The invention discloses a battery pack, an electric vehicle and an energy storage device. A deformation sensing assembly in the battery pack comprises a plurality of deformation sensing units which are respectively arranged between two adjacent single batteries, and a deformation sensor which is arranged in a box body and is connected with the deformation sensing units and a battery management system. When the single battery deforms, the deformation sensing units can sense the deformation quantity when the single battery deforms, generate a change signal corresponding to the deformation quantity and transmit the change signal to the deformation sensor; and the deformation sensor generates a deformation sensing signal corresponding to the change signal and transmits the deformation sensingsignal to the battery management system, and the deformation sensing signal can be timely fed back to the battery management system when the single battery deforms, so that abnormal information of thebattery pack can be timely acquired, hidden dangers of the battery pack can be timely eliminated, and the battery pack is prevented from being on fire.
