83 Vehicle Architectures and Design FIGURE 3.28 Tesla Model 3 battery SoC simulation for one UDDS cycle. iii. The battery capacity of the Tesla battery is 75 kWh and the battery voltage is 375 V. The simulation is started with the battery at full charge (100% SoC). As seen from Figure 3.28, the SoC drops 2.3% from 100% to 97.7% during the UDDS drive cycle. This corresponds to an energy consumption of 1.73 kWh. The distance traveled during the UDDS cycle is 7.49 miles. Therefore, the distance that can be traveled in one full charge of the battery can be calculated as follows:
100 Range = Ч Distance ∆ UDDS SoC UDDS On substituting, we get 100 Range = Ч 7.49 = 325 mi 2.3 This calculation neglects mechanical losses in the motor and transmission and losses in the inverter.
