Electric vehicle performance and consumption evaluation

In this article, the driving performance of two electric vehicles of the latest generation clean powertrain cars is evaluated. The vehicles under test are an electric Peugeot iOn, and an AGV electric version of the Ford Transit Connect. For different torque-speed operating conditions at wheel level, the vehicles are evaluated for their battery to wheel - electrical to mechanical - power conversion performance, with the help of chassis dynamometer testing. This generates an insight in the mapping of the consumption and efficiency value ranges for electric driving. The vehicles are also tested in real life on-road conditions, by following a pre-set representative track on public roads. Charging efficiency and consumption of auxiliaries is considered too. These tests give insight and realistic values to judge consumption, driving range and efficiency. With these results, further calculations and accurate simulations of realistic scenarios are possible.
