What is a Prismatic Cell Pack Machine?
A Prismatic Cell Pack Machine refers to the automated or semiautomated equipment used to assemble prismatic lithiumion battery cells into modules and then integrate those modules into complete battery packs. These machines are the core components of a battery pack production line, especially for applications in electric vehicles (EVs), energy storage systems (ESS), and industrial equipment like forklifts, AGVs (autonomous guided vehicles), and mining machines.
Unlike cylindrical or pouch cells, prismatic cells are rigid, rectangularshaped batteries usually housed in aluminum or steel casings, which makes them easier to stack and integrate into structured modules and packs.
What Does a Prismatic Cell Pack Machine Do?
A Prismatic Cell Pack Machine performs a range of precision tasks that ensure the safe, efficient, and highquality assembly of battery packs. These include:
1. Cell Handling and Loading
Automatically picks and places prismatic cells from trays or racks into module frames.
Uses robotic arms or gantry systems with vacuum grippers or mechanical clamps.
Ensures accurate orientation and positioning of each cell.
2. Cell Stacking
Arranges cells into predefined configurations (e.g., 1x4, 2x6, etc.).
May involve mechanical alignment and clamping to maintain structural integrity.
Some machines include insulation layer placement between cells for thermal and electrical safety.
3. Busbar Welding
Connects cells electrically using copper or aluminum busbars.
Uses laser welding or ultrasonic welding systems for highquality, lowresistance connections.
Equipped with vision systems to ensure weld accuracy and quality control.
4. Module Housing Installation
Installs protective housing or trays around the stacked cells.
May include automated dispensing of adhesives or thermal interface materials (TIM).
Fastening systems (e.g., screws, clips) are applied using robotic or pneumatic tools.
5. Cooling System Integration
For liquidcooled systems, integrates cooling plates or heat exchangers.
Includes sealing and leak testing of cooling channels.
6. Electrical and Functional Testing
Tests each module for:
Voltage consistency
Internal resistance
Communication with the Battery Management System (BMS)
Some machines include burnin testing or partial charge/discharge cycles.
7. Battery Pack Integration
Assembles multiple modules into a battery pack enclosure.
Integrates the BMS, wiring harnesses, connectors, and safety systems.
May involve packlevel thermal management integration.
8. Final Testing and Quality Assurance
Performs comprehensive functional tests on the complete pack:
Full charge/discharge cycles
Communication checks
Safety interlock verification
Ensures compliance with industry standards such as UN38.3, IEC 62660, and ISO 26262.
9. Labeling and Packaging
Applies serial numbers, barcodes, or QR codes for traceability.
Packages the finished battery pack for safe transport and delivery.
Types of Prismatic Cell Pack Machines
Depending on the level of automation and production goals, these machines come in various forms:
1. Manual Machines
Used for prototyping, smallscale production, or R&D.
Require significant human involvement in loading, assembly, and testing.
Low investment, but lower consistency and throughput.
2. SemiAutomatic Machines
Combine automated functions (e.g., welding, testing) with manual handling.
Offer a balance between flexibility and efficiency.
Ideal for midscale production or custom applications.
3. Fully Automatic Machines
Highspeed, robotdriven systems with minimal human intervention.
Include AI vision systems, realtime data tracking, and MES integration.
Used in largescale EV or ESS manufacturing facilities.
High initial cost but excellent repeatability, traceability, and throughput.
