Embodiment 1
[0022] Embodiment 1: as Figure 1-Figure 5 As shown, an extended-range electric vehicle consists of electric steering system (EPS) 1, electric vacuum pump 2, vehicle instrument 3, other electrical accessories 4, 12V DC power supply 5, battery management system (BMS) 6, and power battery pack 7 , oil tank 8, DCDC 9, drive motor controller (MCU) 10, generator control unit (GCU) 11, radiator I 12, drive motor 13, final reducer 14, auxiliary power unit (APU) 15, compressor 16, Composed of radiator II 17 and vehicle controller (VCU) 18, an auxiliary power unit 15 is installed on the electric vehicle, the auxiliary power unit 15 is connected to the generator control device 11 and the vehicle controller 18, and the generator control device 11 is connected to the DCDC The conversion module 9 and the drive motor controller 10, the auxiliary power unit 15 adopts a generator set; the auxiliary power unit 15 is also connected to the power battery pack 7 through the on-board charging devic...
Embodiment 2
[0026] Embodiment 2: A drive control method for an extended-range electric vehicle. The method is as follows: the electric vehicle is charged by the power grid, and the electric energy is preferentially used for driving. When additional power supplement is required, the generator set of the auxiliary power unit is turned on for power supplement, and Make the engine work at the best working point, drive the generator to work, and the output mechanical energy is transmitted to the motor or power battery pack through the power converter. During the driving process, the vehicle controller analyzes the pedal opening signal, gear signal and key Switch the signal light to identify the driver's intention, turn off the low-voltage circuit, and the drive motor controller controls the power-on operation of the electric steering system; when the high-voltage circuit is powered on, the output of the drive motor is controlled by the drive motor controller. When the power of the power battery ...
