Test Equipment & Setup
| Parameter | Value |
|---|---|
| Test Equipment | Power Supply (电源) |
| Ambient Temperature | 23 °C |
| Relative Humidity | 60 % |
| Life Target (Standard) | 10 H charge-discharge cycles (充放电寿命标准 10H) |
| Charge Duration (observed) | Approx. 1 hour 20 minutes per cycle |
| Discharge Duration (observed) | Approx. 15 minutes per cycle |
| Total Test Run Logged | 13 hours |
| Acceptance Criterion | No failure of function; stable operation throughout (确保功能无失效，观察其稳定性) |
Test Procedure
- Pre-test: Fully charge all three samples (S0-6#, S0-7#, S0-8#) before starting the endurance run.
- Cycle start: Begin discharge by running the pump continuously until battery is fully depleted.
- Recharge: Reconnect to power supply and recharge until full; record charge duration (~1 h 20 min per cycle).
- Repeat cycles: Continue charge-discharge cycles targeting a cumulative run time of at least 10 hours (internal life standard).
- Monitoring: Observe samples throughout aging for thermal events, error codes, and functional anomalies. Log any E14 (high-temperature protection) or other fault codes.
- Post-test inspection: After aging, verify inflation accuracy and time for each sample; inspect exterior appearance for any physical defects.
- Acceptance criteria: All samples must complete 10 H of charge-discharge operation with no functional failure and stable performance throughout the aging process.

Overall Test Result: At 19 hours of life aging, 1 sample was unable to inflate; 1 sample exhibited an E21 fault code. (测试结果：样品寿命老化到19小时有1个样品出现打不上气的现象，有1个出现E21的现象。)
Conclusion
| Field | Details |
|---|---|
| Result | For Reference Only (供参考) |
| Standard | Internal Control Standard — 10 H charge-discharge life |
| Test Conditions | 23 °C, 60 % RH; power supply; 13 H logged run |
| Samples Tested | 3 PCS (S0-6#, S0-7#, S0-8#) |
| Verdict | Not Pass / Not Fail — For Reference Only. Samples exceeded the 10 H internal target (13 H logged) but sample 6# lost inflation capability at 19 H and one sample showed E21. Data retained for engineering reference. |

Frequently Asked Questions
What does the ETENWOLF S0 life cycle test measure?
The test evaluates the reliability of the S0 motor over repeated charge-discharge cycles. Samples run until battery depletion, are recharged, and the cycle repeats for a minimum of 10 hours per the internal control standard. Performance, error codes, and inflation accuracy are recorded throughout.
Why is the ETENWOLF S0 endurance test result classified as For Reference Only rather than Pass or Fail?
The result is classified as For Reference Only because, while all three samples exceeded the 10-hour life target (logging 13 hours), sample 6# lost the ability to inflate when aging reached 19 hours and one sample triggered an E21 fault. The data is retained for engineering review rather than used as a definitive pass/fail quality gate.
What error codes appeared during the S0 aging test?
Two fault codes were observed: E14 (high-temperature protection), which appeared intermittently across samples during the aging run, and E21, which appeared on one sample after extended cycling. Both were logged as part of the test observations.
What was the inflation accuracy of the S0 after 13 hours of aging?
Post-aging inflation accuracy remained close to target for all three samples: S0-6# reached 110.1 psi in 2 minutes 2 seconds; S0-7# reached 110.2 psi in 2 minutes 35 seconds; S0-8# reached 110.2 psi in 2 minutes 38 seconds. Appearance showed no physical defects after aging.
