Examples
The range-extending control system for the vehicle comprises an engine 1, wherein the engine 1 is connected with an ECU2, the ECU2 is in signal connection with a range-extending controller 3, the range-extending controller 3 is in signal connection with a motor controller 4 and a BMS5, the motor controller 4 is in high-voltage connection with a driving motor 9 and a battery pack 6, the battery pack 6 is connected with a BMS5 and a rectifier 7, the rectifier 7 is in high-voltage connection with a generator 8, and the generator 8 is mechanically connected with the engine 1;
the range-extending controller 3 calculates the required power of the generator according to the current opening degree of the accelerator pedal, the SOC of the battery pack 6, the allowable charging and discharging current of the battery and other information, then converts the required power of the generator 8 into the required rotating speed information and the compensation torque information and sends the required rotating speed information and the compensation torque information to the ECU2, the ECU2 changes the rotating speed of the input side of the generator 8 by changing the rotating speed of the engine 1, the voltage of the output side of the generator 8 is in direct proportion to the rotating speed of the input side, therefore, the voltage value of the output side of the generator 8 is changed after the input rotating speed of the generator 8 is changed, the load bearing capacity of the generator 8 is improved after the voltage value of the output side of the generator 8 is increased, and therefore the output power of the generator 8 can;
when the vehicle is accelerated: after receiving the power demand information of the driving motor 9, the range-extending controller 3 controls the engine 1 to increase the rotating speed and change the real-time current of the high-voltage battery by combining the current SOC (SOC is more than or equal to 90 percent) of the battery pack 6 (the rotating speed of the engine 1 is reduced to the idle rotating speed) through the ECU2 so as to match the power of the generator 8 with the charging power and the driving power of the battery pack 6 in real time, and the target output power of the generator 8 is the sum of the driving powers of the charging power meters of the battery pack 6. And the real-time matching between the power of the generator 8 and the charging power and the driving power of the battery pack 6 is divided into three sections: the vehicle runs at 0-30km/h, the range-extending controller 3 sends information to the ECU2, the ECU2 controls the target rotating speed 2000rpm of the engine 1, the range-extending controller 3 calculates the power generated according to the MCU discharge to adjust the output electric quantity of the APU, the power generated is adjusted according to the actual power, and the power generated is more than or equal to 10 KW;
