What is the function of a 48V mild hybrid system?
1 Answers
48V mild hybrid systems can help reduce fuel consumption, enhance power, and decrease emissions. Below is a detailed introduction to the 48V mild hybrid system: 1. System division: Volvo's 48V mild hybrid system builds upon the 12V battery by adding a 48V lithium-ion battery hybrid system. Here, the 12V circuit handles traditional electrical loads such as lighting, ignition, and audio systems. The 48V circuit supports active chassis systems, air conditioning compressors, and regenerative braking systems. 2. Structural composition: The 48V mild hybrid system mainly consists of three core components: the boost recovery motor, power conversion unit, and power battery. In this system, the electric motor hardly participates in directly driving the vehicle but serves as a tool for energy recovery to assist the engine. This allows all electrical devices in the vehicle to minimize reliance on the engine, enabling the engine to drive the vehicle more efficiently.
