A motor driving apparatus is disclosed, including a driving circuit (201) outputting a three-phase alternating current and a main controller (202). The driving circuit (201) includes a U-phase electric driving circuit (2011), a V-phase electric driving circuit (2012), and a W-phase electric driving circuit (2013). Each of the electric driving circuits includes n storage batteries and n electric driving units in one-to-one correspondence with the n storage batteries. Signal ends of the n electric driving units are connected to the main controller (202), input ends of the n electric driving units are connected to the corresponding storage batteries, and output ends of the n electric driving units are cascaded to output one phase of the three-phase alternating current, where n is a positive integer. The main controller (202) determines, for each electric driving circuit in the driving circuit (201), an output voltage adjustment coefficient of each of the n electric driving units in the electric driving circuit based on voltages of the n storage batteries in the electric driving circuit, and outputs the output voltage adjustment coefficient to the corresponding electric driving unit. The apparatus can improve storage battery utilization.
