How does the Audi A7's 48V mild hybrid system work?

I've read that the Audi A7 has a 48-volt mild hybrid system. Can someone explain how this system works and how it differs from a traditional hybrid system?

The 48-volt mild hybrid system in the Audi A7 uses a small lithium-ion battery and a belt alternator starter to assist the engine. It can also recover energy during braking to recharge the battery. This system works similarly to a traditional hybrid, but on a smaller scale.

The Audi A7's 48-volt mild hybrid system is designed to reduce fuel consumption and emissions while providing a smoother driving experience. The system can turn off the engine when coasting or coming to a stop, and seamlessly restart it when needed. It also allows for improved start-stop functionality.

The 48-volt mild hybrid system in the Audi A7 is a smart and efficient way to enhance the car's performance and efficiency. By utilizing regenerative braking and engine coasting, it helps save fuel and reduce emissions. Plus, the seamless start-stop function adds to the overall driving experience.
