Tesla is a manufacturer that emphasizes 'cruising range' in order to provide the highest performance electric vehicles. Tesla has been working for many years to break the '400 mile' barrier.
The Model S Long Range Plus, announced in January 2020, said at the end of 2019, CEO Elon Musk said, 'It won't be long before the Model S reaches 400 miles.' It was said that 'I broke through the wall with a cruising distance of 400 miles', but the United States Environmental Protection Agency (EPA) measurement showed a result of '391 miles', and I was disappointed. have become.
For this result, mask CEO and 'for the examination of the EPA had to leave the key inside the vehicle while the door open, becomes a still contain the car's power supply, the battery is also lost 2 percent' mention . He claimed that he could officially achieve a cruising range of 400 miles without this EPA mistake.
Then, on June 15, 2020, Tesla announced that it has officially achieved a mileage of 400 miles by improving the 'Model S Long Range Plus'. The new 'Model S Long Range Plus' has a cruising range of 402 miles.
Tesla explains why the Model S Long Range Plus broke the 400-mile wall:
◆ Significant weight reduction
Some feedback from the design and manufacturing of Model 3 and Model Y was reflected in Model S and Model X. This opens up a new area of mass reduction while maintaining the vehicle's premium feel and performance. Furthermore, the standardization of seat manufacturing and the use of lightweight materials for the battery pack and drive unit have made it even lighter.
◆ 'Tempest' aero wheels and tires
The latest 8.5-inch wide aero wheel has reduced air resistance compared to the conventional model S long range wheel. Furthermore, by combining custom tires specially designed to reduce rolling resistance, we have succeeded in improving cruising range by 2%.
◆Improved efficiency of drive unit
In the drive unit mounted on the front of the vehicle body, the mechanical oil pump was replaced with a conductive oil pump to achieve optimum lubrication independent of vehicle body speed and reduce friction. By improving the permanent magnet type synchronous motor of the rear drive unit that is common to Model 3 and Model Y, we succeeded in further extending the cruising range during highway driving by 2%.
◆Maximizing regenerative braking
Tesla's latest drive function 'HOLD' combines the regenerative brake of the motor with the physical brake to smoothly stop the vehicle body. In order to achieve this smooth stop, regenerative braking can be executed at a slower speed and the deceleration force is further improved.
“Each improvement is relatively small, but we have succeeded in significantly improving efficiency, range and overall value by introducing these in combination with an active production line,” Tesla said. '.
