_of_stock
• check_reorder_suggestions() — generate PO suggestions
• calculate_batch_metrics() — aggregate manufacturing yield
• analyze_price_history() — price trend analysis with volatility
• estimate_cell_cost_impact() — what-if cost scenario modeling
• calculate_pack_metrics() — pack energy density and efficiency

battery_erp.supply_chain

Supply chain management:

• score_supplier() — composite score (quality 35%, OTD 35%, lead time 20%, certs 10%)
• rank_suppliers() — rank by score, filter by material
• create_purchase_order() — PO creation from supplier data
• analyze_po_pipeline() — PO pipeline analysis (overdue detection, lead time tracking)
• suggest_dual_sourcing() — dual-sourcing strategy recommendation

battery_erp.pricing

Commodity pricing:

• get_material_price_table() — default prices for 20+ battery materials
• calculate_cell_cost_summary() — quick cost estimate per chemistry
• update_prices_from_alpha_vantage() — live commodity price fetch
• update_prices_from_fred() — macro economic indicators

battery_erp.analytics

Microsoft Fabric Integration

Fabric Notebooks

Delta Table Schema

Fabric Quick Start

1. Run fabric_setup_lakehouse.py to create all 11 Delta tables
2. Run fabric_cost_dashboard.py for the full analytics dashboard
3. Dashboard covers: chemistry cost comparison, pack-level costing, inventory health, supplier scorecard, price trends, manufacturing yield, cost scenarios

Inventory adapters (REST + MCP)

Battery ERP is a domain library, not a hosted ERP. For SMS / text-line and agent workflows, a shared InventoryService sits under both a thin REST API and an MCP server. Full detail: docs/INTEGRATION.md.

Do not call MCP from a browser. Keep REST and MCP in separate terminals.

Install (macOS / zsh)

Use python3. Quote pip extras so zsh does not glob them:

cd ~/Desktop/icohangar-repos/battery-erp
python3 -m pip install -e '.[dev]'   # api + mcp + pytest

Terminal A — REST (text-line backend)

cd ~/Desktop/icohangar-repos/battery-erp
export BATTERY_ERP_CONFIRM_TOKEN=dev-secret
export BATTERY_ERP_AUDIT_LOG=/tmp/battery-erp-audit.jsonl
PYTHONPATH=src python3 -m battery_erp.api

curl -s http://127.0.0.1:8088/health
curl -s http://127.0.0.1:8088/inventory/lookup/lithium

Terminal B — MCP (agents / Cursor only)

Leave Terminal A running. In a new terminal:
