Efficiency of Electric Vehicles in Low-Speed Driving
Electric vehicles have a significant advantage over internal combustion vehicles when it comes to driving at low speeds around town. The slower the driving speed, the lower the energy consumption for EVs. This efficiency is one of the key factors that make EVs a more sustainable option for everyday commuting. However, it raises the question of how much energy an EV consumes while switched on and standing still, especially in freezing conditions.
Conducting the Experiment: Testing the Tesla Model 3 in Freezing Temperatures
To determine the energy consumption of an EV while idling, a Canadian YouTuber named FrozenTesla conducted an experiment using his own 2024 Model 3 Long Range All-Wheel Drive. The test simulated a scenario where a driver is stranded and needs to keep warm. The experiment involved keeping the car on through a freezing night when temperatures felt as low as -28 C (-18 F) degrees, with the climate control system, heated seats, and steering wheel all activated.
Results of the Experiment: Energy Consumption and Cost Analysis
The experiment began with the car’s battery state of charge at 66%, and over the course of 12 hours, the battery level decreased to 29%. The average energy loss per hour was calculated to be 3%, resulting in the consumption of 34.4 kWh of energy. Considering the average electricity price of $0.176 per kWh in the U.S., the total cost of idling the EV for 12 hours was $2.11, making it a much more cost-effective option compared to a gas-powered vehicle.
Cost and Environmental Impact of Idling Gasoline-Powered Cars
In comparison, a four-cylinder 1.5-liter gas engine consumes approximately 0.16 gallons of fuel per hour when idling. Over 12 hours of idling, this amounts to 1.92 gallons of fuel being used. Given the average gas cost of $3 per gallon in the U.S., the total cost of idling a gasoline-powered car for the same duration would be $36. Additionally, idling a gas engine for extended periods can have negative effects on its health, leading to contamination of engine oil and increased emissions.
Environmental Benefits of Electric Vehicles
One of the major advantages of leaving an EV to "idle" is the absence of emissions associated with it, provided that the energy used to charge the batteries comes from green sources. This contrasts with idling a gas engine, which emits harmful gases into the environment. Overall, opting for an electric car in stranded situations can significantly reduce energy consumption and environmental damage compared to a gas-powered vehicle.
Conclusion: Choosing Electric Vehicles for Sustainable and Cost-Effective Driving
In conclusion, the experiment with the Tesla Model 3 showcased the efficiency and cost-effectiveness of electric vehicles, even in extreme weather conditions. With lower energy consumption, reduced emissions, and lower operating costs, EVs present a more sustainable option for everyday commuting and emergency situations. Choosing electric vehicles over traditional gasoline-powered cars can lead to a greener and more cost-effective future for transportation.
