phevTechnical routeAs a technology that looks perfect on paper, it faces a dilemma in practical applications. Among them, the biggest problem is how to balance the contradiction between mandatory power retention and power consumption. Mandatory power retention can be increasedPower batterybut will limit the upper limit of NVH control and energy consumption control. Running out of power can provide a driving experience close to that of a pure electric vehicle, but it will affectPower batteryas well as performance output in extreme cases. In addition to these specific scenario questions,phevTechnology also faces contradictions in terms of internal combustion engine power generation, kinetic energy** and energy output. Among them, internal combustion engine power generation and energy ** are classified as "energy supplement" projects, andphevThe P2 front axle single-motor structure is often chosen, which can be guaranteedPower batteryLife and risk in extreme scenarios are low, but the power output and power** efficiency of the front axle motor are affected. Another coupling is the P1 and P3 architectures, which can improve the efficiency of direct fuel drive by adding gears to the internal combustion engine section, but there are cost and technical requirements to consider.
Currently mainstreamphevThe solution to the problem can be summarized as "treating headaches and sore feet". In the electrification segment, the easiest way to do this is to increaseBatterycapacity, which relieves the pressure on energy output and **, but reduces efficiency and increases costs. In addition,phevIt is also possible to increase the gear position in the internal combustion engine to improve the efficiency of direct fuel drive. These methods are carried out within the framework of existing technology and have not broken through the bottleneck.
