Battery Manufacturing EquipmentHangke small-cylindrical 400-channel charge/discharge equipment
Hangke's small-cylindrical charge and discharge system is built for 21700 cells and has 400 channels. It combines power, mechanical and fire-protection sections, handles cells by tray and runs charge and discharge instructions sent from MES/IMS. Hangke also lists multi-size compatibility, a small footprint and uniform temperature control. It serves formation and grading.
400 channels and what to ask about them
Hangke lists compatibility with several cell sizes, a reduced footprint, uniform temperature control and safety protection. Beyond the 21700 label it gives no supported sizes, voltage or current ranges, channel concurrency, power limits or cooling services. Ask for this system's own figures; Hangke's 46XX formation and prismatic bus machines carry different ratings.
Ask for a terminal and tray drawing for each cell size you plan to run and a signed channel and electrical configuration. Specify the CC/CV steps, rest periods, cut-offs and your longest recipe. Channel use and good cells per shift depend on that recipe, the loading method and shared power and temperature limits, as well as the 400 channels.

Catalogue values apply to the configuration and test method the maker states. Ask for the values that apply to your configuration.

Matching MES instructions to the loaded tray
Define tray ID, the cell-position map and the recipe version before a cycle starts. Ask which checks confirm cell presence, polarity and contact, and how a failed channel is isolated. Hangke's summary describes none of these, so list the checks you need in the order.
Run a representative recipe with calibrated electrical references and compare chosen channels under the agreed load. Include a safe part-filled tray or missing-result case agreed with the manufacturer. Note whether the cycle stops, skips the affected position or asks the operator to correct it, and check that the final result keeps the right cell and tray ID.
Temperature control, fire protection and restart
Ask for the temperature-control method, sensor positions and alarm limits, with the water, air and electrical services needed. Hangke gives no uniformity figure or test load for its uniform temperature control. Fire protection is named as a subsystem without a detection method, extinguishing agent or certificate scope, so request the design and the site duties in the technical offer.
Agree what is kept after an interrupted cycle and whether MES/IMS or the equipment owns the restart. At handover, cover contact maintenance, calibration intervals, tray changeover, electrical isolation and a written response to an abnormal cell. Confirm safe operation for each small cylindrical chemistry you will run, and base acceptance on the system delivered.
Channel counts like this are typical of formation and grading lines, which the formation and capacity grading page describes.

Questions that change the purchase
| Decision | What the catalogue says | Next step |
|---|---|---|
| What runs concurrently at the required current? | The catalogue lists 400 channels with no power or concurrency limit. | Specify electrical ratings and test your planned recipe and load. |
| Which tray and cell formats are qualified? | The catalogue mentions multi-size compatibility without a size table. | Approve terminal and tray drawings and contact checks. |
| How is an interrupted recipe resumed? | The catalogue names MES/IMS communication without a recovery rule. | Document stored state, result identity and restart ownership. |
