What is the difference between 48V mild hybrid and plug-in hybrid?

[McAna]

48V mild hybrid and plug-in hybrid differ in the following ways: 1. Different working principles: The 48V mild hybrid system consists of a 48V lithium-ion battery pack and an integrated starter/generator. The battery pack is installed at the rear of the vehicle or under the rear seat, and the mild hybrid starter generator replaces the traditional alternator and starter motor. Plug-in hybrid, as the name suggests, is a hybrid vehicle that requires plugging in a charger to charge. This type of vehicle is equipped with a conventional internal combustion engine, a small electric motor, and a battery pack, with the battery directly connected to the electric motor. 2. The 48V mild hybrid is more efficient but costly. The 48V electrical system provides many new technologies for vehicles, which is a future development trend. Compared to PHEV (plug-in hybrid electric vehicles), it is more efficient and can create more possibilities. However, the downside is that the integrated generator and starter motor result in higher repair costs if damaged, and the failure rate is also higher than that of conventional vehicles.
