Beschreibung
Zusammenfassung:	The invention relates to the technical field of battery cell control, in particular to a constant-voltage and constant-power output control method and circuit, a PCB and a BMS system. The method is used for controlling a power supply to output voltage with constant power to a motor, and comprises the following steps: pulling up the voltage of a negative port of an output port of a circuit according to the voltage of a positive port of the output port of the circuit; the PWM signal processing module is used for collecting, calculating and processing an anode voltage signal and a cathode current signal of the power supply and a voltage signal of a negative port of an output port of the circuit so as to modulate a PWM wave signal for controlling a switch module to switch on and off; and the switch module is controlled in a closed-loop manner through the PWM wave signal, and the negative electrode of the power supply and the negative port of the output port of the circuit are conducted, so that voltage with const
