The embodiment of the invention provides a valve, a battery pack and an electric vehicle. The valve is applied to the battery pack, the valve comprises a plurality of supporting plates, a first fixingplate, a sliding plate, a first elastic piece and a clamping piece, wherein the plurality of supporting plates are arranged at intervals on the same plane to form a gap, the sliding plate is arrangedon the other side, close to the gap, of the supporting plate in parallel, one end of the first elastic part is arranged on the first fixing plate at one side of the gap, the other end of the first elastic part is fixed on the sliding plate at the other side of the gap, a clamping piece used for clamping the sliding plate is arranged on the supporting plate, when the clamping piece releases the clamping lock of the sliding plate, the sliding plate moves towards the gap under the action of the first elastic piece, and finally the sliding plate shields the gap. When the temperature in the battery rises to enable the clamping lock piece to release the clamping lock of the sliding plate, the gap is blocked by the sliding plate, the damage to a human body caused by the fact that high-temperature harmful gas in the battery pack enters the passenger compartment is avoided.
Description
technical field [0001] The present application relates to the field of power batteries, in particular, to a valve, a battery pack and an electric vehicle. Background technique [0002] Compared with the number of power batteries in pure electric vehicles, the number of power batteries in hybrid electric vehicles is much less. increase cost. Therefore, in order to cool or heat the power battery in the hybrid vehicle without additional cost, the prior art usually introduces the air in the passenger compartment into the battery pack to cool or heat the cells in the battery pack. [0003] The air in the passenger compartment enters the battery pack, and then the air is discharged into the passenger compartment from the air outlet channel. If the battery cells in the battery pack experience thermal runaway, the high-temperature harmful gas in the battery pack will be discharged from the air outlet channel. cause harm to the human body. [0004] How to prevent the battery cells...
