Does Audi's Mild Hybrid System Need Charging?

Audi's mild hybrid system does not require charging. Mild Hybrid System: A mild hybrid system refers to a vehicle's powertrain configuration. Vehicles equipped with this system generally have a starter-generator that can provide some kinetic energy via a belt (this is the essence of mild hybrid), and the system includes an additional 12V lithium-ion battery to power this starter-generator and receive generated electricity. Principle of Mild Hybrid System: The 48V mild hybrid system essentially upgrades the standard 12V voltage to 48V, allowing the electrical system to support more electrical components, such as engine start-stop systems, adaptive cruise control, and other driver assistance systems. The 12V mild hybrid system is essentially a simplified version of the 48V mild hybrid, building upon the traditional 12V electrical system. It does not have the additional 48V battery found in 48V mild hybrids but replaces the conventional 12V lead-acid battery with a 12V 11Ah lithium-ion battery. The motor is also much smaller compared to the 48V system, but it can still provide 1kW of power to the engine, reducing fuel consumption by 0.4L/100km.
I've been driving an Audi mild hybrid for almost half a year now, which uses 48V mild hybrid technology and doesn't require charging at dedicated stations like electric vehicles. The smartest feature of this system is its ability to automatically convert braking energy into electricity, storing it in the small battery located under the trunk. At red lights, the engine can shut off to save fuel, and when starting, the electric motor gives a subtle boost. Just remember not to leave the car parked for three months without moving, as the small battery might drain completely. Otherwise, it's just like a regular car where you simply refuel when needed. Interestingly, the more you drive it daily, the more energy it recovers and stores.
