A self-checking device and a self-checking method for an elevator brake device, as well as an elevator system. The self-checking device includes: a controller, which controls a voltage applied to an electromagnetic coil of the elevator brake device, and which is configured to: enable an elevator to enter a test mode; gradually increase the voltage applied to the electromagnetic coil of the brake device in a predetermined pattern when the brake device is in a braking state, or gradually decrease the voltage applied to the electromagnetic coil of the brake device in a predetermined pattern when the brake device is in a non-braking state; and a processor, which is configured to receive and record a first time t1 when a brake switch of the brake device is triggered, and determine whether the brake switch is in a proper position based on the first time t1.
