Mouse and mouse pad capable of being charged automatically and wirelessly and charging method of mouse and mouse pad

The invention discloses a mouse and a mouse pad capable of being charged automatically and wirelessly and a charging method of the mouse and the mouse pad. The mouse comprises a signal emission module, a voltage detection module, a first micro-controller, a wireless receiving coil array and a rechargeable battery; the mouse pad comprises a mouse pad body, a transmission coil array, a USB port, a boosting module, a signal receiving module and a second microprocessor. When the voltage of the rechargeable battery is lower than a preset first voltage threshold, a charging signal is sent to the mouse pad, all drive circuits of the transmission coil array are started, transmission coils in the transmission coil array are connected selectively for energy transmission through detection of the coupling degree between each transmission coil in the transmission coil array and the receiving coil array, a charging stop signal is sent to the mouse pad when the voltage of the rechargeable battery is sufficient, and all the
