Abstract
Provided is a drive module. A main control unit in the drive module is configured to determine, according to the output voltage of the electrical energy storage unit, an optimal analog reference voltage output efficiency value of a power supply chip, determine, according to the output voltage of the electrical energy storage unit and the optimal analog reference voltage output efficiency value of the power supply chip, a voltage value of an analog reference voltage, and generate, according to the voltage value of the analog reference voltage, a control instruction corresponding to pulse signal information. A pulse signal generation unit is configured to generate a corresponding pulse signal according to the control instruction. An analog reference voltage unit in the power supply chip is configured to receive an electrical signal output by the electrical energy storage unit, and generate, according to the pulse signal, a corresponding analog reference voltage signal.
