How does the Audi e-Tron synchronize the power output of its dual motors?

I read that the Audi e-Tron has a dual motor setup. How does this work exactly and how is the power output synchronized between the two motors?

The Audi e-Tron's dual motor setup consists of one motor at the front and one at the rear, giving the car all-wheel drive capabilities. The motors are connected via a power electronics unit, which communicates with the vehicle's electronic control unit to synchronize the power output between the two motors.

In normal driving conditions, the e-Tron primarily uses its rear motor for propulsion, but when additional power or traction is needed, the front motor kicks in to assist. The power distribution between the two motors is constantly monitored and adjusted, ensuring optimal performance and efficiency.

The dual motor setup also allows for regenerative braking, as energy can be recaptured from both motors. This helps to increase the overall range of the e-Tron and also reduces wear and tear on the brakes.
