Recently, a Tesla owner shared a way to view Tesla's backend information through the "Dyno test" state, and many car owners revealed their battery loss.

A few days ago, a Tesla owner shared the method of to view Tesla's backend information (at the end of the specific tutorial) in the "Dyno test" state. Many car owners have revealed the battery loss situation.

Some car owners said that 's own long-range four-wheel drive version Model Y has currently traveled 12,000 kilometers, and the attenuation data displayed in the background is 2.8%. It is reported that the long-range four-wheel drive version of Model Y is equipped with a 76.8kWh ternary lithium battery and a NEDC range of 594 kilometers.

vs. ternary lithium battery , Tesla equipped with iron phosphate lithium battery seems to have smaller attenuation. Some car owners posted data showing that has driven 20,000 kilometers of standard range upgraded version of Model 3, and the current attenuation of the battery is almost 0. The attenuation of

lithium battery shows a trend of rapid initial stage and slowing down later stage. Currently, the problem of Tesla battery attenuation of is not serious. According to early Model S and Model X data, when vehicles drive to 150,000 miles (240,000 kilometers), the battery loss of most vehicles is between 8% and 15%.

experimental data show that most lithium iron phosphate batteries cycle life is more than 3500 times, and some can even reach 5000 times, while ternary lithium batteries are relatively few, about 2000-2500 times. Under the same number of cycles, the remaining capacity of lithium iron phosphate batteries is much greater than that of ternary lithium batteries, and the real life is longer.

If the electric vehicle is charged once every 5 days as a complete charge and discharge cycle, the life of the ternary lithium battery can exceed 10,000 days (about 30 years). However, the actual use is still different from the theory. If the ternary lithium battery undergoes 1,000 charge and discharge cycles, it has basically decreased by 50% and the mileage will be shortened to half.

Domestic Tesla currently implements battery warranty policies in China. Depending on the model, has two situations: 8 years or 160,000 kilometers (whichever comes first) and 8 years or 192,000 kilometers (whichever comes first). Tesla guarantees that the battery has a minimum battery capacity of 70% during the warranty period.

For the practice of judging battery attenuation in the "Dyno test" state, Tesla stated: data is a instantaneous value read in real time, not the real degree of attenuation of the battery, and it only has a certain reference significance. regarding the attenuation clause of the battery warranty of no less than 30%, the official will have a more accurate way to diagnose the battery, and read the battery data through strict diagnostic procedures to judge the degree of attenuation.

The specific operation steps for viewing Tesla Dyno test background information are:

1. Open the door from the car while locking the car and press the brake pedal (step it and release it);

2. Click on the software, press and hold the "3" in "Tesla 3" on the screen for a few seconds until the screen ripples appear, and then the dialog box appears on the screen;

3. Enter the password dynotest in the dialog box, and lightly dial the left turn signal (not flashing) to enter
