What does 48V mild hybrid mean?

[StLola]

48V mild hybrid refers to a vehicle equipped with a 48V mild hybrid system. "48V mild hybrid" is also known as MHEV, which 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 bidirectional 48V/12V DC/DC converter. Below is a detailed explanation of the 48V mild hybrid system: Definition of the 48V mild hybrid system: "48V mild hybrid" is also known as MHEV, which 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 bidirectional 48V/12V DC/DC converter. Basic principles of the 48V mild hybrid system: The 48V mild hybrid system is not classified as a new energy vehicle at the mechanical definition level because it cannot independently provide electrical energy for pure electric driving. In daily use, electrical energy is only used to assist vehicle propulsion. On the basis of the traditional vehicle's 12V electrical system, the voltage is increased to 48V, and with the addition of components such as electric motors and battery packs, it achieves the effects of assisting vehicle propulsion and storing/recovering electrical energy.
