What is the Audi A6L 48V Mild Hybrid?

[McRhett]

Here is a detailed explanation of the 48V mild hybrid system: 1. 48V Mild Hybrid System: The "48V Mild Hybrid" is also known as MHEV (Mild Hybrid Electric Vehicle). It upgrades the traditional 12V circuit voltage to 48V and replaces the conventional starter and alternator with a BSG (Belt-Driven Starter Generator) and a 48V/12V bidirectional DC/DC converter. 2. Basic Principle of the 48V Mild Hybrid System: In terms of mechanical definition, the 48V mild hybrid system is not classified as a new energy vehicle because it cannot independently provide electric power for pure electric driving. During daily use, the electric energy is only used to assist in vehicle propulsion. Building upon the original 12V electrical system of conventional vehicles, the voltage is increased to 48V, and components such as electric motors and battery packs are added to enable auxiliary vehicle propulsion and energy storage/recovery functions.
