Test Procedure

  1. Pre-Test: Verify each sample (1#, 2#, 3#) is fully charged before the first discharge round.
  2. Setup: Connect the 0.6 L cylinder to the C2 unit. Set target pressure to 150 psi starting from 0 psi.
  3. First Discharge Round (第一次放电测试): Run the unit through consecutive inflation cycles. Record elapsed time (in fractional days) for each cycle. Continue until the battery is exhausted. Record the total number of completed cycles.
  4. Recharge: Fully recharge each sample unit before proceeding to the second round.
  5. Second Discharge Round (第二次充满放电测试): Repeat the cyclic inflation procedure under identical conditions. Record elapsed time for each cycle and total cycle count until battery exhaustion.
  6. Post-Test: Inspect each sample for physical anomalies. Record all cycle times and counts in the data sheet.
  7. Acceptance Criteria: Each sample must complete multiple cycles in both rounds; elapsed time per cycle should increase monotonically, reflecting normal battery depletion under repeated high-pressure load.

Observations (Round 1): All three samples show a consistent upward trend in per-cycle elapsed time, confirming progressive battery depletion under repeated 0–150 psi loading. Sample 2# completed 7 cycles before exhaustion; samples 1# and 3# each completed 8 cycles.

Observations (Round 2): After a full recharge, all samples again demonstrated monotonically increasing cycle times. Sample 1# extended to 9 cycles in this round; samples 2# and 3# completed 8 cycles each. Cycle times in Round 2 are generally comparable to Round 1, indicating consistent battery capacity retention between charges.

Frequently Asked Questions

What does the ETENWOLF C2 high-pressure cyclic discharge test measure?

The test measures how many consecutive inflation cycles the C2 can complete when pressurizing a 0.6 L cylinder from 0 to 150 psi on a single battery charge. Elapsed time per cycle is recorded to track battery depletion under repeated high-pressure load.

How many cycles did the ETENWOLF C2 complete in the discharge test?

Across two discharge rounds, the three test samples completed between 7 and 9 cycles each. In Round 1 (first discharge): 1# completed 8 cycles, 2# completed 7, and 3# completed 8. In Round 2 (after full recharge): 1# completed 9 cycles, 2# completed 8, and 3# completed 8.

Why do cycle times increase with each successive cycle in the C2 discharge test?

As the battery depletes under repeated high-pressure load, the motor delivers slightly less power per cycle, causing each successive inflation cycle to take marginally longer. A monotonically increasing time trend is the expected and normal result, confirming the battery is discharging progressively rather than failing abruptly.

Is the ETENWOLF C2 battery capacity consistent between charges?

Yes. The Round 2 discharge results (after a full recharge) show cycle counts and per-cycle times comparable to Round 1, indicating stable battery capacity retention between charge cycles for all three samples tested.
