Range measurement tests for electric vehicles
Laboratory and road tests
Accurately assess the real range of your electric vehicles
Why measure the range of an electric vehicle?
Range is one of the decisive criteria for evaluating an EV. Rigorous measurement makes it possible to :
- Precisely quantify the distance that can be covered on a full charge.
- Check regulatory compliance with certification standards (WLTP, EPA, etc.).
- Compare different models or battery/motor configurations.
- Communicate transparently to end users.
- Identify areas for technical optimisation (energy management, charging strategy, energy recovery).
What parameters are measured for an electric vehicle?
- Distance travelled on a full charge (km).
- Energy consumed (Wh/km or kWh/100 km).
- BMS behaviour (low voltage cut-off, power limitations).
- Overall energy efficiency of the vehicle.
- Impact of auxiliaries (heating, air conditioning, lighting, etc.).
Test methodology
We carry out tests using several complementary approaches.
Laboratory tests on air-conditioned roller bench
- WLTP cycle (Worldwide Harmonized Light Vehicle Test Procedure): European reference protocol.
- EPA cycle (United States), JC08 (Japan), Artemis on request.
- Controlled simulation of the environment: temperature, rolling resistance, on-board weight.
- Evaluation of electricity consumption (Wh/km) and mileage obtained per complete battery cycle.
Real Road Tests (RDE)
- Reproduction of urban, suburban and motorway routes.
- On-board instrumentation for precise measurement of energy consumption, distance travelled and BMS behaviour.
- Takes account of weather conditions, terrain and driving style.
