For example, in the driving system of the energy-saving and electric-saving electric vehicle with the kinetic energy and the battery switching power supply described in the first paragraph of the patent application, the driving system may be provided with a rectifier, and a kinetic energy charging switch may be added inside the power feedback controller to make the power The output end of the generator is electrically connected to the battery via the kinetic energy charging switch, whereby the electric power feedback controller can make the driving motor available via the power switching switch during the non-high speed running of the electric vehicle Using the battery to supply electrical energy (battery power) During the power supply period), the electric vehicle is driven to drive (normal transmission), and the power feedback controller can also convert the kinetic energy of the driving motor, the transmission gear set and the power generator to the electric energy feedback via the kinetic energy charging switch ( AC power) by the rectifier, converts AC power into DC power (DC charging power), and supplements the power to the battery (kinetic energy charging), and further, when the electric vehicle is in high speed travel, the power feedback controller The driving motor, the transmission gear set and the kinetic energy of the power generator convert electric energy power feedback (kinetic energy generation), and the electric power switch can also be used to directly use the kinetic energy to supply electric energy (kinetic energy supply period) ) to continuously drive the electric vehicle to drive (auxiliary transmission); the microprocessor can also adjust the voltage at a timely and automatic state by detecting the voltage strength (the kinetic energy generation strength) rectified by the power generator via the transformer rectifier circuit Switching timing of the switch, when the power generator is detected to be rectified by the transformer rectifier circuit, the voltage is lower than When the voltage value of the microprocessor is set (the speed of the electric vehicle is lowered), the power feedback controller controls the power switch to be closed (closed circuit 1) to start a battery power supply circuit to be turned on, so that the drive motor can use the The power supplied by the battery, at the same time, the power feedback controller controls the kinetic energy charging switch to be closed (closed circuit 2) to activate a kinetic energy charging circuit to conduct, so that the driving motor, the transmission gear set and the kinetic energy of the power generator convert electrical energy The electric power feedback can also supplement the electric energy of the battery, or when the voltage of the power generator rectified by the transformer rectifier circuit is detected to be higher than the set voltage value (the electric vehicle speed increases), the electric power feedback control Operation Controlling the power switch to be closed (closed circuit 3) to activate a kinetic power supply circuit to enable the drive motor to directly use the kinetic energy to supply electrical energy, the battery also providing the electrical energy required for the operation of the microprocessor; And using the electric power feedback controller, the kinetic energy charging switch, the power generator, the transmission gear set and the auxiliary driving system formed by the rectifier, so that the driving motor can alternately use the battery or the kinetic energy during the traveling of the electric vehicle The power supply of power generation (alternating battery power and kinetic energy switching power supply), and can automatically supplement the battery's electric energy (automatic kinetic energy charging), so that the battery can be powered by more energy-saving, more battery life power Electric vehicles are used for travel.
