Abstract
The paper presents a theoretical analysis of the effect
of electric car performance characteristics on vehicle energy
consumption and driving range. The test object was a Nissan
Leaf electric vehicle. The characteristic curves of basic and additional
resistance to motion (sum of rolling resistance and air
resistance and inertia resistance or grade resistance, respectively)
were applied to the model characteristic curve of electric motor
torque of the tested vehicle.
Based on that, the graphs describing the relationships between
vehicle energy consumption and vehicle speed were made (for
specific values of car acceleration / acclivity grade) as well as the
relations between vehicle driving range and its traction properties.
It was concluded that the use of performance characteristics
significantly increased the vehicle’s energy consumption and
decreased the available vehicle’s driving range.
