The Atomfair-BTS-724 must be operated within 0-40°C and ≤70% RH non-condensing, and stored at -10-50°C with ≤80% RH. The unit uses AC 220V ±10% 50Hz input power and has IP20 protection, requiring installation in a clean, dry environment free of conductive dust and moisture.

  • Temperature Range: Operating temperature must be maintained between 0°C and 40°C; storage temperature between -10°C and 50°C.
  • Humidity Limits: Operating humidity must not exceed 70% RH, and storage humidity must not exceed 80% RH, both without condensation.
  • Electrical Input: The unit requires a stable AC power supply of 220V ±10% at 50Hz; use a dedicated, grounded outlet.
  • Enclosure Rating: IP20 rating indicates protection against solid objects larger than 12mm but no water ingress protection; avoid liquid exposure.

This procedure outlines the safe initialization, configuration, and execution of a battery test cycle using the 8-channel battery tester. Follow each step sequentially to ensure accurate measurements and prevent damage to the device or batteries.

Required Equipment: Atomfair-BTS-724 Battery Tester, 4-wire test leads with Kelvin connections, Windows-based PC with Atomfair software installed

  1. Connect Power
    Connect the tester to an AC power outlet (220V ±10%, 50Hz) using the supplied power cord and ensure the unit is properly grounded.
  2. Connect Battery Cells
    Attach each battery cell to a dedicated channel using 4-wire test leads, ensuring firm and correct polarity connections for voltage and current sensing.
  3. Launch Software
    Open the Windows-based Atomfair software and verify that all 8 channels are recognized and show no error alerts.
  4. Configure Test Parameters
    Set desired charge/discharge modes, cut-off conditions (voltage, current, time, capacity, -ΔV), and cycle settings (up to 65535 cycles with 63 steps per cycle).
  5. Start Test
    Initiate the test sequence and monitor real-time voltage, current, power, and capacity data displayed on the software interface.
  6. Monitor and Modify
    Use the GOTO, restart, or resume functions to adjust parameters or restart cycles without interrupting the test if needed.
  7. Complete and Disconnect
    Disconnect battery cells from each channel after the test completes or when manually stopped, and then power down the tester.

What is the trade-off between using constant current (CC) and constant power (CP) discharge modes for rate capability testing of energy storage materials?

Constant current discharge provides direct current regulation for straightforward rate capability tests, while constant power discharge maintains steady power output by dynamically adjusting current as voltage drops, simulating real-world loads. The BTS-724 offers both modes with voltage and current accuracy of ±0.1% FS and power stability of ±0.2% FS, so CP mode incurs slightly higher uncertainty due to combined voltage and current errors. CC mode is preferred for precise current-controlled protocols, while CP mode is more representative for applications like grid energy storage testing.

Can the 8 independent channels of the Atomfair-BTS-724 be combined in parallel to test a single high-power cell exceeding 20A?

No, the BTS-724's channels are designed to operate independently with their own control circuits and 4-wire connections. Paralleling channels is not supported and would risk current imbalance, compromising the stated ±0.1% FS accuracy and potentially triggering protection limits. Each channel is limited to 20A and 100W maximum, with a total system input power of 1418W, so a single channel cannot be externally boosted.

What are the environmental requirements to ensure accurate operation of the Atomfair-BTS-724?

The BTS-724 must be operated in a temperature range of 0°C to 40°C with relative humidity ≤70% RH (no condensation) to maintain its specified accuracy. Storage conditions allow -10°C to 50°C with ≤80% RH. The IP20 protection rating indicates it is not sealed against moisture or dust, so a clean, dry laboratory environment is essential. Condensation from rapid temperature changes can damage electronics and affect measurement stability.

The Atomfair-BTS-724 Battery Tester provides eight independent high-precision channels with dual closed-loop control and power-off data protection, making it suitable for parallel testing of energy storage cells within 0–5V and 100mA–20A. However, its minimum programmable current of 100mA and 220V AC power requirement limit its use for very low-current applications and in facilities with non-standard electrical infrastructure.

Positive

  • 8 Independent Precision Channels: Each channel operates independently with built-in control circuitry, allowing simultaneous testing of different battery chemistries or conditions with ±0.1% FS voltage and current accuracy.
  • Power-Off Data Protection: The system retains all test data during unexpected power failures, preventing loss of long-duration cycling experiments.

Trade-offs

  • Minimum Programmable Current 100mA: The single-channel output range starts at 100mA, preventing use for low-current tests below that threshold, such as small coin cells.
  • Operating Temperature 0–40°C: The unit is specified for operation only between 0°C and 40°C at ≤70% RH, restricting deployment in unconditioned or extreme environments.
