Tesla Model 3 long-range design explained in EPA filing Engadget

Elon Musk once said that Tesla couldn't fit a 100kWh battery into the Model 3, but he didn't specify what kind of battery the car will have. Now, a bunch of EPA certification documents have finally revealed that the long-range version of the all-electric sedan is equipped with a 350-volt, 230-amp-hour battery pack. If you compute for the battery's kilowatt-hour value using those numbers, you'll get 80.5kWh of max capacity. That's what gives the long-range Model 3 variant the power to travel 310 miles between charges, only 5 miles shorter than the 315-mile range of the Model S and X. Tesla upgraded those vehicles' batteries to 100kWh in late 2016.
