48V Mild Hybrid

The term "48V Mild Hybrid" refers to a type of vehicle hybrid system that utilizes a 48-volt electrical architecture alongside a conventional internal combustion engine. This system is categorized as "mild" because it cannot drive the vehicle solely on electric power; instead, the electric components assist the petrol or diesel engine to enhance efficiency and reduce emissions.A 48V mild hybrid typically incorporates a small electric motor/generator, a lithium-ion battery, and a power control unit. The electric motor can assist during acceleration, allowing the engine to run more efficiently, and can also enable features like regenerative braking, where energy is recovered during deceleration and stored in the battery.The 48V system offers several advantages, including improved fuel economy, decreased CO2 emissions, and enhanced performance compared to traditional gasoline or diesel engines alone. It is often seen as a transitional technology towards full hybrid or electric vehicles, making it an appealing choice for automakers looking to meet stricter emissions regulations without a complete shift to full hybrid or electric powertrains.
