BATTERY PACK AND VEHICLE

A battery pack and a vehicle is provided. The battery pack includes a first partition piece (31), a battery row (41), and a shielding member (43). The first partition piece (31) is located between two batteries (411) adjacent to each other in a first direction (W) in the battery row (41). An upper s...

description A battery pack and a vehicle is provided. The battery pack includes a first partition piece (31), a battery row (41), and a shielding member (43). The first partition piece (31) is located between two batteries (411) adjacent to each other in a first direction (W) in the battery row (41). An upper surface of the first partition piece (31) is lower than an upper surface of a top cover (411a). A recess (S) is formed between the battery row (41) and the first partition piece (31). The shielding member (43) includes a first shielding portion (431) and a second shielding portion (432). The first shielding portion (431) overlays all explosion-proof valves (411b) of the battery row (41). A passage (P) is disposed between the first shielding portion (431) and the upper surface of the battery row (41). The passage (P) is configured to guide a fluid to flow along the first direction (W) and is provided with a downward opening (O). The second shielding portion (432) closes off a part of the opening (O) facing the recess (S) directly. By setting the second shielding portion (432) to closes off a part of the opening (O), the part facing the recess (S) directly. A fluid generated by thermal runaway can be effectively prevented from flowing into the recess (S), more reliably achieves directional expulsion of the thermal runaway fluid, and enhances safety performance of the battery pack.
