The present utility model discloses a battery case and a battery pack, comprising: a housing, for accommodating a battery module; multiple support beams arranged on a wall of the housing, for contiguously supporting the accommodated battery module; wherein a corresponding space region is formed between at least two adjacent support beams of the multiple support beams when the battery module is contiguously supported, the space region forming a pressure relief cavity for a gas vent valve at the bottom of the battery module to vent gas into. The present utility model uses multiple support beams to provide weight support for the battery module, without any need for the whole of a bottom face of the battery module to be adhered to the housing; thus, the space region formed is ingeniously used as a pressure relief cavity which is isolated from a high-voltage connection chamber of the battery pack, and gas vented by the battery module during thermal runaway does not need to pass through a weak point, so the process of battery module gas venting is smooth. Furthermore, the present utility model has the advantages of being low-cost with a simple structure, and being easy to manufacture.
