Project Overview
The electric vehicle revolution is creating unprecedented demand for battery manufacturing capacity. When an EV battery manufacturer secured contracts to supply modules to automakers, they needed to build production capability from the ground up—and fast.
AMD Machines was selected to design and build a complete battery module assembly line, laid out in modular zones so that capacity can be added as demand grows.
Safety-First Design
Battery manufacturing presents unique safety challenges. High-voltage components, flammable electrolytes, and the risk of thermal runaway require careful engineering at every step.
Electrical Safety
- Automatic grounding verification before any operation
- Hi-pot testing at multiple stages for insulation defects
- Emergency disconnect systems throughout the line
Thermal Monitoring
- Infrared cameras monitor cell temperatures in real-time
- Automatic rejection of any cells showing thermal anomalies
- Fire suppression systems at critical stations
- Thermal runaway containment in testing areas
Mechanical Safety
- Light curtains and area scanners at operator interfaces
- Safe speed monitoring for collaborative operations
- Emergency stop coverage throughout
Process Flow
The line performs complete module assembly from incoming cells to packaged product:
Zone 1 - Cell Preparation
- Incoming cell testing and sorting
- Polarity and voltage verification
- Vision-guided cell stacking
Zone 2 - Module Assembly
- Cell-to-busbar laser welding
- Weld quality verification
- Thermal interface material dispensing
Zone 3 - Electrical Integration
- BMS installation and connection
- Harness routing and termination
- Insulation resistance testing
Zone 4 - Final Test & Pack
- Full electrical characterization
- Capacity and impedance testing
- Labeling and packaging
Scaling for Growth
The modular zone layout is designed for capacity expansion:
- Additional cell preparation stations can be added inline
- Parallel test stations accommodate longer test cycles
- Buffer systems smooth flow between zones
- MES integration enables real-time capacity management
01The Challenge
An EV battery manufacturer needed to rapidly scale production to meet OEM commitments. The line required handling high-voltage components safely while maintaining the precision and speed necessary for automotive production volumes.
- Production volume commitments to OEMs, with capacity growth expected
- High-voltage safety requirements
- Thermal runaway prevention critical for safety
- Electrical testing and traceability required on every module
- Continuous operation
02Our Solution
AMD Machines designed a comprehensive battery module assembly line integrating cell handling, module assembly, welding, testing, and packaging—all with built-in safety systems for high-voltage operations.
Automated Cell Handling
Vision-guided robots sort, orient, and stack cylindrical cells with polarity verification and voltage testing at each step.
Precision Laser Welding
Fiber laser welding system creates the interconnects between cells with real-time weld quality monitoring and thermal imaging.
Integrated Test Systems
Each module undergoes insulation resistance testing, hi-pot testing, and capacity verification before proceeding downstream.
Thermal Management Integration
Automated dispensing of thermal interface material between cells and cooling plates.
03The Results
The line runs cell preparation, module assembly, electrical integration, and final test as one continuous flow. Electrical testing is staged through the line: incoming cell voltage and polarity checks, weld verification after laser welding, insulation resistance testing after electrical integration, and full characterization at final test. The modular zone layout leaves room to add cell preparation and test stations as volume grows.
