Embodiment Construction

[0012] A mileage booster control system for an electric vehicle, comprising a mileage booster 10, the mileage booster 10 is connected in parallel between a high-voltage battery 20 and an inverter 30 in the form of a common bus, and the high-voltage battery 20 is connected to a vehicle controller 50, The input terminal of the vehicle controller 50 is connected to the EV / PHEV switch for detecting the request of the driving pure electric power generation mode or the hybrid power generation mode, wherein the EV switch refers to the pure electric power generation mode, and the PHEV switch refers to the hybrid power generation mode. The inverter 30 is connected with the driving motor 40, and the torque of the driving motor 40 is transmitted to the driving wheels through the gearbox to drive the whole vehicle to run. The vehicle controller 50 controls the mileage booster 10 to generate electricity and supply power to the high-voltage battery 20, such as figure 1 shown.

Abstract

The invention relates to a control system of a mileage increaser of an electric vehicle, which comprises the mileage increaser, wherein the mileage increaser is parallel-connected between a high-voltage battery and an inverter by the way of a common bus, the high-voltage battery is connected with a whole vehicle controller, an input end of the whole vehicle controller is used for detecting an EV/PHEV switch required by the pure electric power generation mode or the hybrid power generation mode of driving, the inverter is connected with a drive motor, and the whole vehicle controller starts the mileage increaser for supplying power to the high-voltage battery. The invention further discloses a control method of the control system of the mileage increaser of the electric vehicle. The whole vehicle controller calculates the basic power generation requirement according to the electric quantity state of the high-voltage battery, and controls a power generator to output the corresponding power generation power according to the different modes. The control system can realize the power generation function of the mileage increaser to the whole vehicle, prolong the range of the vehicle and further effectively control the emission, the oil consumption and the NVH performance.

Description

technical field [0001] The invention relates to the control field of electric vehicles, in particular to a control system and a control method for a mileage increaser of an electric vehicle. Background technique [0002] Energy crisis and environmental deterioration have become important factors restricting global development. Research on energy-saving and environmentally friendly vehicles is one of the effective means to alleviate energy pressure and reduce environmental pollution. Electric vehicles are driven by pure electricity, which can reduce emissions and reduce energy consumption. Compared with traditional internal combustion locomotives or hybrid vehicles, the typical differences of pure electric vehicles (EV) are: 1. The electric motor is the driving power source of the vehicle. It can realize the forward and reverse of the vehicle; 2. The motor can participate in the braking of the vehicle and recover the braking energy; 3. The main energy of the electric vehicle ...
