Battery Manufacturing EquipmentYFH-RBOCV Pouch Cell OCV Inspection System
The YFH-RBOCV measures the open-circuit voltage of pouch lithium cells. Flexible contacts handle several products, a servo contact mechanism uses CCD compensation, and the measuring instrument is configured to the customer's needs. Loading includes buffering, and each result is tied to its cell and uploaded to the customer's server.

Contacts, instrument and handling on the YFH-RBOCV
The station checks the open-circuit voltage of pouch lithium cells. Flexible contacts suit several products, and a servo-driven contact mechanism uses CCD compensation for position. Yingfenghong says the measuring instrument can be configured to the customer's needs. So the contact mechanism and the instrument are two separate parts: positioning gets the probe onto the tab, while the instrument decides voltage accuracy, settling time and calibration uncertainty.
Loading and unloading include storage or buffering, and Yingfenghong describes one operator looking after several machines. The page gives no cycle time, buffer size or throughput. Settle tray presentation, cell sizes and operator duties before you use that staffing remark in any rate calculation.
Results are tied to each product and uploaded to the customer's server. The page gives no server protocol or sample record. In a demonstration, follow a known cell through measurement and upload, including a failed reading and a dropped connection, to see the data link work on your installation.
| Parameter | Published value | Record status |
|---|---|---|
| Recorded data | Product-linked results uploaded to customer server | known |
| Measurement interface | Flexible contact with servo and CCD compensation | known |
| Test modes | Pouch cell open-circuit-voltage inspection | known |
Catalogue values apply to the configuration and test method the maker states. Ask for the values that apply to your configuration.

Two acceptance checks in one quotation
For the contact check, send the tab geometry and the allowed presentation variation across your pouch-cell family. Ask which fixtures, motion settings and changeover parts are included. For the electrical check, state the OCV range, resolution, uncertainty, timing after the previous process step and the calibration certificates you need. Keep them as two requirements even though one station does both jobs.
Place the station in your real process: incoming trays or automation, measurement, a buffer for good cells and a route for rejects. Ask whether a cell can leave the station before the receiving system has acknowledged its ID and test record. Settle this at commissioning.

Reading the catalogue entry
Yingfenghong's pages describe the product and the functions above. The price fields show zero, which is a placeholder; ask for a real quotation. The pages also make general claims about reliability and customer satisfaction, which you can test through references and a trial.
Ask Yingfenghong for its business licence and company documents with the quote. Measurement accuracy, the range of cell sizes, throughput and the data interface are all questions to put to the supplier in writing.

Follow one known pouch cell through measurement and remeasurement
Prepare typical cell sizes, tab positions and tray layouts, including the awkward combinations within your range. Ask for contact settling, measuring time and handling time to be reported one by one, since a quick positioning move is only part of a full OCV cycle.
In an agreed trial, compare the station's saved voltage with a suitable reference method on the same cells under the same conditions. Then look at a repeat measurement and a rejected contact. The record should keep the cell ID, the instrument set-up and the reason for the final decision. Decide how the station flags missing data before you connect it to a release system.

Questions that change the purchase
| Decision | What the catalogue says | Next step |
|---|---|---|
| Will the contact reach the tab reliably? | The page describes flexible contacts and servo positioning with CCD compensation. | Send tab drawings and watch repeatable contact without damage to the cell. |
| Can the readings support sorting? | The page says the instrument is configured per customer and gives no accuracy figure. | Request voltage uncertainty, settling time and an export of repeated readings. |
Equipment questions
Is this a battery pack cycler?
No. It inspects pouch-cell OCV. Charge and discharge pack cycling would need other equipment; Yingfenghong's programmable power supplies are a separate product.
Source s2 Source s3Does CCD compensation set the measurement accuracy?
No. It handles contact positioning. Ask for the voltage instrument and its calibration as a separate item; the page gives no OCV accuracy figure.
