The utility model discloses an immersed battery pack and an energy storage system, and belongs to the technical field of batteries. The immersed battery pack comprises at least two battery modules and a base, a heat dissipation gap is formed between every two adjacent battery modules, the base is used for supporting the at least two battery modules, a plurality of heat dissipation flow channels are formed in the base and comprise two first heat dissipation flow channels and at least one gap heat dissipation flow channel, and the first heat dissipation flow channels are communicated with the gap heat dissipation flow channels. A second jet orifice formed in at least one gap heat dissipation flow channel can spray cooling liquid to the heat dissipation gaps, so that battery cells of the battery module can fully exchange heat with the cooling liquid, poor temperature uniformity caused by over-temperature of the battery cells is avoided, the cooling liquid can flow through each battery cell under the combined act
