The embodiment of the invention discloses a power battery consistency test method and device, and belongs to the technical field of batteries. The method comprises the steps that in response to a first obtaining instruction, the voltage of each single battery in multiple single batteries in a target charge state is obtained, multiple first voltages in one-to-one correspondence with the multiple single batteries are obtained, and the target charge state indicates that the electric quantity of the power battery is the target electric quantity. In response to a second acquisition instruction, the voltage of each single battery in the multiple single batteries in the target charge state is acquired, multiple second voltages in one-to-one correspondence with the multiple single batteries are obtained, and the duration between the triggering time of the second acquisition instruction and the triggering time of the first acquisition instruction exceeds the reference duration. And testing the consistency among the plurality of single batteries based on the plurality of first voltages and the plurality of second voltages. According to the embodiment of the invention, the consistency among the plurality of single batteries in a period of time is tested, so that the consistency condition of the power battery is accurately described.
