Referring to fig. 5, the charging circuit of the present invention uses a conventional charging circuit, the circuit charges the battery after transformation, bridge rectification and conditioning, and a switch S1 is disposed in the circuit.

In order not to influence the comfort of the whole vehicle and to fully utilize the bumping kinetic energy of the vehicle, the resistance of the exciting circuit is changed through a gear switch S2 arranged on a power supply loop, so that the size of the exciting current is changed, namely: when the vehicle is in full load, the gear switch is in the second gear, the exciting current is large, and the generating capacity of the motor is improved; when the vehicle is in no-load, the gear switch is in first gear, and exciting current is small, so that the comfort of the whole vehicle is not influenced.

The specific principle is as follows:

1. when the generator does not generate power or the rotating speed is low, the switch S1 is disconnected at the moment, the excitation loop is not connected, and the generator does not work;

2. when the rotating speed reaches a certain critical rotating speed, the ECU control circuit is switched on, namely the switch S1 is closed, and when the generated voltage is less than the voltage of the storage battery, the storage battery supplies power for the excitation winding; along with the increase of the rotating speed of the rotor, when the voltage of the generator is increased to be greater than the voltage of the storage battery, the generator generates electricity by self excitation, charges the storage battery and supplies power to an electric appliance; the output voltage UB of the generator is less than the upper limit UB2 regulated by the regulator, the transistor VT1 is continuously cut off, the transistor VT2 is continuously conducted, but the current of the magnetic field is supplied by the generator at the moment, and the voltage of the generator rapidly rises along with the rise of the rotating speed; 3. when the generator voltage rises to equal the upper regulation limit UB2 (battery full), the regulator regulation of the voltage begins. At the moment, the voltage stabilizing diode VS is conducted, the transistor VT1 is conducted, the transistor VT2 is cut off, the magnetic field circuit of the generator is cut off, and the magnetic flux is reduced because the magnetic field is cut off, so that the output voltage of the generator is reduced; 4. when the voltage of the generator drops to be equal to the lower regulation limit UB1, the voltage stabilizing diode VS is cut off, the transistor VT1 is cut off, the transistor VT2 is conducted again, the magnetic field circuit is conducted again, and the voltage of the generator rises; and repeatedly, the output voltage UB of the generator is controlled within a certain range, and the rectification function is achieved.

When the vehicle is unloaded, the manual switch button on the instrument desk enables the gear switch S2 to be in the first gear position, the loop passes through the resistor R4, and the exciting current is small.

When the vehicle is fully loaded, the manual switch button on the instrument desk is passed to make the gear switch S2 be in the second gear position, so that the loop does not pass through the resistor R4, and the exciting current is larger.

Referring to fig. 6, in order to adapt to more types of automobiles, a boost circuit and a DC-DC converter are provided in a charging circuit of an electric automobile, wherein a DC-DC converter is used to convert a DC voltage or current into a high-frequency square wave voltage or current, and then the high-frequency square wave voltage or current is rectified and smoothed into a DC voltage for output; the booster circuit boosts the voltage and then supplies power to the battery.
