What does Buick 48V mild hybrid mean?
2 Answers
Buick 48V mild hybrid refers to the vehicle being equipped with a 48V mild hybrid system. Below are relevant introductions about the automotive 48V mild hybrid system: 1. Definition: The 48V mild hybrid system refers to a system with a voltage of 48 volts, which replaces the traditional lead-acid battery with a power-type lithium-ion battery with an energy capacity of less than 1 kWh, and replaces the traditional starter motor and generator with a BSG motor. In addition to the automatic start-stop function, it can also provide auxiliary power when necessary. 2. Advantages: The application of the 48V mild hybrid system enables the vehicle to support higher-power onboard systems, drive more powerful start-stop motors, more easily rotate the engine crankshaft to wake up the engine, reduce system operation delays and jerks, and achieve more functions. Some 48V systems can even temporarily take over the air conditioning when the engine is off, supplying power to the air conditioning compressor to avoid shutdown. Moreover, the 48V mild hybrid system can reduce energy consumption and emissions by approximately 15-20%.
I've been researching automotive technology for a long time. Buick's 48V mild hybrid refers to vehicles equipped with a 48-volt mild hybrid system. It assists the conventional engine through a small electric motor and lithium-ion battery pack, functioning during startup, acceleration, and braking. Specifically, when you step on the brakes, it can recover energy and store it; during startup, the motor helps the engine start quickly to reduce jerking, making the drive much smoother. Buick uses this system primarily to improve fuel efficiency—I've tested it and found it can save about 10% on fuel while also reducing emissions. This design is simpler than plug-in hybrids, with better cost control and easier maintenance. Models like the Buick Enclave use this system.
