At present, in order to meet the increasingly stringent environmental protection requirements and the continuously improved hundred kilometers of fuel consumption targets, under the situation that the thermal efficiency of the existing internal combustion engine is difficult to realize the span-type lifting of the brake elbows, more and more small cars selectively build a 48V light hybrid platform and cooperate with the starting and stopping functions of the engine, so that the effects of saving energy and reducing consumption are achieved.

The vehicle-mounted air conditioner compressor of the traditional fuel vehicle is driven by an automobile engine, and if the refrigeration function of an air conditioner is required to be continuously used in a static state (such as a parking state and an engine start-stop working state) of the vehicle, the engine is required to be in an idle running working state, which inevitably causes extra oil consumption and tail gas emission; meanwhile, the experience feeling and the comfort degree are also influenced by the waste gas and the noise generated by the automobile engine.

The traditional exhaust gas turbocharger can greatly improve the output power of an engine on the premise of not increasing the basic displacement of the engine, but always has the problem of delaying turbine intervention (influenced by the flow speed of exhaust gas). At present, most of turbocharging requires that the rotating speed of an engine reaches more than 1500 revolutions to be effectively output, and if daily driving is mainly carried out on congested road sections in urban areas, turbocharging basically cannot play an expected role in a stop-and-go state. The whole vehicle has slow acceleration response, poor linearity and poor driving experience at low rotating speed.
