| Laboratory Environment | Temperature: 24°C; Humidity: 45% RH |
Test Equipment & Setup
| Parameter | Value |
|---|---|
| Instrument | Constant Temperature and Humidity Testing Machine (恒温恒湿试验机) |
| High-Temperature Condition | 60°C, Humidity 80% RH, duration 2 h |
| Low-Temperature Condition | -20°C, duration 2 h |
| Total Storage Duration | 72 h |
| Post-Storage Functional Test | Power-on check and charging check |

Test Procedure
- Pre-test: Record the laboratory ambient conditions (24°C, 45% RH). Visually inspect all 3 sample units and confirm they are in normal working condition before placement.
- High-temperature phase: Place samples inside the constant temperature and humidity chamber. Set chamber to 60°C and 80% RH. Hold for 2 hours.
- Low-temperature phase: Adjust chamber to -20°C (no humidity control required). Hold for 2 hours.
- Cycle repetition: Repeat the high-temperature and low-temperature phases as programmed. Total cumulative storage time shall reach 72 hours per the program control profile.
- Post-test functional check: Remove samples from chamber. Allow recovery at laboratory ambient conditions. Perform power-on test — unit must start normally with no abnormality. Perform charging test — charging function must operate normally.
- Acceptance criteria: No functional failure. Normal power-on. Normal charging. No physical damage attributable to thermal cycling.
Test Data & Results
| Check Item | Condition | Requirement | Sample 1 | Sample 2 | Sample 3 | Result |
|---|---|---|---|---|---|---|
| High-Temperature Storage | 60°C, 80% RH, 2 h | No failure | Pass | Pass | Pass | Pass |
| Low-Temperature Storage | -20°C, 2 h | No failure | Pass | Pass | Pass | Pass |
| Total Storage Duration | 72 h cumulative | Complete cycle | Pass | Pass | Pass | Pass |
| Power-On Function | Post-test ambient recovery | Normal start-up, no abnormality | Pass | Pass | Pass | Pass |
| Charging Function | Post-test ambient recovery | Normal charging | Pass | Pass | Pass | Pass |
Observations: During the test-in-progress phase, the constant temperature and humidity chamber operated per the program control profile. Post-test inspection confirmed that all samples powered on without abnormality and charged normally. The test result states: samples passed under extreme high/low temperature environmental conditions — no performance abnormality, no functional failure (测试结果：样品在极端高低温环境条件下通过，性能无异常，功能无失效).

Frequently Asked Questions
What temperatures were used in the ETENWOLF S0 thermal shock storage test?
The test cycled between a high-temperature phase of 60°C at 80% relative humidity for 2 hours and a low-temperature phase of -20°C for 2 hours. The total cumulative storage duration across all cycles was 72 hours.
Did the ETENWOLF S0 pass the thermal shock and storage test?
Yes. All 3 sample units passed. After completing the 72-hour thermal cycling program, every sample powered on normally with no abnormality and charged normally. No functional failure was recorded.
What equipment was used to conduct the S0 high/low temperature storage test?
A constant temperature and humidity testing machine (恒温恒湿试验机) was used to control both the temperature and humidity conditions throughout the test program.
Why is thermal shock testing important for a portable bike pump?
A portable bike pump may be stored in a car trunk, garage, or outdoors where temperatures can swing from well below freezing to over 60°C in summer. Thermal shock testing confirms that the battery, motor, and electronics inside the S0 remain fully functional across those extremes, giving users confidence the pump will work when they need it.
