Motor performance dyno benchmark
Dynamometer + waveform analysis of traction motor.
Our motor performance dyno benchmark package is part of the diagnostics line at ev.care — a flat ₹3,999 for roughly 2 hours of focused workshop time. Dynamometer + waveform analysis of traction motor. The workflow is the same one we use on our own R&D fleet: a stable bay, calibrated tools, and a printed record at the end so you can see exactly what changed. We don't upsell. If the result is "you're fine, come back in a year", that's exactly what we'll write on the report.
What's included
- Dyno torque-speed sweep
- Phase current waveform capture
- Back-EMF check
- Vibration signature recording
- Comparison vs. factory spec sheet
Why this matters
Why owners book this: skipping it risks letting small drift become a stranded vehicle a year from now. A ₹3,999 workshop slot today is the cheapest insurance you can buy against that outcome.
How it works
- 1
Pre-check: tyre pressure, 12V state, and ambient temperature noted.
- 2
Diagnostic harness is connected and a clean session is recorded.
- 3
Subsystems are exercised in a known sequence so anomalies isolate cleanly.
What we typically find
From hundreds of inspections — what makes the report.
- Minor cell imbalance — well within spec, worth re-checking in 6 months
- Stale BMS firmware lagging the current OEM release
- One DTC stored from a prior charging fault, not currently active
- Capacity tracking ~3-7% under nameplate (typical for the age)
- Healthy thermals — no hotspots under load
How to prepare
- Bring the original service book / digital invoice if available
- Note down any specific symptoms with rough time of day
- Plan for about an hour of waiting time at the workshop
- Charge the vehicle to at least 50% the night before
Equipment we use
- Thermal imaging camera (320×240 minimum)
- Insulation-resistance tester (megohmmeter) rated for HV packs
- Manufacturer-grade EV diagnostic scanner
