Model 3 Standard Range
Tesla hasn't
started making the Standard Range version yet. Therefore I want to explain how I calculated the range numbers even though this car doesn't exist yet. The calculation is based on cell counts. We know that the Long Range pack has 4416 cells and the standard range has 2976 cells (source). The Model 3 LR's EPA highway dyno test score is 454.7 mi (source: page 7). Using the cell count ratio, the Model 3 SR's score should be (2976/4416) * 454.7 mi= 306.4 mi with 18" wheels and no Aero covers.
However, that would be the range if the weight of the car remained the same as the Model 3 LR but the smaller battery is lighter. Luckily we know the weight numbers for these cars from Tesla's page here: 3549 lbs. for the Model 3 SR and 4072 lbs. for the Model 3 LR. Using these numbers, I calculated that the SR's EPA highway dyno score should be 320.2 mi. Using that number, I calculated the range numbers for the SR too.
By the way, in case people are curious about the battery size, we know that the Long Range pack has 78,270 Wh (78.27 kWh) usable capacity (source: page 6 footer). Therefore the Standard Range pack is expected to have (2976/4416)*78270= 52,747 Wh usable capacity.
Model 3 Mid Range
The Standard Range battery has 96*31= 2976 cells and the Long Range battery has 96*46= 4416 cells. 96 comes from 96 bricks. Each brick consists of cells connected in parallel. See the leaked information here. The 2170 cells are 3.7 Volts. Therefore each brick is also 3.7 Volts. Then the bricks are connected in series which provides 96*3.7= 355.2 Volts which is the pack voltage. In other words, the MR battery will have 96 bricks just like the LR and SR batteries to achieve 355.2 Volts. In addition, Elon said that the MR battery has just fewer cells but otherwise uses the same pack as the LR battery.
Because LR has 46 cells per brick and SR has 31, the middle would be 38.5 cells. I have done some calculations considering both 38 cells or 39 cells per brick options. Based on the vehicle
weight number Tesla released for the
Mid Range version, 39 looked more likely but considering the 260 mi EPA rating, the numbers look more balanced if we assume 38. Also, for official purposes, Tesla rates the pack sizes at 75,
62 and 50 kWh. Because they went with 62 instead of 63, 38 instead of 39 makes more sense. So I went with 96*38= 3648 cells and calculated range numbers based on that.
