When now Popular Tesla Model S electric car It was first launched in 2012 and there was no supercharger available at the time.Today, there are 25,000 Tesla Superchargers around the world, and Model S Plaid Adopt a new power system, Tesla was able to redesign the battery to take advantage of the third-generation 250-kilowatt supercharger. Although Tesla is still using 18650-shaped cylindrical battery cells, they have now improved their chemical composition to provide higher performance and durability. (This is the fourth major chemical improvement since the first Model S.) With the latest 100 kWh battery pack, Tesla claims that Plaid can restore 187 miles of driving range within 15 minutes of charging the V3 supercharger. But how realistic is this statement in practice?
First introduce the background Generally charge electric vehiclesThere are many factors that determine the charging performance, from ambient temperature to battery temperature, from charging state to charging station type. Therefore, the charging rate does vary in practice. Lithium-ion batteries have a certain operating temperature range, usually 40-130 degrees Fahrenheit, and the higher end of this range is usually good for fast charging. For electric vehicles that are unplugged or unplugged in cold weather, the charging time will be extended. In Tesla, when the driver puts the super charging station as a destination into the navigation, the car will be prepared for fast charging before the battery pack reaches the plug. This helps provide a more consistent fast charging experience and eases congestion at charging sites.
In our test, using a pre-processed battery pack and an ambient temperature of 71 degrees, the Tesla Model S Plaid took 51 minutes to charge from 5% to 95%, an increase of 87 kWh. The latter figure indicates that the available battery capacity is approximately 97 kWh, of which 3 kWh is used as a buffer. As shown by the charging curve, it did reach the maximum V3 supercharger rate of 250 kW and maintained that number within five minutes of charging from 10% to 30%.
In order to take advantage of the peak charging rate, the best starting point is to show it to the Supercharger when the Model S Plaid is depleted to 0% to 5%. After the peak, as the state of charge of the battery pack increases, the charging rate gradually decreases. (Imagine people rushing into the elevator: it’s easy when the elevator is empty, but as more people enter, the longer it takes them to find space to swing.) If you are traveling on a road, 60% is good to stop charging the car Continue driving until you reach the next super charging station. The reason is that after 60%, the charging rate starts to drop below 2 kWh per minute, so you might as well go to the next charging station, at least from a pure time perspective. Hey, 18 minutes of charging time is great for going to the toilet again.
As for Tesla’s claim to increase the range of 187 miles within 15 minutes of charging time, this is very accurate for Model S Plaid. (At least use standard 19-inch Tempest wheels.) However, this happens only when you start charging the car and there is very little battery remaining. On the Model S Plaid with more energy-intensive optional 21-inch wheels, you want to add 167 miles of range in 15 minutes.

Scope: Real-world estimates of Dragstrip vs. EPA vs. MotorTrend
Manufacturers like to talk about the range of their electric cars in order to sell them to people when buying electric cars, but in reality, the range depends largely on your driving style, traffic conditions, and weather conditions. The Model S Plaid with 21-inch wheels uses 2.5% of the battery to complete a quarter-mile run on the track, so theoretically-we didn’t actually start it repeatedly until the battery runs out-it has about 10 miles If used for 40 consecutive traction belt runs. Tesla said that the Model S Plaid equipped with 21s has an EPA estimated cruising range of 348 miles, which is a mixture of 55% highway and 45% urban driving based on EPA conditions. Do you see the difference in the scope of different use cases?
We use Tesla Model S Plaid for highways (70-75 mph) and different road routes for city driving, and then look for efficiency. We drove four times on each route, turned on the air conditioner twice and set it to 72 degrees, and turned off twice and turned on only the fan.
When the average ambient temperature is below 75 degrees, we see 3.43 mph for urban driving and 3.14 mph for highway. Using the same EPA highway to city ratio, our theoretical measurement range is 318 miles.
By multiplying the number by the energy, you can display the estimated range. For example, on a road trip, you may be driving mainly on highways or highways, so the total cruising range you see is 305 miles. However, in real life, you will most likely not drive from a fully charged battery pack to an empty battery. Suppose you charge 72 kWh (from 5% to 80%): Expect to drive about 226 miles on the highway at 70-75 mph.
