Abstract

The invention relates to a voltage control device for a metal-air battery. The voltage control device comprises a voltage detection circuit, a voltage control circuit, an output control switch, an ideal diode circuit and a DC / DC module with the off function. The invention further relates to a method for controlling the voltage through the voltage control device. The method includes the steps that the working state of the output control switch and the working state of the DC / DC module are controlled by detecting the voltage of the metal-air battery; when the voltage of the battery is within a load rated operational voltage range, the battery outputs electric energy through the output control switch; when the voltage of the battery is not within the load rated operational voltage range, the battery outputs the electric energy after the DC / DC module carries out voltage stabilizing. By means of the method, it can be guaranteed that the output voltage of a battery system meets the load requirement, and the electric energy losses caused by a voltage stabilizing device can be reduced as far as possible.

Description

technical field [0001] The invention relates to a voltage control method for a metal-air fuel cell, which controls the working state of an output control switch and a DC / DC module by detecting the voltage of the metal-air cell. When the battery voltage is within the rated operating voltage range of the load, the battery outputs electric energy through the output control switch; when the battery voltage is outside the rated operating voltage range of the load, the battery outputs electric energy after being regulated by the DC / DC module. This method can not only ensure that the output voltage of the battery system meets the load requirements, but also reduce the power loss caused by the voltage stabilizing device as much as possible. Background technique [0002] Metal-air batteries use oxygen in the air as the positive electrode active material, and metal zinc, magnesium, aluminum, etc. react to release electricity. There is a certain difference between the open circuit vo...
