What does HEV hybrid mode mean?

[Giselle]

HEV mode is the hybrid power mode of the vehicle, and also represents hybrid electric vehicles. Hybrid electric vehicles are powered by a combination of a traditional fuel engine and an electric motor. The following is relevant information about HEV mode: 1. Development background: The electric motor is combined with an auxiliary power unit in a vehicle to provide driving force. The auxiliary power unit is actually a small fuel engine or power generation unit. 2. Hybrid methods: After more than a decade of development, the hybrid power system assembly has evolved from the original discrete structure of the engine and motor to an integrated structure of the engine, motor, and transmission, known as the integrated hybrid power assembly system. Hybrid power assemblies can be classified by power transmission routes into three types: series, parallel, and series-parallel.
