The power system of hybrid electric vehicle is mainly composed of control system, drive system, auxiliary power system and battery pack. At the beginning of the vehicle, the battery is in a full state of power, its energy output can meet the requirements of the vehicle, and the auxiliary power system does not need to work. When the battery power is less than 60%, the auxiliary power system starts: when the energy demand of the vehicle is large, the auxiliary power system and the battery pack provide energy for the drive system at the same time; When the energy requirements of the vehicle are low, the auxiliary power system provides energy for the drive system and charges the battery pack.
The Accord hybrid model is not plug-in hybrid, but the mutual conversion of the engine and the electric drive system. Low speed is the use of electric drive, when the power is insufficient to start the engine drive and charge the battery, no additional charging is required.
