How does the energy allocation system work in an Audi A2?

I've been reading about the advanced energy usage system in the Audi A2, but I still can't wrap my head around it. Can someone explain how it actually operates and how it contributes to the car's overall efficiency?

The energy allocation system in the Audi A2 is controlled by the car's central computer, which monitors and adjusts the power distribution between the engine, battery, and electrical components based on various factors such as driving style and battery charge. This allows for optimal energy usage and contributes to the car's impressive efficiency.
