The present invention provides a battery equalizing apparatus and method, and an unmanned aerial vehicle (UAV). The battery equalizing apparatus includes: a battery gauge configured to monitor battery level information of a battery in a static state, a battery equalizing circuit being disposed inside the battery gauge; and a microprocessor connected to a communication port of the battery gauge and configured to: acquire the battery level information monitored by the battery gauge, and calculate a pressure difference between cells of the battery in a static state according to the battery level information, and determine whether the pressure difference is greater than a pressure difference threshold; the microprocessor sending a trigger signal to the battery gauge through the communication port when the pressure difference is greater than the pressure difference threshold, to trigger the equalizing circuit of the battery gauge to equalize the battery. Through implementation of the present invention, a space of a circuit board may be saved by using an internally integrated equalization function of the battery gauge, facilitating miniaturization of the battery.
