The invention provides a control guide circuit, and relates to the technical field of charging control. The control guide circuit comprises a rectifier circuit, a first detection circuit and a second detection circuit. A power supply equipment control device generates a first alternating current square signal according to the power supply capacity of power supply equipment, the rectifier circuit rectifies the first alternating current square signal to generate a first direct current square signal, the first detection circuit generates a second direct current square signal according to the first direct current square signal, the second detection circuit generates a third direct current square signal according to the first direct current square signal, and a battery control device generates a voltage amplitude signal according to the second direct current square signal and a duty cycle signal according to the third direct current square signal. According to the control guide circuit, power supply capacity information of the power supply equipment can be sent to the battery control device so that the battery control device can send correct power supply request information to the power supply equipment control device.
Description
technical field [0001] The present invention relates to the technical field of charge control, in particular to a control and guidance circuit. Background technique [0002] With the depletion of traditional fossil energy and the increasingly serious environmental pollution, as well as the continuous development of electronic technology and control technology, electric vehicles have been widely used. Since the energy storage process of electric vehicles is more complicated than that of traditional fossil energy storage methods, an important factor that determines whether the performance of electric vehicles is good is the safety and reliability of the charging system. [0003] The charging system generally includes power supply equipment, power supply equipment control device, battery, battery control device, charger and other equipment. Through the information interaction of the above equipment, it can ensure that the power supply equipment can effectively charge the batter...
