Test Procedure
- Pre-Test: Verify each sample is fully charged. Record ambient temperature (27.42 °C). Install temperature monitoring probes at battery and motor measurement points. Photograph internal wiring configuration.
- Setup: Connect each sample to a 35 psi load fixture.
- Operation: Start the inflator and run continuously at 35 psi load. Monitor and log battery temperature and motor temperature throughout the run. Photograph the unit during testing.
- End Condition: Continue operation until the battery is fully depleted.
- Post-Test: Record peak temperatures and calculate temperature rise (ΔT = T_peak − T_ambient) for both battery and motor on each sample.
- Acceptance Criteria: No external standard limit is defined (marked “/”). Results are recorded for reference. Any anomalies (smoke, fire, deformation) would constitute failure.
Test Data & Results
| Sample No. | Measurement | Battery Temperature | Motor Temperature | Ambient Temperature (°C) |
|---|---|---|---|---|
| EV3-1# | Peak Temperature (°C) | 55.23 | 50.09 | 27.42 |
| EV3-1# | Temperature Rise (K) | 27.81 | 22.67 | — |
| EV3-2# | Peak Temperature (°C) | 49.28 | 46.50 | 27.42 |
| EV3-2# | Temperature Rise (K) | 21.86 | 19.08 | — |
| EV3-3# | Peak Temperature (°C) | 52.91 | 44.96 | 27.42 |
| EV3-3# | Temperature Rise (K) | 25.49 | 17.54 | — |
Observations: EV3-1# recorded the highest battery peak (55.23 °C, rise 27.81 K) and the highest motor peak (50.09 °C, rise 22.67 K). EV3-2# showed the lowest thermal rise across both measurement points. All values fall within a moderate range with no anomalies reported. Raw time-series data is available on the companion sheet (温升数据). Note: temperature rise values in the source data for EV3-1# (27.809999999999995 K) and EV3-3# (25.489999999999995 K) are floating-point artifacts; rounded values 27.81 K and 25.49 K are used throughout.

Frequently Asked Questions
What temperatures did the ETENWOLF EV3 inflator reach during the thermal rise test?
Under a continuous 35 psi load run from full charge to battery depletion at an ambient of 27.42 °C, the peak battery temperature was 55.23 °C (temperature rise 27.81 K) and the peak motor temperature was 50.09 °C (temperature rise 22.67 K), both recorded on sample EV3-1#.
What does “For Reference Only” mean in this EV3 thermal test report?
The internal test standard used for this report does not define a numeric pass/fail temperature limit. The result is therefore classified as “For Reference Only” (供参考), meaning the data establishes a thermal baseline for engineering review rather than certifying compliance with an external safety standard.
How was the EV3 thermal rise test conducted?
Each of the three EV3 samples was fully charged, then operated continuously under a 35 psi load at room temperature (27.42 °C) until the battery was completely depleted. Temperature probes monitored both the battery and motor throughout the run. Peak temperatures and temperature rises (K) were recorded for each sample.
Where can I find the raw time-series temperature data for the EV3 thermal test?
The detailed time-series temperature logs are contained in the companion sheet “温升数据” (Temperature Data) within the same Excel workbook. A link to the translated 温升数据 article is provided in the Related Products section below.
