How does the Audi e-Tron capture and store regenerative braking energy?

I am interested in the technology behind the regenerative braking system in the Audi e-Tron. Can someone explain how it works and where the energy is stored?

The Audi e-Tron captures and stores regenerative braking energy through its two electric motors and the electrohydraulic brake system. The electric motors act as generators, converting the kinetic energy of braking into electricity, which is then used to charge the battery. The electrohydraulic brake system controls the amount of braking regeneration and ensures a smooth transition between regenerative and mechanical braking.

The energy from regenerative braking is primarily stored in the Audi e-Tron's lithium-ion battery pack. This high-voltage battery has a capacity of up to 95 kWh and is located beneath the passenger compartment, providing a low centre of gravity for improved handling. The battery also has a cooling system to maintain its optimal temperature.
