What factors can affect my electric vehicle’s range?
There are a number of factors that can affect the range achieved by an electric vehicle (EV) on a full charge, and are often stated on manufacturer websites and literature. These include:
- The weather and climatic conditions
For example, in colder temperatures, the range will decrease as the battery is able to hold less charge, and there may be greater usage of climate control systems.
- Terrain and topography
For example, driving on steeper inclines or on rougher ground, means that the motors on the wheels have to work harder to drive the wheels, thereby using more power from the battery, and reducing range per full charge.
- Driving style
The speed of acceleration and driving at higher speeds can all influence range, as they draw a greater charge from the battery over shorter periods of time.
- Load
Carrying luggage, and the number of occupants in the car can impact the level of range, as the heavier the car, the more power is needed to drive the vehicle’s wheels when in motion.
- Tyre pressures
Tyres on EVs are generally subject to a greater level of wear than those found on similar petrol or diesel models, due to electric cars often being heavier.
Also, the degree to which tyres are inflated compared to what is recommended by the manufacturer, can impact range. For example, under-inflated tyres generate greater rolling resistance and diminish the level of range as the motors have to work harder.
- The age of the battery
Over time, the capacity of the battery to hold a full charge decreases, thereby decreasing the achievable level of range per full charge.
Please note that the factors affecting range that have been highlighted in this article are not exhaustive.
