What is the Difference Between 48V Mild Hybrid and Full Hybrid?
1 Answers
Mild hybrid and full hybrid vehicles differ in their working principles, resulting in varying fuel consumption. Below are their specific differences: 1. 48V Mild Hybrid: Also known as MHEV, the most common 48V mild hybrid system quadruples the standard 12V voltage to easily power higher-capacity onboard electrical equipment. This allows high-power components like the power steering, starter motor, and air conditioning to remain operational even when the engine is off. The 48V system also better optimizes engine start-stop, braking, and acceleration, directly impacting fuel efficiency and emissions. However, strictly speaking, the 48V mild hybrid system isn't a true hybrid but rather an electrification upgrade for conventional fuel vehicles. 2. Full Hybrid: This system adds one or more electric motors to the internal combustion engine, not only assisting the engine to deliver stronger power but also enabling pure electric driving under low-speed or steady-state conditions. Particularly in congested urban environments, full hybrids demonstrate significant fuel-saving advantages. However, they come with higher upfront costs - hybrid versions typically cost 20,000-30,000 RMB more than their gasoline counterparts for the same model. When calculated, this additional purchase cost roughly equals the long-term fuel savings compared to conventional vehicles.
