Cell OCV Testing Machine
- Product description
-
- Commodity name: Cell OCV Testing Machine
The Huiyao Laser Cell OCV Testing & Sorting Machine is a critical component for ensuring the quality and consistency of prismatic battery modules. This semi-automatic station is designed to accurately measure the Open Circuit Voltage (OCV), AC Internal Resistance (ACIR), and polarity of individual cells *before* they enter the main assembly line. By sorting cells into precise groups based on these parameters, it guarantees module balancing, safety, and optimal performance.
Equipment Overview
The Huiyao Laser Cell OCV Testing & Sorting Machine is a critical component for ensuring the quality and consistency of prismatic battery modules. This semi-automatic station is designed to accurately measure the Open Circuit Voltage (OCV), AC Internal Resistance (ACIR), and polarity of individual cells *before* they enter the main assembly line. By sorting cells into precise groups based on these parameters, it guarantees module balancing, safety, and optimal performance.
Mechanical Specifications
● Compatible Cells: Prismatic 280Ah, 314Ah (and other custom specifications).
● Handling: Manual loading and unloading of cells onto the testing fixture.
● Fixture: High-precision probes and fixtures to ensure stable, low-resistance connections during testing.
● Sorting: Operator-assisted sorting based on data provided by the testing system.
Process Control System
● Core Component: Integrated high-precision battery tester (e.g., Hopetech or equivalent).
● Test Parameters:
● Open Circuit Voltage (OCV)
● AC Internal Resistance (ACIR)
● Polarity Check (Positive/Negative)
●Control Interface: PLC and HMI (Touch Screen) for setting testing parameters (e.g., OCV voltage/resistance limits).
●Workflow: 1. Operator manually places a cell into the testing fixture. 2. Operator initiates the test via the HMI. 3. The system automatically performs OCV, ACIR, and polarity tests. 4. Test results (Pass/Fail) are displayed on the HMI. 5. Operator manually sorts the cell into the appropriate "Pass" or "Fail" bin based on the displayed result.
Electrical Specifications
● Main Power Supply: AC 220V, 50/60Hz.
● Internal Tester: Requires stable power for the high-precision internal resistance tester and PLC.
● Control Voltage: DC 24V.
Safety Features
● Polarity Protection: The system automatically detects and alarms for reverse polarity to prevent short circuits.
● Operator Safety: Low-voltage testing environment with clear Pass/Fail indicators.
● Equipment Safety: Fused circuits and emergency stop (E-stop) button.
Environment & Installation
● Environment: Requires a clean, dry, and static-controlled indoor environment.
● Installation: Stand-alone station. Requires standard AC power connection.
● Grounding: Equipment must be reliably grounded.
Optional Configurations
● Data Logging: Optional upgrade to automatically log all test results (OCV, ACIR) to a PC or MES system via Ethernet/RS232.
● Automated Sorting: Can be upgraded to a fully automated sorting station with robotic arms or pneumatic pushers to sort cells into different grade bins (e.g., Grade A, Grade B).
Maintenance and Warranty
● Maintenance: Requires regular calibration of the OCV/ACIR tester probes and fixtures to ensure measurement accuracy. Keep probes clean of dust and debris.
● Warranty & Support: We provide free on-site training for operators on how to use the testing HMI, set parameters, and perform basic maintenance.
● Support: Comprehensive 2-year warranty and lifetime technical support.
