2. What does this machine do? (Essential process for factory battery cells)

1. Standardized complete charging and discharging, accurately measuring the true capacity of each cell;
2. Automatically divides into A/B/C modes based on capacity, platform voltage, and internal resistance;
3. Reassembling the battery pack with cells at the same level reduces overall voltage difference and extends lifespan;
4. At the same time, it can perform single-cell cycle aging and verify cell cycle life;
5. Energy Feedback Design: The discharge of cells is returned to the power grid, saving electricity.

1. Host computer: Set processes, view curves, export sorting reports
2. Mid-level computer: stores massive cell data, with records not lost during power outages
3. ACDC: Two-way AC conversion in the power grid
4. DCDC: 96 independent charge/discharge channels, each controlled independently
5. Tested on: Single square cell (probe/alligator clip directly clamping cell tabs)

3. Core Parameter Plain Translation (Beginner Focus)

1. Voltage range (only single cell tested)

• Charging 0~5V, minimum discharge cutoff at 1.5V;
• Lithium iron standard range 2.5~3.65V, ternary 2.75~4.2V, fully covered.

2. Current capacity (suitable for large capacity large cells)

• Low current: small-capacity cells, slow charging and standing;
• 60A full range: 280Ah/300Ah large driver 1C rate charge/discharge to simulate real-world usage rates. Maximum single-channel power is 300W.

3. Accuracy (Sorting core, must be accurate)

4. Basic hardware parameters

• The full load power of the entire machine is 28.8KW, powered by three-phase five-wire 380V industrial power (not suitable for household use);
• Dimensions 2000×1050×1850mm, weight <850KG, large vertical cabinet;
• Forced air cooling, IP20 indoor use, noise <75dB;
• Four-wire sampling: eliminates wire voltage drop, making capacity measurement more accurate.

4. Core Software Functions (Essential for Battery Cell Factories)

1. Fully automatic volumetric sorting (highlight): After charging and discharging, automatic data is collected: capacity, constant current platform voltage, median discharge voltage, internal resistance. Custom rules automatically classify, one-click export of Excel sorting table, directly distinguishing qualified and defective cells.
2. Rich step editing includes constant current charging, constant voltage charging, constant current and constant voltage (standard lithium battery process), constant power, standing, and unlimited cycles, with up to 254 steps per cycle. Supports 3-layer nested cycles to simulate long-cycle aging of cells.
3. Complete data recording of three layers of data is recorded in three layers: layer (step layer) / step layer / cycle layer, automatically recording each cell's capacity, internal resistance, pressure difference, and charge/discharge efficiency; Supports batch export of entire containers to MySQL databases for easy quality traceability.
4. During breakpoint continuation, power is cut off or the machine stops; incoming power automatically resumes the previous process, eliminating the need to repartition volumes from scratch, saving labor time
5. Curves can be customized along the X/Y axes, freely matched with time, voltage, and capacity, allowing intuitive viewing of cell discharge platform quality (cells with poor platform are directly eliminated).

5. Complete multi-level safety protection (prevents overcharging, overdischarging, and fire from cells)

1. Voltage upper and lower limits, current upper and lower limits, power and capacity custom protection;
2. Reverse wire connection, disconnection, MOS power transistor breakdown protection, automatic interruption of abnormal channels with no current;
3. Automatic shutdown alarm for voltage jumps, communication disconnections, and program jamming;
4. Automatically disconnects the battery cell when power is cut off, preventing power shock and cell damage;
5. Over-specification alarm: Immediate alert when cell voltage exceeds the device's range

6. Fixtures and Compatible Cells (The Biggest Difference from BT Aging Cabinets)

1. Standard: Battery probe + 60A alligator clip, directly clips a single cell tab, no need to connect to the battery pack;
2. Cell dimensions for suitable formula shape: length < 240mm, width < 75mm, height 65~250mm, tab pitch 40~170mm, single cell weight ≤8KG;
3. Comparison BT100V50A: BT connects a finished battery pack (multi-series module), while BF only has a single bare cell.

7. Energy feedback and energy-saving instructions

8. Optional fittings, accessories, and wear parts

1. Standard accessories: complete unit, software, 5-meter three-phase five-wire power cable, network cable, 60A alligator clip;
2. Wear parts (not covered by warranty): 60A probe, alligator clip; battery cells worn out by long-term clamping, replace regularly;
3. No documentation indicating BMS optional: This unit only tests a single bare cell and does not require a BMS protection board, unlike BT module cabinets that support 485/CAN communication.

9. Summary of applicable scenarios for the equipment

1. Cell factories: new cell formation, capacity grading, and grading;
2. Cascade battery factories: Testing and screening the capacity of old large cells per cell;
3. R&D laboratory: testing the cycle life, rate of square cells, and platform performance;
4. Prohibited use: Do not directly test 48V/60V series battery packs (maximum voltage 5V, connect to module for direct overvoltage protection).
