Abstract: A smart connection sheet includes a conductive connection member and a cut-off apparatus. An end of the conductive connection member is adapted to connect to a terminal of a battery core of a battery pack, and another end of the conductive connection member is adapted to connect to a terminal of an adj acent battery core of the battery pack, to implement a series connection between the two adjacent battery cores in the battery pack. When receiving a cut-off signal, the cut-off apparatus cuts off the conductive connection member, to disconnect the two battery cores connected to the conductive connection member.
