Battery Manufacturing EquipmentHangke storage-cell high-temperature series negative-pressure formation machine
Hangke's storage-cell formation machine runs precharge and negative-pressure formation for prismatic storage cells at high temperature, with the cells charged in series. It combines power, mechanical, vacuum, safety and measurement and control modules. Hangke lists efficiency as CC≤85% and DC≤82% and claims better cell consistency and faster commissioning.
Series charging and the efficiency figures
The machine combines high-temperature operation, negative pressure and series charging, and Hangke says this improves cell consistency and commissioning speed. It gives no string length, per-cell voltage control, balancing method or temperature range. Ask for the circuit layout and what happens when one cell hits its voltage or temperature limit before the others, since cells sharing one current path can still behave differently.
The efficiency field reads CC≤85%, DC≤82%. Ask Hangke what CC and DC stand for and why the figures are written as upper limits, and get the definitions in writing. If you compare this machine with a water-cooled capacity-grading machine, use the same operating conditions and energy-metering points for both.

Temperature and negative pressure in the real recipe
Send the storage-cell capacity, construction, fill-port details and the formation and rest sequence. Ask for the heating layout, allowed temperature spread and measuring points at the offered loading. The product name says high temperature but gives no range. For negative pressure, ask for the pressure reference, measuring point and leak and containment procedure that apply to this model.
In a series layout, define how contacts, wiring and vacuum hoses are checked and how a faulty position is isolated. Ask whether pulling one cell stops the whole string, how the remaining cells are held and how the recipe resumes. Include fixture cleaning and exhaust handling in the utility and maintenance scope, since cells can release gas or electrolyte during formation.
Energy metering, cell records and fault handling
If energy efficiency matters to your purchase, agree where energy is metered, which charge/discharge conditions apply and whether pumps, heating, cooling and standby are counted. Get the manufacturer's explanation of the published CC/DC figures first. Build any payback estimate on your own metered acceptance run.
Record the voltage and temperature of each cell through a representative string, along with total current and pressure. Set allowed recipe deviations, reject handling and the link to later grading and inspection. Hangke names safety and measurement modules without a protection list. At handover, get the response to lost contact, overvoltage, abnormal temperature and power failure, with traceable recovery for part-processed cells.
Series formation trades individual channel control for lower conversion losses, so compare it with the Repower series formation system on cell isolation and fault handling.

Questions that change the purchase
| Decision | What the catalogue says | Next step |
|---|---|---|
| How are cells controlled in the series circuit? | The page gives no string length, balancing or per-cell limits. | Review the circuit layout and watch a limiting-cell and fault sequence. |
| What do the efficiency figures mean? | The page lists CC≤85% andDC≤82% without defining CC or DC. | Get a written explanation and agree the energy-metering points. |
| Can thermal/vacuum conditions be qualified together? | The page gives no temperature or pressure range or measuring method. | Run the offered fixture with loaded cells and traceable sensors. |
