Hiver en VE : Autonomie réduite ? Usage dégradé ? Je teste !

Summary

In this episode, the host embarks on a road trip to test the winter performance of their Tesla Model S 75D, comparing it to previous summer results. They aim to debunk myths about electric vehicle (EV) efficiency in cold weather by measuring real-life consumption and range. Equipped with a 85 kWh battery, the car shows a minimal degradation after 6.5 years and 138,000 km. Despite facing challenging conditions like rain and wind, the test reveals a 13% increase in consumption from summer, offering insights into EV performance nuances across different seasons. The host also discusses the technical aspects of EV energy use in cold weather, emphasizing the impact of external conditions on battery efficiency and range.

Q & A

What was the main purpose of the video?

The main purpose of the video was to test the autonomy and energy consumption of a Tesla Model S in winter conditions and compare it to previous summer test results.

What model of Tesla was tested in the video?

The Tesla Model S 75D from 2017 was tested in the video.

What was the original and residual battery capacity of the Tesla Model S at the time of the winter test?

Originally, the Tesla Model S had an 85 kWh battery, but it was electronically limited. At the time of the winter test, the residual capacity was indicated as 75.5 kWh after degradation.

How did the weather conditions during the winter test compare to the summer test?

During the winter test, conditions included a headwind for parts of the journey, rain, and an average temperature of 8 degrees Celsius, which was less ideal compared to the summer test's ideal conditions of 30 degrees Celsius and no wind.

What was the result of the winter test in terms of energy consumption?

In the winter test, the energy consumption was higher, with a reported 13% increase in energy usage compared to the summer test.

What tools were used to measure the Tesla's performance in the test?

The tools used for measurement included the 'Scan My Tesla' app, which takes information directly from the car's Battery Management System (BMS), and the car's own display metrics.

How did the use of winter tires affect the Tesla's performance in the test?

The use of winter tires, specifically the Hakkapeliitta winter tires, likely influenced energy consumption and was one of the variables considered in the test.

What was the reason behind the increased energy consumption during the winter test?

Increased energy consumption during the winter test was attributed to several factors including lower temperatures requiring more energy for heating, adverse weather conditions like rain and wind, and possibly the use of winter tires.

How did the video address the impact of real-world conditions on electric vehicle performance?

The video highlighted that real-world conditions such as weather, road conditions, and driving habits can significantly influence electric vehicle performance, particularly energy consumption and autonomy.

What was the final conclusion of the winter test in terms of Tesla Model S's autonomy?

The final conclusion was that despite a 13% increase in energy consumption in winter conditions, the Tesla Model S still demonstrated decent autonomy, with careful planning around charging infrastructure mitigating the impact of increased energy use.
