A battery pack (200), a battery energy storage system (300), and an electric car (1000) are provided. The battery pack (200) includes a battery module (210) and a pressure sensing apparatus (220), where the battery module (210) includes a plurality of hard battery cells (211, 213) and two end plates, the two end plates being separately disposed along a thickness direction of the hard battery cells (211, 213) for tightly pressing the plurality of hard battery cells (211, 213) and the pressure sensing apparatus (220) that is disposed between the two end plates; and the pressure sensing apparatus (220) includes a first pressing plate (221) and at least one pressure sensor (222) disposed on the first pressing plate (221), the first pressing plate (221) being disposed on a first hard battery cell (211) and fully covering a surface of the first hard battery cell (211). The first pressing plate (221) is configured to transfer an expansion force in the thickness direction of the hard battery cells to the at least one pressure sensor (222), and the at least one pressure sensor (222) is configured to monitor the expansion force. The battery pack (200), the battery energy storage system (300), and the electric car (1000) have simple structures and can improve safety performance.
