Test Procedure

Pre-test: Confirm tire is a 215/55R17 passenger car tire. Deflate or adjust tire pressure to the baseline starting pressure of 25 PSI before each run.
Setup: Connect the EV3 inflation pump to the tire valve. Set the target pressure on the pump to 25 PSI and allow the pump to reach and auto-stop at 25 PSI. Then reset the target to 35 PSI.
Inflation run: Start the pump and simultaneously begin timing. The pump inflates the tire from 25 PSI to 35 PSI and automatically stops when the target is reached.
Recording: Record the elapsed time in MM:SS format for each run. Log the unit number (4#, 5#, or 6#) and sequential run number (1–10).
Repeat: Deflate the tire back to 25 PSI and repeat the procedure for runs 2 through 10 for each unit.
Post-test: Compile all timing data. Review for outliers. Compute per-unit averages and overall range.
Acceptance Criteria: All runs must complete successfully with the auto-stop function operating correctly. Timing results are recorded for performance benchmarking; no hard pass/fail time threshold is defined in this internal test.

Observations:

Unit 4# recorded the widest spread, from 01:51 to 02:12, suggesting slightly higher run-to-run variability.
Unit 5# was the fastest and most consistent, with 8 of 10 runs completing under 01:50.
Unit 6# performance was intermediate, with most runs between 01:36 and 02:01, and one outlier at 02:10.
All three units successfully triggered the auto-stop function at 35 PSI on every run.

Frequently Asked Questions

What does the EV3 inflation pump test measure?

This test measures how long the EV3 inflation pump takes to inflate a standard 215/55R17 passenger car tire from 25 PSI to 35 PSI using the pump’s built-in auto-stop feature. The result gives a real-world benchmark for inflation speed under typical use conditions.

Why are three separate units tested with 10 runs each?

Testing multiple units (4#, 5#, 6#) across 10 repeated runs per unit reveals both unit-to-unit variation and run-to-run consistency within a single unit. This approach distinguishes manufacturing variability from random measurement noise, giving a more reliable picture of typical product performance.

What is the auto-stop function and why does it matter?

The auto-stop function allows the user to preset a target pressure; the pump stops automatically when that pressure is reached. This prevents over-inflation, reduces user supervision required, and protects the tire. All 30 runs in this test confirmed the auto-stop triggered correctly at 35 PSI.

How does the 215/55R17 tire relate to the EV3’s intended use case?

The 215/55R17 is one of the most common passenger car tire sizes, making it a representative benchmark for everyday use. Testing with this size ensures the EV3’s inflation speed figures are relevant to the majority of potential users rather than reflecting best-case performance on a smaller tire.
