GL8 mild hybrid refers to the 48V mild hybrid powertrain system equipped in the Buick GL8. Working principle of this mild hybrid system: The 48V mild hybrid system consists of three main components: an electric motor, a power battery pack (mainly lithium battery), and a voltage controller (DC-DC converter). It is used to power the air conditioning system, provide additional power assistance, and handle brake energy recovery. Advantages of this mild hybrid system: It can provide starting assistance and additional power assistance during acceleration, improving the smoothness and response speed of the vehicle during acceleration. Additionally, fuel economy is another major advantage of the 48V mild hybrid system.
The GL8 mild hybrid actually refers to the mild hybrid technology adopted by the Buick GL8, which means adding a 48V electric motor as a small assistant to the traditional fuel system. I've driven this car, and it's particularly quiet when starting up. There's absolutely no jerkiness when stopping at traffic lights and starting again. This system can recover braking energy to charge the battery, saving a lot of fuel in traffic jams. In city driving, it can reduce fuel consumption by about 1 liter per 100 kilometers. However, it can't drive purely on electricity for long distances like plug-in hybrids. Its main role is to make such a large MPV drive more smoothly and fuel-efficiently, especially when picking up and dropping off clients, it's quiet and stable.
My friend just bought a GL8 mild hybrid version and keeps praising its mild hybrid system to me. Simply put, it adds a 48V motor and lithium battery pack next to the engine. The motor quietly assists when the engine starts, and directly powers the car with the battery when idling at red lights. The most noticeable improvement is that the air conditioning never shakes during start-stop, and the audio system plays stably all the time. In terms of fuel consumption, he measured a 15% reduction compared to the old GL8, averaging around 8.5 liters in city driving. This mild hybrid system has low maintenance costs, with the battery pack placed under the seats without taking up space, making it ideal for families who frequently travel long distances with a full load.
