In addition, the DC/DC transformer-sub-measuring coil power supply portion needs to be controlled by another set of "_ic output control circuit" for controlling the FET. The switching action is to perform the alternating and variable voltage function of the ·c high-frequency transformer, and it is impossible to directly act on the FET trigger surface by the central arithmetic unit, and the DC/DC high-frequency riser is changed and changed. Pressure and various charging state control purposes. In addition, for example, China Lai's May 21st, Announcement No. 588881, "Electric Assisting Charger F, Controlling Qian Liang" is based on the basic circuit of the electric squadron's scales - charging controller and charging driver, and with the general The rectifier performs charging operations. The structure charging switch is directly connected to the battery pack, and the microprocessor in the electric walker determines whether the charging is turned on or not. When an external power flow is detected, the motor switch is turned off synchronously. A typical "specifically rectified voltage" rectifier is commercially available in the architecture for charging. The so-called commercially available general "specifically-specific voltage" rectifiers should generally be used as an external power supply after the AC mains is transformed into a specific voltage value via a low-frequency transformer (mains approximately 6 Hz), and then the power is supplied. The so-called "charge controller" in the text forms a rectified (AC to DC) voltage V. The commercially available rectifiers with a specific rectified voltage are not only bulky, heavy, but also have poor power conversion efficiency. And a commercially available general-purpose "specific rectified voltage" rectifier with a microprocessor, although it can replace the special-purpose charger, but still need to be independently externally stored in use, in the operation and device and the current independent external dedicated charging Root 200841554 This difference is not big. And when the battery is charged with a commercially available general rectifier, the voltage is fixed to "having a specific rectified voltage", and the microprocessor cannot still output its voltage: it is directly controlled, and it is not possible to directly direct the DC to DC carrier frequency according to the present invention. The primary side line diagram of the transformer performs high-frequency pulse width adjustment and winter switch control to realize direct closed loop control of the charging voltage and current state. SUMMARY OF THE INVENTION The present invention proposes to use a built-in or external analog converter (milk converter) and a pulse width modulation (PWM) peripheral central unit, such as a micro-processor (MCU or DSP), from DC to The secondary side of the DC high-frequency transformer directly performs high-frequency pulse width modulation and intestinal switching control on the switching element of the f-side coil; and proposes a motor-driven switching element located on the secondary side of the high-frequency transformer, by using the above-mentioned central carrier soap element The other pulse width modulation output channel sends a pulse width double signal to the motor drive switch relative to the motor drive command, and changes the wheel power of the motor to achieve a function with a single central unit and provide electric power. The control battery and the circuit module of the electric vehicle battery for the exchange charging and the electric vehicle motor power control. Because the central control directly controls the switching elements of the primary side coil of the DC-to-DC high-frequency transformer, the system can simultaneously complete the work of singular-to-DC high-frequency transformer alternation and charging transition control, which not only saves the prior art. In addition to the special-purpose power supply control in the primary side coil, the exchange charging controller controls the 200841554 * secret (four) rail regulator material, the second pick-up wheel power out 1, the current is straight and connected, and the guest goes to the prior art chowder. In the secondary side of the device, a "$ electric switch" is controlled by another 鳟 螂 元 元 控 刺 刺 _ _.

The battery pack. * · 1 · .. The charging voltage, current, and temperature are measured by the central unit and the control target, and the current, over voltage, and over overflow protection are determined. According to the design requirements, various control states of constant current, constant voltage, or pulse charging are entered. The present invention further proposes that the secondary side of the high frequency transformer drives the switching element 'by the pulse width modulation output channel of the central computing unit, Sending pulses relative to the motor drive command The wide-range variable signal to the motor drives the scale to change the output power of the motor. The function and timing of the motor-driven switch are two: 1. The central computing unit can be 'periodic' during charging without increasing the cost of the part. Actively turn off the charging switch, and instantly turn on the motor switch to make the motor consume power. The battery pack is extremely short-discharged. This action can eliminate the chemical polarization and temperature rise caused by the continuous charging of the battery pack due to 200841554', and improve the charging efficiency. - When the electric vehicle is running and the motor drive command is not zero, according to the horse's driving command from the driver, and referring to the electric meter m and the temperature state, the appropriate pulse width modulation signal is sent to the motor drive switch to reach According to the driver's purpose of changing the speed of the vehicle, it becomes a complete module for the exchange charging and motor speed control of an electric vehicle. The present invention is an electric vehicle charging and motor driving controller, whether charging the battery pack or driving the motor. The state of the battery pack discharge is not as long as the prior art is a system that operates independently, but by a single central operation list. Yuan Quanquan control, the battery management of the battery that has been the most difficult to control for a long time in electric vehicle technology can be solved by reducing the power consumption and recording and discharging state of the single central computing unit (4) (4). The invention is placed in the space occupied by the vehicle. It is similar to the current π-like _ motor controller for electric vehicles. It can be directly replaced with the current general motor controller directly in the electric vehicle, and there is no need to keep or choose the electric vehicle as the current market. A special charger or the so-called rectifier, transformer, etc. in the prior art. Or it can be fixed with the battery pack; it is convenient to be plugged and unplugged into the room for charging together with the battery pack, improving the operational structure and the ease of use. The central computing unit is placed on the secondary side of the DC-to-DC high-frequency transformer and is powered by the battery pack. When the battery pack is removed, the central computing unit has no power supply. Naturally, the DC-to-DC high-frequency transformer primary-side drive switch is sent to charge the 200841554 pulse wave. When the signal is unloaded, the plug of the city is plugged in, and it will not be like a special external charger or previous technology. So-called rectifier, even if the battery is changed stag Wei branch line of additional specific properties and can still have it unnecessary to power shortage very edge of the battery pack contact redeemed, in addition to this the present hair ^. , . . . . . . . : : The above is revealed by the Ming Ming Ming, the valve is in the _ the person of this art, .! 丨. · · ' : Jiang is very easy board #何改变, This is a departure from the 鮝 鮝 之 珅 珅 畴. { ! * ·— ...·.心... . . if Shi Fangwu j Figure 1 Debenfare is more than a 'lack of "Luochi" Guangli exchange charger and Uda hearing and control circuit first-hand frame suspected implementation, and by +Yang Lian shrine unit illusion,...'

(Another principle of exchange of martial arts is based on the principle of r Shun Shang). Those who are familiar with this skill can easily derive from the spirit of the present invention, and will not be described here. In the non-driving state, that is, the motor drive command 28 In other words, after the motor drive switch 22 is turned off, the central operation unit 21 continuously feeds the pulse signal of the low conduction ratio from the other channel, and the high-speed optical coupler or the pulse transformer is used to isolate the component 32 to the DC-to-DC high-frequency transformer. Side switching element μ. After the mains plug 11 is plugged in, the AC power is passed through the filter 12 and the AC-DC full-wave rectifying diode 13 to obtain the high-voltage DC input on the primary side of the DC-to-DC high-frequency transformer 31 (if Wei Wei, after rectification) The voltage of the money is about W0V). When the switching element 14 performs the high-frequency switching operation, the central computing unit 21 will detect the diode throwing high-frequency transformer by the analogy digital device (〇200841554 31 secondary side coil) When the induced voltage 23 is generated, it can be judged that the mains plug u has been inserted and ready to enter the state of charge.
