COENG 13-Channel Cylindrical Battery Cell Sorting Machine for Voltage and Internal Resistance Testing

The COENG cylindrical battery cell sorting machine screens and sorts lithium-ion cells by voltage and internal resistance before battery PACK assembly. Featuring 13 sorting channels, configurable sorting thresholds, and a rated throughput of up to 3,500 cells per hour, it supports cell grouping within cylindrical battery pack production workflows.

Voltage and Internal Resistance Screening Before PACK Assembly

Cell selection is an important step in lithium-ion battery pack production. Grouping cells within defined voltage and internal resistance ranges helps manufacturers manage these two aspects of cell consistency before assembly.

The COENG battery voltage and internal resistance tester measures these parameters and routes cells to designated sorting channels according to preset thresholds. It provides a dedicated screening stage for manufacturers organizing cylindrical cells for subsequent battery pack assembly.

Voltage and internal resistance sorting does not replace charge-discharge capacity testing. Where capacity matching is required, a separate cell capacity testing process should be included.

13 Sorting Channels with Configurable Thresholds

The 13-channel battery sorter allows operators to set voltage and internal resistance sorting criteria for different cell groups.

Automated routing directs tested cells to their assigned collection channels, where operators collect the sorted cells for the next production stage. This arrangement supports organized cell handling during battery PACK preparation.

Key features include:

• 13 sorting channels for cell grouping.
• Configurable voltage and internal resistance thresholds.
• Automated routing to designated collection channels.
• Manual collection of sorted cells.

Throughput of Up to 3,500 Cells per Hour

With a rated sorting efficiency of up to 3,500 cells per hour, this cylindrical cell sorting equipment supports production workflows requiring repeated voltage and internal resistance screening.

Silo-type loading and cylinder-based material distribution automate portions of the cell handling process. Actual throughput depends on operating conditions, loading continuity, sorting settings, and collection arrangements.

PLC Control and Modular Electrical Design

The equipment combines PLC control with stepper motor actuators to coordinate cell handling and sorting operations. Its modular electrical control design supports maintenance access and servicing.

For battery production equipment buyers, this configuration provides a practical basis for discussing operating procedures, maintenance requirements, and integration into an existing production layout.

Technical Specifications

Cell Compatibility and Production Applications

The supplied product description specifies 18650 cylindrical cells. Buyers planning to process 21700 cells should confirm the available machine configuration, tooling requirements, and changeover procedure with COENG before ordering.

This equipment can serve as a voltage and internal resistance screening station within:

• Cylindrical lithium-ion battery PACK assembly workflows.
• Battery cell inspection and sorting operations.
• Cell preparation processes before module or pack assembly.
• Battery manufacturing equipment upgrades requiring a dedicated sorting stage.

For production planning, confirm the required cell format, sorting thresholds, throughput, and handling arrangements against the proposed equipment configuration.

Frequently Asked Questions

What does this battery cell sorting machine test?

It tests cell voltage and internal resistance, then sorts cells according to configured thresholds.

Does it measure battery capacity?

The specified functions are voltage and internal resistance testing. Charge-discharge capacity testing is not included in the supplied specifications.

Does “13 channels” mean 13 cells are tested simultaneously?

It refers to the sorting channels. The supplied specifications do not establish simultaneous testing of 13 cells. Confirm the channel allocation, including any reject channel, before ordering.

Can it process both 18650 and 21700 cells?

The description specifies 18650 cells, while the product title also references 21700. Ask COENG to confirm compatibility, required tooling, and changeover arrangements for your cell format.

What utilities are required?

The listed electrical supply is 220V, 50Hz, with equipment power of 1.5kW. Because the machine uses cylinder-based material distribution, confirm compressed-air pressure and consumption requirements before installation.

What should buyers confirm about measurement performance?

Request the voltage and internal resistance measurement ranges, accuracy, resolution, repeatability, and test instrument model. These details are necessary to assess suitability for your cell screening criteria.
