The invention relates to an elevator braking force accurate-detection method based on an elevator balance coefficient, and relates to the field of elevator control. According to the method, by considering an eccentric load toward a counterweight direction when an elevator is no-load, the detection on an elevator with any balance coefficient can be realized; and by using an output current for beingrelated with a balance coefficient when the elevator goes down at stable speed in a non-load state, and by utilizing the two characteristic parameters of the elevator, a current is related with an elevator load through a torque, and an accurate detect current value is given, so that whether a braking force meets an index considered according to a rated load in the national standard or not is accurately detected. The method is short in detection time without affecting the normal use of the elevator, reasonable periodic automatic detection can be set, and the braking force of the elevator can completely guarantee the safe and reliable operation of the elevator if the detection is qualified, so that the compulsive requirements on the braking force and the braking force verification mentionedin the national standard GB7588-2003 Elevator Manufacture and Installation Safety Specification and the GB7588-2003 Number One Modification List are met.
