What is the Audi A6L 48V Mild Hybrid?

[DeStephanie]

Here is a detailed explanation of the 48V mild hybrid system: The "48V mild hybrid," abbreviated as MHEV, involves upgrading the traditional 12V circuit voltage to 48V and replacing the conventional starter and alternator with a BSG (Belt-Driven Starter Generator) and a 48V/12V bidirectional DC/DC converter. Basic principles of the 48V mild hybrid system: At the mechanical definition level, the 48V mild hybrid system is not classified as a new energy vehicle because it cannot independently provide electric power for pure electric driving. In daily use, the electrical energy is only used to assist in vehicle propulsion. On the basis of the traditional 12V electrical system, the voltage is increased to 48V, and with the addition of components such as an electric motor and battery pack, it achieves the effects of assisting vehicle propulsion and storing/recovering electrical energy.
