Geotab Analysis: This is How Much Temperature Affects the Range of Electric Cars

Geotab presents a new analysis on the range of electric vehicles, examining the influence of speed and temperature.

The interactive analysis, presented for the first time at Geotab Connect 2023, uses anonymized, aggregated data from three million electric vehicle trips and 550,000 hours of driving time to better understand the relative impacts of temperature and speed on range.

Confidence in the range of electric vehicles is crucial for widespread adoption. The analysis allows users to investigate two key factors that affect range: ambient temperature and the aerodynamic drag of a vehicle at different speeds. Understanding the functional range of an electric vehicle helps strengthen confidence in the efficient operation of the vehicles and aids in selecting the right vehicle for a specific task and current conditions. The analysis compares the range of two vehicle types by modeling an electric sedan and a light-duty van, both set to a 65-kWh battery.

Interesting: Temperature is more relevant at lower speeds

The analysis found that vehicle speed affects the impact of temperature: At low speeds, temperature has a significant effect on range, while at higher speeds it is much less relevant. Vehicle size and shape also influence the optimal conditions for maximizing electric vehicle range. These findings show that strategies to optimize electric vehicle range should consider the context of the planned trip.

As expected: On highway drives, excessive speeds should be avoided, especially for larger vehicles. On slower routes, seasonal fluctuations in range are greater, so the best results are achieved when the impacts of temperature are mitigated. “Electrification is an important component in reducing CO2 emissions in fleets. To help companies integrate electric vehicles into their fleets, Geotab provides data to enable informed decision-making,” says Klaus Böckers, Vice President Nordics, Central and Eastern Europe at Geotab, and adds:

“The analysis, based on real vehicle data, is intended to help users understand the factors that affect EV range and raise awareness of strategies to optimize electric vehicles.”

Data helps to analyze the fleet much more accurately

With one of the largest data science teams in the industry and the processing of more than 100,000 data points per second, Geotab has the expertise and resources to support fleet managers in solving today's challenges and planning for the world of tomorrow. Geotab is committed to helping fleets accelerate their CO2 reduction and offers informational materials and a range of innovative tools in its Electrification Knowledge Center, based on one of the largest datasets of real-world EV performance data, to help businesses make smart and sustainable decisions that are in the best interest of both their operations and the environment.

What does this mean?

Geotab now has so much data that it can be used to analyze and evaluate detailed dependencies and impacts of driving routes and temperatures - even simultaneously. Due to the volume of data, Geotab can also use it for simulations and modeling of new models.
