Abstract: The present disclosure relates to a power battery pack and a vehicle. The power battery pack includes a battery tray and several battery cells disposed on the battery tray. Each of the battery cells has a cell anti-explosion valve. The battery tray includes a tray body. At least a part of the tray body is formed therein with an air passage. The tray body is provided with several inlet vents and at least one exhaust vent. At least part of the inlet vents and the cell anti-explosion valves are disposed opposite to each other and correspond one-to-one to each other.

Abstract: The present disclosure relates to a battery tray and a power battery pack. The battery tray includes a tray body. The tray body includes a base plate and a side beam, and the side beam is disposed around the base plate and defines, together with the base plate, an accommodating space for battery cells. The base plate is formed therein with an air passage, and the base plate is provided with several inlet vents and at least one exhaust vent. The inlet vent is configured to introduce a flame, smoke or gas discharged from the battery cell into the air passage, and the exhaust vent is configured to discharge the flame, smoke or gas inside the air passage.

Abstract: Provided are a battery tray and a power battery pack. The battery tray includes a tray body. The tray body includes a base plate, a side beam, and several partition plates, the side beam is disposed around the base plate and defines, together with the base plate, an accommodating space for battery cells. The partition plates are disposed on the base plate and divide the base plate into several regions for placing the battery cells. The partition plates and the side beam are each formed therein with an air passage and are in communication with each other. The partition plates are provided with several inlet vents, and the side beam is provided with at least one exhaust vent. The inlet vent is configured to introduce a flame, smoke or gas discharged from the battery cell into the air passage.
