EV & Battery Manufacturing Automation Built Around the Cell Line, the Pack Line, and the Dry Room
We work across what's genuinely different about EV manufacturing -- battery cell, module, and pack production, thermal and safety monitoring, EV powertrain assembly, and cell-to-vehicle traceability -- bringing IoT, machine vision, and automation to the specific problems EV and battery manufacturers actually have: battery safety risk, dry-room energy intensity, high-voltage testing, and traceability that has to survive a recall or a second-life battery decision years later. This is the monitoring, data, and automation layer around EV and battery manufacturing -- not a certified battery management system (BMS) or functional-safety system, and not positioned as one.
The Weight of Complexity in EV & Battery Manufacturing
Battery cell manufacturing running in tightly controlled dry-room environments, where a contamination or moisture excursion is discovered as a yield loss rather than caught at the point it happens
Battery module and pack assembly depending on sampling and post-process testing to catch a weld, connection, or assembly defect
Thermal and safety risk in battery production and storage areas that depends on a person or a fixed sensor threshold noticing it in time, rather than continuous, camera-based early detection
EV powertrain assembly (motor, inverter, gearbox) and high-voltage system testing generating data that's captured separately from the rest of the plant
Dry-room dehumidification and battery-line energy consumption -- among the most energy-intensive parts of an EV plant -- reviewed periodically instead of managed in real time
Cell-to-module-to-pack-to-vehicle traceability maintained across disconnected systems, slowing a recall, warranty claim, or root-cause investigation years after production
Battery raw material provenance -- lithium, cobalt, nickel -- tracked manually or not at all, despite growing regulatory and ESG pressure for supply-chain traceability
Plant control systems built up across multiple automation vendors as a gigafactory or EV line scales, without a unified view
None of this is unique to any one EV or battery plant -- it's the shape of manufacturing a genuinely new class of product under real safety and traceability pressure. It's also exactly where we've spent our engineering time: the monitoring, data, and automation layer around EV manufacturing, not certified battery safety or functional-safety systems themselves.
Value Chain
Where We Work Across EV & Battery Manufacturing
EV manufacturing spans battery production, EV-specific powertrain assembly, and the vehicle assembly process it shares with general automotive. Here's where this platform applies, stage by stage:
Battery Cell Manufacturing
- Machine-vision-based foreign-particle and contamination detection on cell manufacturing lines, catching an issue before it becomes a yield loss
- Real-time dry-room environmental monitoring -- humidity, particulate -- tied directly to production data, not tracked separately
Battery Module & Pack Assembly
- Machine-vision-based weld and connection quality inspection on battery tabs, busbars, and module interconnects
- Condition-based monitoring for module and pack assembly equipment, flagging wear before it affects assembly quality
Battery Safety & Thermal Monitoring
- Continuous, camera- and sensor-based thermal monitoring of battery production and storage areas, flagging an abnormal heat signature early
- Built as a monitoring and early-detection layer that complements your certified battery management system (BMS) and functional-safety systems -- not a replacement for them
EV Powertrain Assembly
- Real-time OEE and cycle-time tracking for electric motor, inverter, and gearbox assembly lines
- End-of-line high-voltage and insulation-resistance test data captured and tied directly to the specific unit
Body Shop & Paint Operations
- The same body-in-white and paint-shop capability already covered for general vehicle assembly -- weld quality tracking, dimensional inspection, and paint defect detection -- applies directly to EV body and paint lines, since this part of the process is largely shared across vehicle types
Final Vehicle Assembly & High-Voltage Safety Testing
- Real-time OEE, cycle time, and andon-event tracking at the line and station level
- End-of-line high-voltage system and insulation testing data tied to the specific VIN, alongside the rest of vehicle quality data
Battery & Vehicle Traceability
- Cell-to-module-to-pack-to-vehicle traceability, so a battery issue can be traced back to a specific cell lot or production batch years after the vehicle is on the road
- Non-conformance and CAPA workflows tied to the specific cell, module, pack, or vehicle involved, using the same corrective/preventive action structure already proven on the EpsumThings platform
Energy & Utilities Management
- Real-time energy monitoring for dry-room dehumidification and battery-line utilities -- among the most energy-intensive systems in an EV plant -- tracked against actual output
- The same energy-monitoring approach already proven on energy-intensive process operations elsewhere in manufacturing
Plant-Wide Automation & SCADA/MES Integration
- Multi-vendor PLC, robot, and SCADA integration bringing cell, module, pack, powertrain, and assembly control systems onto a single, browser-based view
- Built for plants running multiple automation vendors as a line or gigafactory scales, without forcing a single-brand standard
Enterprise, ERP & Battery Supply Chain
- Manufacturing ERP tying production planning, inventory, and shop-floor data into one system rather than a spreadsheet-driven process
- Raw material and battery supply-chain traceability data connected into the same platform, supporting ESG and provenance reporting requirements
Machine Vision for Battery & EV Quality Inspection
Machine vision earns its place in EV and battery manufacturing because a defect caught at the cell or module stage costs far less -- in yield, safety, and reputation -- than one caught after the vehicle is in the field. The same underlying Vision AI capability already proven for conveyor, material, and weld inspection in industrial operations applies directly here:
Cell Contamination Detection
Foreign-particle and contamination detection on battery cell lines.
Weld & Connection Quality
Weld and connection-quality inspection on battery tabs, busbars, and modules.
Body & Paint Inspection
Dimensional and surface inspection on EV body and paint operations.
Configured to the specific defect types and tolerances that matter at each stage, rather than a fixed, single-purpose inspection tool.
Cell-to-Vehicle Traceability & Provenance
EV manufacturing demands a traceability chain that extends from critical raw minerals (lithium, cobalt, nickel) through cell formation, module assembly, and pack integration, down to the final vehicle VIN. Continuous quality and genealogy data capture on EpsumThings provides a queryable record that supports warranty management, safety investigations, second-life battery decisions, and ESG compliance reporting years after production.
Built on EpsumThings
Every capability on this page runs on EpsumThings, Hailiot's industrial operations platform -- Unified Data Lake for multi-vendor data integration across cell, module, pack, and assembly systems, Web-SCADA for unified visibility, SCADAA for trend and deviation analytics, Vision AI for the inspection and thermal-monitoring work described above, Workflow Automation for quality, CAPA, and traceability workflows, and AI Agents for the next layer of autonomous decision support. This is the same platform already proven across steel and power operations -- built to extend into EV and battery manufacturing, working alongside your certified battery safety and functional-safety systems rather than replacing them.

Battery weld and connection quality tracked and traced as it happens, instead of relying on sampling
Abnormal thermal signatures in battery areas flagged early, as a monitoring layer alongside certified safety systems
Cell-to-vehicle traceability captured continuously, supporting recall and warranty investigations years later
Dry-room and battery-line energy consumption tracked against actual output in real time
Frequently Asked Questions
Auto Components covers Tier 1/2/3 parts manufacturing. Automotive covers general OEM vehicle assembly -- body shop, paint, powertrain, final assembly. This page covers what's genuinely specific to EVs: battery cell, module, and pack manufacturing, battery safety and thermal monitoring, EV powertrain (motor, inverter), and cell-to-vehicle traceability. Body shop and paint operations are largely shared with general vehicle assembly -- see the Automotive page for that detail rather than repeating it here.
Have a Question, or Discovering Battery Quality or Safety Issues After the Fact?
If a cell contamination issue, a weld defect, or an early-stage thermal signature depends on sampling or manual observation rather than a system that catches it in real time, that's exactly the gap this platform is built to close.
