Prismatic Battery Automatic Testing and Sorting Equipment

Product Overview

This automated testing and sorting system is designed for prismatic lithium battery cells that require controlled electrical inspection, grading, pairing, and discharge handling within one production process. It combines a computer, dedicated software, precision voltage and internal-resistance measurement, inkjet marking, batch feeding, robotic grade sorting, and automatic unloading. The result is a structured workflow for turning measured cell data into repeatable sorting decisions with less manual intervention.

The equipment is suited to lithium battery cell production, pack assembly preparation, incoming-cell evaluation, and process-development operations where open-circuit voltage and AC internal resistance are critical pairing parameters. By sorting cells into as many as eight matched groups in a single operation, the system supports improved consistency among cells selected for pack manufacturing and gives production teams a practical basis for controlling cell allocation.

Built around automatic data acquisition and process control, this unit is intended for demanding routine operation. Its specified sorting accuracy of 99.9%, sorting qualification rate of at least 98%, and equipment operation rate of at least 95% provide measurable indicators for buyers evaluating process repeatability, throughput stability, and the reliability of automated cell classification.

Key Features

• Integrated Electrical Test and Sorting Process: This system brings open-circuit voltage testing, AC internal-resistance testing, grading, pairing, marking, and discharge handling into an automated sequence. Combining these operations reduces handoffs between separate test and sorting activities and keeps the classification process tied directly to collected measurement data.

• Precision Measurement Configuration: The equipment uses dedicated precision voltage and internal-resistance measurement instruments for automatic acquisition of the two specified sorting parameters. This measured-data foundation supports accurate classification decisions instead of relying on manual reading, recording, or judgment during routine production.

• Up to Eight Pairing Groups: The unit can complete sorting and pairing into a maximum of eight groups in one operation. This capability gives production personnel a defined method for separating cells by electrical performance parameters before they enter a battery pack process.

• Secondary Testing for Edge Grades: Edge-grade cells can receive secondary testing with a voltage deviation of plus or minus 0.1 mV and an internal-resistance deviation of plus or minus 0.05 mOhm. This additional control point is valuable where borderline classifications require closer confirmation before final group assignment.

• Automated Material Handling: Batch loading through a hopper, robotic automatic grade sorting, and automatic unloading are incorporated into the equipment. The material-handling arrangement supports a more consistent production rhythm while limiting the manual handling associated with individual cell testing and placement.

• Specified Production Efficiency: The system is specified for sorting efficiency of at least 10 PPM and approximately 600 tested and paired cells per hour. These figures allow manufacturing and procurement teams to assess the equipment against planned cell volume and operator-allocation requirements.

• High Sorting Performance Metrics: Specified product qualification is at least 99%, sorting qualification is at least 98%, and sorting accuracy is 99.9%. These performance measures focus evaluation on the outcomes that matter in a cell grouping process: dependable classification, repeatable pairing, and reduced risk of unsuitable cell combinations entering pack preparation.

• Database-Based Traceability: Cell performance data are managed in a database for long-term retention, historical traceability, and export. The industrial computer automatically collects data and generates curve charts and bar charts, enabling teams to retain a direct record of the measurements and sorting outcomes associated with each production run.

• Process Analysis Support: The accompanying software provides data-analysis functions for longer-term monitoring of product performance and quality. Teams can use retained test information to review trends that may inform battery formulation development and production-process improvement activities.

• Straightforward Automatic Operation: Automatic process control coordinates the test and sorting sequence after hopper loading. The operating approach is designed to simplify recurring cell grading work, replace manual participation in the core sorting flow, and preserve the accuracy of collected test parameters throughout the pairing process.

Why Choose This Product

• Controlled, Data-Led Cell Allocation: This equipment bases sorting and pairing on automatically acquired open-circuit voltage and AC internal-resistance data. That approach gives production teams a defined and repeatable basis for assigning cells to groups rather than depending on manual testing and manual sorting steps.

• Performance Metrics Buyers Can Evaluate: The stated sorting accuracy of 99.9%, product qualification rate of at least 99%, sorting qualification rate of at least 98%, and operation rate of at least 95% make the expected operating standard explicit. These metrics are directly relevant when comparing equipment for consistent pack-preparation workflows.

• Built for Routine Automated Throughput: Hopper batch loading, robotic sorting, automatic unloading, and a sorting efficiency of at least 10 PPM support recurring production work. Approximately 600 cells can be tested and paired per hour, helping operations evaluate capacity alongside the required electrical control.

• Traceability That Extends Beyond the Test Station: Database management retains performance data over the long term, while history retrieval, export, curve charts, bar charts, and analysis functions provide practical access to the information. This supports both immediate production review and longer-term quality monitoring.

• Precision Where Classification Is Most Sensitive: Secondary testing for edge grades applies the specified ±0.1mV voltage deviation and ±0.05mΩ internal-resistance deviation. This added verification capability is particularly relevant when close grade boundaries require disciplined measurement control before final pairing.
