What does the 48V mild hybrid system mean? Is it considered new energy?

[CharlieLee]

48V mild hybrid system is not classified as new energy from a mechanical definition perspective. Below 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 48V Mild Hybrid System The 48V mild hybrid system is not categorized as a new energy vehicle in mechanical terms because it cannot independently provide electrical energy for pure electric driving. In daily use, electrical energy is only used to assist vehicle propulsion. Based on 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 functions like assisting vehicle propulsion and storing/recovering electrical energy.
