How does the i7's electric engine work?

I am interested in the technical aspects of the BMW i7 and I would like to know how its electric engine works. Can you explain the process in detail?

The BMW i7's electric engine relies on lithium-ion batteries that power an electric motor. When you press down on the accelerator, the motor uses electrical energy from the batteries to rotate its rotor, generating torque and propelling the car forward. Regenerative braking is also used to recapture energy that would otherwise be lost when braking, allowing for a longer driving range.

The i7's electric engine is designed to work in combination with a traditional gasoline engine. When driving at lower speeds, the electric motor will power the car, providing a smoother and more efficient ride. As you increase your speed, the gasoline engine will kick in to provide additional power. This allows for a seamless transition between electric and gas power and also helps extend the car's overall driving range.

In addition to being environmentally friendly, the i7's electric engine also contributes to a better driving experience. The instant torque provided by the motor results in quicker acceleration and a smooth, quiet ride. You also don't have to worry about shifting gears, making for a more relaxed and enjoyable driving experience.
