(54) BATTERY CELL, BATTERY, AND ELECTRIC APPARATUS


(57) A battery cell, a battery and an electricity-consuming device are provided by the present application. The battery cell includes a casing and a connecting terminal. The casing includes a mounting hole. The connecting terminal is at least partially arranged in the mounting hole, insulated from the casing, and configured for information exchange between an interior and an exterior of the battery cell. The battery cell provided by the present application can achieve the information exchange between the interior and the exterior of the battery cell, so as to transmit the information such as the working condition at the interior of the battery cell to the exterior of the battery cell, or transmit the information such as a control signal from the exterior the battery cell to the interior of the battery cell, thereby facilitating the information exchange between a related component inside the battery cell and a related component outside the battery cell, ensuring the normal operation of the battery cell, and improving the safety performance of the battery cell.
