Disclosed are a bolt locking method, a bolt unlocking method, a bolt locking/unlocking control method, and a vehicle battery replacement method. The bolt locking method is used for a bolt locking device, which comprises a bolt screwing element and a locking-assisting check block used for providing a reaction force to adjust a screwing torque of the bolt screwing element; and the bolt locking method comprises: a docking step S110, wherein the bolt screwing element is driven to be centered and engaged with a bolt end at a first speed in a first set interval of numbers of screwing turns for docking, and at this moment the bolt screwing element abuts against the locking-assisting check block; and a locking step S120, wherein the bolt screwing element is driven to screw a bolt at a second speed in a set interval of numbers of screwing turns for locking until a screwing torque is increased to a set locking torque, and at this moment it is determined that the bolt is successfully locked; and meanwhile, the bolt screwing element counteracts the reaction force of the locking-assisting check block. With the bolt locking/unlocking method, effective protection of the bolt locking/unlocking process and flexible control of bolt locking/unlocking are achieved.
