Abstract: A battery pack (100) and a vehicle including the battery pack (100) are provided. The battery pack (100) includes a housing, a battery core group (20), and a distribution box (30) detachably mounted on the housing. The housing is provided with a receiving space (101). Both the battery core group (20) and the distribution box (30) are received in the receiving space (101). The battery core group (20) is electrically connected to the distribution box (30). The housing includes a bottom plate (11) and an access cover (12). The bottom plate (11) is provided with an access port (110). The access port (110) communicates with the receiving space (101). The distribution box (30) faces the access port (110). The access cover (12) is detachably mounted on the bottom plate (11) and covers the access port (110).

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.

Abstract: A copper bar protection structure (10) includes an upper housing (11) and a lower housing (12) that are engaged with each other. A receiving groove (14) is provided on each of engagement surfaces (15) of the upper housing (11) and the lower housing (12). The two receiving grooves (14) are combined into a copper bar accommodating space. A phase change material layer (30) is laid on an inner wall (13) of the receiving groove (14). The copper bar (20) is wrapped by the phase change material layer (30) when the copper bar accommodating space accommodates a copper bar (20).
