Pourquoi le Model Y 2024 a-t-il moins d'autonomie ?

Summary

In this insightful video from Tesla Geek, the host addresses common concerns of Tesla Model Y owners regarding discrepancies in displayed battery range. They explain the difference between WLTP and EPA testing standards, noting that Tesla uses the more rigorous EPA cycle for range calculations. The video also highlights new regulations affecting autonomy display for 2024 models and reassures viewers that actual battery performance remains unchanged. Additionally, the host emphasizes the importance of monitoring battery health and how to calculate it using the displayed autonomy values. This video is essential for Tesla enthusiasts looking to better understand their electric vehicles.

Takeaways

• 😀 Many new Tesla owners express confusion over the displayed range compared to the advertised WLTP figure, leading to concerns about battery issues.
• 😀 Tesla uses the EPA cycle, which is more stringent than WLTP, to calculate the displayed range, explaining discrepancies in expected versus shown kilometers.
• 😀 The WLTP (Worldwide Harmonized Light Vehicles Test Procedure) is the standard for measuring vehicle range under controlled conditions, ensuring comparability between manufacturers.
• 😀 Factors affecting the range displayed in electric vehicles include driving style and conditions; switching from urban to highway driving can drastically reduce range.
• 😀 Tesla’s calculation method for range involves dividing battery energy by a standard consumption rate rather than real-time consumption, leading to potential confusion.
• 😀 New regulations in the U.S. require manufacturers to report electric vehicle range based on the default driving mode, affecting displayed values for 2024 models.
• 😀 The change in displayed range from 2023 to 2024 models does not indicate a decrease in actual battery capacity but reflects updated calculation methods.
• 😀 The displayed range serves as a benchmark for assessing battery health over time, especially important for potential resale value.
• 😀 To check the state of battery health, owners can divide the current range by the original range when the vehicle was new.
• 😀 Regularly calibrating the battery by fully charging it and allowing it to rest is recommended for optimal performance and accurate range reporting.

Q & A

What is the main concern of new Tesla Model Y owners regarding displayed autonomy?

New Tesla Model Y owners often express concern about the discrepancy between the expected autonomy (e.g., 455 km) and the actual displayed range (e.g., 394 km) after charging.

What does WLTP stand for, and how does it relate to vehicle autonomy?

WLTP stands for Worldwide Harmonised Light Vehicle Test Procedure. It is a standard testing method that manufacturers must follow to measure and report vehicle autonomy, ensuring comparability between different brands.

How does Tesla calculate the autonomy displayed in their vehicles?

Tesla calculates autonomy based on the energy available in the battery divided by a standard consumption figure, using the EPA cycle rather than the WLTP standard.

Why do some Tesla users find the autonomy displayed in their cars confusing?

New Tesla owners, lacking experience with electric vehicles, may find the displayed autonomy confusing, especially when it is lower than expected due to the differences in testing standards and driving conditions.

What should users check if they have questions about their Tesla's autonomy?

Users should refer to the vehicle's manual, which contains information about autonomy calculations, and they can also conduct a quick Google search for additional clarity.

What change occurred in the 2024 models regarding autonomy measurement?

Starting in 2024, new regulations require manufacturers to measure electric vehicle autonomy based on the default driving mode, which affects the displayed autonomy figures for newer Tesla models.

How can Tesla owners measure the health of their battery using displayed autonomy?

Owners can measure battery health by charging it to 100% and then dividing the current displayed autonomy by the original autonomy figure to calculate the state of health.

What does a lower displayed autonomy in newer Tesla models indicate?

A lower displayed autonomy in newer models does not indicate a degradation in battery performance but rather reflects changes in how manufacturers are required to calculate autonomy under new regulations.

How often should LFP batteries be calibrated according to Tesla guidelines?

Tesla recommends calibrating LFP batteries at least once a week by charging to 100%.

What is the recommended action for drivers if the GPS estimates battery levels drop below 5%?

Drivers should begin to worry if the GPS estimates battery levels drop below 5% and may need to slow down to ensure they reach their destination safely.
