How many kilowatt-hours does it take to charge an electric car once?

Electric vehicles require different amounts of electricity to charge depending on the specific model. In fact, to determine how much electricity is needed for a full charge, you simply need to look at the battery capacity. Battery capacity is measured in KWH (kilowatt-hours), where 1 KWH equals 1 kilowatt-hour of electricity. Therefore, the number of KWH the battery has represents how much electricity it can output, and conversely, how much is needed to fully charge it. Additional Information: 1. In reality, electric vehicle batteries are not allowed to be completely discharged, so charging will not be at full capacity. Typically, an electric vehicle battery is around 10Ah, with a voltage of 48V (some are 36V). The charging voltage is slightly higher, around 60V, resulting in 600Wh. This means a full charge requires 0.6 kilowatt-hours of electricity. 2. Taking the Tesla Model-3 pure electric vehicle as an example, the 2019 Long Range All-Wheel Drive Model-3 has a battery capacity of 75kWh (kilowatt-hours), while the 2019 Standard Range Rear-Wheel Drive version has a battery capacity of 60kWh. Since each kilowatt-hour equals 1 kilowatt-hour of electricity, the Long Range All-Wheel Drive Model-3 requires 75 kilowatt-hours to charge from 0 to full, and the Standard Range Rear-Wheel Drive Model-3 requires 60 kilowatt-hours.
