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.

Abstract: A battery assembly includes a protection member and a battery module including at least two batteries arranged side by side along a first direction and having a first outer surface and a second outer surface opposite to each other along a second direction. The protection member is in the form of a letter U with two vertical portions having different lengths, wherein a first protection section covers the end covers of batteries in the battery module, a part of a second protection section covers the first outer surface, and a third protection section abuts against an end cover of a battery corresponding to the second outer surface. The protection member can prevent the airflow, the flame and the like sprayed during thermal runaway, and control a thermal diffusion range during thermal runaway.
