An elevator brake performance detection method includes controlling an input voltage or current of the electromagnetic member so that the elevator brake enters the braking state, and recording a corresponding current data trajectory of the electromagnetic member based on time characteristic; determining a first target point and a second target point in the current data trajectory according to the current data trajectory, the first target point and the second target point being a first peak point in the current data trajectory, and a start point at which the current value changes from decreasing to increasing in the current data trajectory, respectively; and calculating a time difference between the first target point and the second target point as a braking time of the elevator brake.
