| Test No. | — |
| Sample Quantity / No. | 2 PCS |
| Type of Test | Reliability Test |
| Test Standard | Internal Standard |
| Test Purpose | Monitor the temperature of the motor and battery during product operation |
| Acceptance Criterion | Evaluate the performance stability of sample temperature variation |
Test Equipment & Setup
| Item | Detail |
|---|---|
| Test Equipment | Thermal Rise Tester (温升测试仪) |
| Ambient Temperature | 27.5 °C (room temperature) |
| Initial Battery State | Fully charged |
| Termination Condition | Battery fully discharged |
| Monitored Points | Battery, Motor, Air Nozzle (气嘴), Cylinder (气缸) |
| Temperature Unit | °C (peak) / K (rise above ambient) |
Test Procedure
- Pre-test: Charge both P300 samples to full capacity and allow them to reach room temperature (27.5 °C).
- Sensor placement: Attach thermal rise tester probes to the battery, motor, air nozzle, and cylinder measurement points on each sample.
- Run: Power on each sample and operate continuously, recording temperature at each monitoring point throughout the run.
- Termination: Continue operation until the battery is fully discharged and the unit stops automatically.
- Post-test: Record the peak temperature and calculate the temperature rise (K) for each monitored point by subtracting the ambient temperature (27.5 °C) from the peak reading.
- Evaluation: Compare results against the acceptance criterion of stable temperature variation performance.
Test Data & Results
| Sample No. | Measurement | Battery Temp (°C / K) | Motor Temp (°C / K) | Air Nozzle Temp (°C / K) | Cylinder Temp (°C / K) | Ambient Temp (°C) |
|---|---|---|---|---|---|---|
| P300-7# | Peak Temperature (°C) | 50.2 | 53.1 | 57.1 | 51.1 | 27.5 |
| Temperature Rise (K) | 22.7 | 25.6 | 29.6 | 23.6 | ||
| P300-8# | Peak Temperature (°C) | 48.3 | 62.1 | 38.9 | 57.4 | 27.5 |
| Temperature Rise (K) | 20.8 | 34.6 | 11.4 | 29.9 |
Observations: P300-7# showed the highest air nozzle peak (57.1 °C, +29.6 K). P300-8# recorded the highest motor peak (62.1 °C, +34.6 K) but a notably lower air nozzle peak (38.9 °C, +11.4 K), suggesting unit-to-unit variation in heat distribution between the motor and nozzle path. All readings are within ranges consistent with continuous full-discharge operation. Detailed time-series data is recorded on the companion sheet (温升数据 / Thermal Rise Data).
Conclusion
| Field | Detail |
|---|---|
| Overall Result | For Reference Only (供参考) |
| Standard Applied | Internal Standard |
| Test Conditions | Full charge to full discharge; ambient 27.5 °C; continuous operation |
| Samples Tested | P300-7#, P300-8# (2 PCS) |
| Verdict | Both samples completed the full-discharge run. Temperature data has been captured for reference and further product evaluation. No formal pass/fail threshold was applied under the internal standard. |

Frequently Asked Questions
What does the ETENWOLF P300 thermal rise test measure?
The test monitors the peak temperature and temperature rise (in Kelvin above ambient) at four points — battery, motor, air nozzle, and cylinder — while the P300 runs continuously from a full charge until the battery is exhausted. This reveals how heat builds up during worst-case sustained use.
What were the highest temperatures recorded during the P300 thermal test?
Across both samples, the highest motor temperature was 62.1 °C (temperature rise 34.6 K) on unit P300-8#, and the highest air nozzle temperature was 57.1 °C (rise 29.6 K) on unit P300-7#. The ambient temperature during testing was 27.5 °C.
Why is the P300 thermal report marked “For Reference Only” rather than Pass or Fail?
The test was conducted against an internal standard designed to characterize temperature behaviour, not to enforce a specific limit. The “For Reference Only” designation means the data is used to inform product development and quality benchmarks rather than to make a binary compliance judgement.
Where can I find the full time-series thermal data for the P300?
The detailed data logged at each time interval during the discharge run is recorded in the companion sheet 温升数据 (Thermal Rise Data), which is the second sheet in the same test workbook. A cross-link to that article is available in the Related Products section below.
