The invention discloses a battery quick-changing device which comprises a connecting rod and at least one lock body device, each lock body device comprises a cross beam, a first fixing plate, a secondfixing plate, a first clamping jaw, a second clamping jaw and an inverted-U-shaped frame, one end of each cross beam is fixedly connected with the corresponding first fixing plate, and the other endof each cross beam is fixedly connected with the corresponding second fixing plate; the lock body device is fixedly connected with a vehicle body frame through a first fixing plate and a second fixingplate. The first clamping jaw and the second clamping jaw are used for fixing a battery pack frame. The connecting rod is fixedly connected with the end, away from the supporting arm of the inverted-U-shaped frame, of the inverted-U-shaped frame, and the connecting rod is used for driving the inverted-U-shaped frame to move up and down. The invention further discloses an electric vehicle and a quick change method. Locking is achieved through the interaction between the lock body device and the connecting rod, the shaft pin can be quickly opened and stably released during battery replacement,the battery pack can be quickly disassembled, quick locking can be achieved when the battery pack is assembled in place, it is guaranteed that the battery pack is stable and reliable when a vehicle runs, and the requirements for strength and rigidity are met.
