Autonomy and consumption of electric vehicles
Find out which factors influence consumption and increase the range of your electric vehicle
How to get better autonomy for your electric vehicle
- Using regenerative braking
- Check tyre pressure
- Always recharge the battery
- Do not accelerate excessively
- Use the air conditioner as little as possible
It is possible to increase the range of electric vehicles by using a few tricks. Here are some simple tips to help you increase the autonomy of electric vehicles and how much you can increase it if you use them. When braking, release the accelerator in good time and only use the brake if necessary, so that you can make the most of regeneration: +15% autonomy. Check tyre pressure: +5% range. Always recharge your vehicle batteries before your work shift, so your battery is at its best before you leave: + 3% range. Do not accelerate too much unless it is really useful: +3% range. In the summertime, instead of turning the air conditioner on, open the front windscreen, which is not annoying and increases comfort considerably: + 10% autonomy.
The main parameters influencing range in electric vehicles
The autonomy of electric vehicles is influenced by multiple parameters, as it is normally the case with combustion vehicles. These parameters can alter vehicle performance and efficiency significantly. Driving style, tyre type and cargo bed load all have a major influence on the autonomy of both vehicle categories (electric and combustion). However, there are other parameters that affect vehicle types differently. This is the case with the frequent use of "stop and go" which, in the case of diesel/petrol vehicles, leads to a significant reduction in vehicle range, whereas in electric vehicles (which recover energy when braking) the impact on autonomy is much smaller. Another factor affecting the autonomy of both vehicle categories is air conditioning. Let's take a closer look at the factors specific to electric vehicles.
Factors influencing the autonomy of an electric vehicle
The declared autonomy of Alkè ATX electric vehicles is based on an ambient temperature of 25° on a flat asphalt road, summer tyres and 28% load capacity (WLTP certified cycle). The electric motor only consumes energy when moving. When the vehicle is stationary, the only consumption comes from auxiliary elements such as the heating or air conditioning, if active. The frequent stop-and-go that can occur in the city is favourable to the electric vehicle, which recharges through regenerative braking. In fact, Alke electric vehicles use regenerative braking to obtain the maximum performance from the batteries, which allows a maximum saving of about 30%. By choosing a high-capacity battery, or the rapid-charging system for lithium batteries or the multiple quick-change battery system, your vehicle will still be ready for use in no time at all.
Let's take a practical example: Flatbed vehicle with 20 kWh lithium battery - load 100 kg on the platform - summer tyres - air conditioning (2 hours per day) - temperature 27 °C. Total load on vehicle (100 kg) = -3% - Air conditioning = (2x7) -14%. Effective range at 25 °C = 200x0.97x0.86= 166.84 km.
