Car Things on December 30th, according to foreign media Insideevs, a foreign car blogger recently evaluated the battery performance of Tesla 2022 Model S Plaid. It was found that the battery of 2022 Model S Plaid has multiple improvements, and the energy density of the power battery is higher than that of old models.
The auto blogger pointed out that the battery pack of the 2022 Model S Plaid should receive more attention. “It (the battery pack of the 2022 Model S Plaid) is full of ‘engineering magic’ that most people simply don’t realize.” There are several obvious improvements to the battery of the 2022 Model S Plaid, such as a reduced number of modules in the battery pack and an increased energy density, but it hasn’t really received attention.
2022 Model S Plaid is also the fastest mass-produced car in the world. Its acceleration from 0 to 60 miles (about 97 kilometers) is only 1.99 seconds, and its acceleration capacity of 100 kilometers is 2.1 seconds. Behind the improvement of
car performance is the result of Tesla's continuous challenges to new technologies.
1. Equipped with 18650 battery pack, but the battery energy density is higher
Last year, Tesla released the 2022 Model S/Model S Plaid. At that time, Musk shared the motor technology and three-motor system equipped in the new car, and only mentioned a small amount of battery information of the 2022 Model S Plaid.
However, a well-known foreign auto blogger believes that the battery pack of the redesigned 2022 Model S Plaid is more eye-catching than other improvements in the vehicle.
Regarding the reason why Tesla did not promote the performance of the 2022 Model S Plaid battery too much, foreign media speculated that it may be because the model did not use Tesla's latest 4680 battery or structural battery pack.
It is worth noting that the 2022 Model S Plaid does not even use Tesla's newer 2170 battery, which is available on many models of the Model 3 and Model Y.
and the 2022 Model S Plaid ended up using the 18650 battery packs of the previous generation Model S and Model X.
In this case, the reviewers studied the details of the 2022 Model S Plaid battery pack in depth, and found that although the battery pack of the new car uses a 18650 battery pack, its energy density is actually greater than that of the 2022 Model Y.

The volumes of the two batteries are different. The diameter of the 18650 battery is 18mm, the length of the battery is 65mm, and the diameter of the 2170 battery is 21mm, and the length of the battery has also increased to 70mm.
Generally speaking, since the 2170 battery is larger than the 18650 battery, the specific energy of the 2170 battery is greater than that of the 18650 battery, but the 2022 Model S Plaid uses a larger energy density than the previous 2170 battery, which can indicate that the new 18650 battery has been improved.
Previously, foreign media released two videos about Tesla's battery, which showed that Tesla seemed to reduce the number of modules in the updated battery pack from 16 to 5. This means that the battery pack in the 2022 Model S Plaid is lighter than the older Model S, but has a significantly higher energy density. Although the battery pack of
2022 Model S Plaid is small in size, it is very energy-intensive, which will cause consumers to worry about battery safety. Therefore, Tesla has invested a lot of work in ensuring battery safety.
Regarding the reasons for the increase in energy density, the reviewer believes that Tesla can make the energy density of its 18650 battery higher, in a manner that may be similar to that of Tesla's 2170 battery that has increased.
First, the reviewer said Tesla may have added more silicon to the battery structure, which is similar to the 4680 battery plan revealed by Musk at last year's Battery Day event.
Musk unveiled the 4680 battery on last year's battery day. The second reason is that Tesla uses the latest battery management system in the 2022 Model S Plaid, which is currently also used in the Model 3 and Model Y models.
Finally, the review video also shows Tesla's latest battery thermal management system, and the heating and cooling capabilities of the new system have been improved. This system is currently used in the new Model 3 and Model Y models.
In addition, the 2022 Model S Plaid is also equipped with a new and improved radiator and heat pump, which Musk also mentioned at the launch of the new car.
Tesla has greatly improved the battery performance of the 2022 Model S Plaid through three technologies: adding silicon elements, adopting a new battery management system and improving the thermal management system, and also reflects Tesla's technical strength in power batteries.
2. The fastest mass-produced car in history. The acceleration from 0 to 60 miles is only 1.99 seconds.
2022 Model S Plaid is the fastest mass-produced car in history. Although it is expensive, the domestic official website is 1.05999 million yuan, it is still much cheaper than the high-performance sports car of some other luxury brands and faster.

2022 Model S Plaid's acceleration time is 1.99 seconds. Foreign media believe that this car can be said to be a miracle of modern engineering, because it was almost impossible to complete before by pulling the acceleration time of 0 to 60 miles (about 97 kilometers) to less than 2 seconds, especially this car is still a large four-door sedan suitable for home use.
Although the 1.99-second data is obtained under the ideal test environment , and may not be able to reach this number in real life, as a full-size mass production car, the 2022 Model S Plaid has a 1.99-second acceleration capability of 0 to 60 miles (about 97 kilometers) in the test environment is still a commendable result.
Conclusion: Tesla car performance continues to improve
The continuous development of electrification process in the automotive industry, and the demand for power batteries is growing. As the leader of new energy vehicle companies, Tesla frequently makes new moves on batteries. It seems that Musk is determined to firmly grasp the initiative of batteries.
Tesla continues to adopt more advanced power battery technology. From this perspective, this car company has always adhered to the belief of being controlled by others but not being controlled by others. In the future, I believe Tesla will continue to launch higher-performance models.
