Abstract: A battery pack for optimizing the structure of the battery pack includes a case, a battery module and a blocking member. The case includes an accommodating cavity and a drain hole in communication with the accommodating cavity. The battery module is contained inside the accommodating cavity. The blocking member is mounted to the case, and located between the drain hole and the battery module to block a binder for fixing the battery module from entering the drain hole. In the above-described technical solution, the blocking member can produce the effect of reducing or even avoiding binder for fixing the battery module from clogging in the drain hole.
