  • Test Type: Reliability Test (Thermal / Temperature Rise)
  • Standard: Internal standard (no external specification)
  • Ambient Temperature: 28.07 °C across all samples
  • Highest Motor Tail Temperature: 96.73 °C (P200-9#)
  • Highest Motor Temperature: 84.29 °C (P200-9#)
  • Highest Battery Temperature: 44.61 °C (P200-9#)
  • Verdict: For Reference Only (■供参考)

Test Procedure

  1. Pre-test: Confirm samples (P200-7#, P200-8#, P200-9#) are fully charged and placed in an ambient-temperature environment (~28 °C).
  2. Setup: Connect the product to a 4 psi load. Attach temperature monitoring probes to the motor tail, motor body, and battery positions.
  3. Procedure: Start the pump and allow it to run continuously under the 4 psi load. Continuously record motor tail temperature, motor temperature, and battery temperature throughout the run.
  4. End condition: Continue operation until the battery is fully depleted.
  5. Post-test: Record the peak (maximum) temperature and temperature rise (ΔT in Kelvin) for each monitored point on each sample.
  6. Acceptance criteria: No external pass/fail threshold specified; results recorded for reference only per internal standard.

Test Data & Results

Sample No. Measurement Motor Tail Temp. Motor Temp. Battery Temp. Ambient Temp. (°C)
P200-7# Max Temperature (°C) 79.52 75.48 40.06 28.07
Temperature Rise (K) 28.07 47.41 11.99
P200-8# Max Temperature (°C) 80.99 76.18 41.45 28.07
Temperature Rise (K) 52.92 48.11 13.38
P200-9# Max Temperature (°C) 96.73 84.29 44.61 28.07
Temperature Rise (K) 68.66 56.22 16.54

Observations: P200-9# recorded the highest temperatures across all three monitoring points. Motor tail temperatures exceeded motor body temperatures for all samples, indicating the tail end is the hottest zone during continuous operation. Battery temperatures remained moderate (40–45 °C max), well below typical lithium cell thermal-runaway thresholds. Temperature rise values for P200-8# and P200-9# show meaningful unit-to-unit variation at the motor tail (52.92 K vs 68.66 K), which may warrant further investigation in a larger sample set.

Frequently Asked Questions

What does ‘For Reference Only’ mean in this report?

The verdict ‘■供参考 (For Reference Only)’ indicates that no external pass/fail threshold exists for this test parameter under the applicable internal standard. The data is captured as engineering reference to benchmark thermal performance across units and across product revisions, rather than to certify compliance with a regulatory limit.

Why is the motor tail temperature higher than the motor body temperature?

The motor tail is the rear end-cap of the motor assembly, which is in closest proximity to the pump’s drive mechanism and experiences concentrated friction and electromagnetic losses during operation. With limited airflow in that zone, heat accumulates faster at the tail than at other parts of the motor housing.

Is a battery peak temperature of 44.61 °C safe for lithium cells?

Yes. Standard lithium-ion and lithium-polymer cells are rated for continuous operation up to 60 °C and have protection circuits that trigger above approximately 70–80 °C. A peak of 44.61 °C under a full discharge cycle is within a comfortable safety margin, though ongoing monitoring across ambient extremes (e.g., 40 °C+ environments) is advisable.

What load was used during the test?

All three samples were tested under a constant 4 psi back-pressure load, which simulates the resistance the pump encounters when inflating a sports ball to a typical target pressure. The pump ran continuously from a full charge until battery depletion under this condition.
