Tesla begins using new parameters like wind direction 

According to the latest report, Tesla has started to use new parameters such as wind, air density, and humidity to calculate a more accurate range for its electric vehicles.

Moreover, according to hacker @greentheonly, the 2022.8.2 software update released this week includes an unmentioned change: the trip planner now takes into account crosswind/headwind, air density, and humidity.

The hacker also said that the feature may currently only be available in China. It’s unclear how the trip planner measures and uses these variables, but it’s easy to understand how wind direction affects electric vehicle range, and taking it into account makes Tesla’s estimated range more accurate.

Furthermore, Tesla added more parameters to estimate the cruising range in 2018, including altitude changes, weather, etc. Tesla drivers can enter their destination into the car’s interactive system to determine if they have enough power to complete the trip. 

These estimates may vary slightly due to external factors such as weather. The new feature could improve the accuracy of mileage predictions by several percentage points.
