How does the electric drivetrain in the BMW i7 work?

I am interested in the technology behind the BMW i7's electric drivetrain. How does it differ from traditional gasoline engines and what are its main components?

The electric drivetrain in the BMW i7 differs from a traditional gasoline engine in many ways. While a gasoline engine combusts fuel to generate power, an electric drivetrain uses electricity to power the motor. The main components of an electric drivetrain include the battery, motor, and power electronics. The battery stores the electricity needed to power the motor, while the power electronics control the flow of electricity from the battery to the motor. The motor then converts the electrical energy into mechanical energy to power the vehicle.

One major advantage of the electric drivetrain in the BMW i7 is its efficiency. Unlike gasoline engines, electric motors can convert almost all of the energy from the battery into motion, resulting in a more efficient use of energy. Additionally, the electric drivetrain produces zero emissions, making it more environmentally friendly.
