Quick answer: Use energy, not dashboard kilometres, as the main diagnostic. Record starting and ending state of charge, distance, trip energy or charging energy, temperature, speed, elevation, load, air-conditioning and tyre pressure across at least three comparable runs. A single high-speed or cold or hot trip is not a reliable battery-health test.

Advertised or certified range is not a guarantee for every trip. Measure usable energy and consumption over repeatable routes before blaming the battery.

An action sequence for EV Range Lower Than Claimed

  1. Confirm the range basis

    Separate certified or advertised test-cycle range from owner-estimated dashboard range and real-route range.

  2. Create a controlled route

    Use similar distance, traffic, elevation, speed and climate settings. Start at the same state of charge.

  3. Record energy data

    Capture distance, starting and ending charge, trip consumption, charging energy where available and any battery limits.

  4. Control basic variables

    Set recommended tyre pressure, remove unusual load, check brake drag or alignment symptoms and note ambient temperature.

  5. Compare three runs

    Look for consistent consumption rather than one result. Calculate km per kWh or Wh per km.

  6. Escalate with data

    Provide VIN, software version, odometer, route table, charging logs and diagnostic codes to authorised service.

Range calculation

Trip 120 km uses 24 kWh of estimated usable energy: 5 km per kWh. If usable energy is 40 kWh, comparable range is about 200 km under those conditions. Repeat at a lower controlled speed to quantify aerodynamic impact.
