Mild hybrid vehicles do not require additional charging, as their 48V mild hybrid system achieves energy self-sufficiency through brake energy recovery and coordinated operation with the engine. The BSG motor in these models recovers kinetic energy during braking and stores it in the battery, then assists the engine in power output while driving, reducing combined fuel consumption by approximately 10%-15% while improving power responsiveness. Unlike plug-in hybrid models, mild hybrid systems employ a dual-voltage circuit design (12V and 48V) and sustain operation through internal energy circulation, eliminating dependence on external charging infrastructure or alterations to conventional fuel vehicle usage patterns. The technological core resides in the efficient coordination between lithium-ion batteries and power conversion units, enabling features like automatic engine shutdown during idling, electric boost during acceleration, and continuous operation of electrical components such as air conditioning systems. This technology effectively balances ecological considerations with the practicality of traditional combustion-engine vehicles, making it a prevalent feature in regional market offerings like the Proton X50.
