Abstract: A copper bar protection structure (10) includes an upper housing (11) and a lower housing (12) that are engaged with each other. A receiving groove (14) is provided on each of engagement surfaces (15) of the upper housing (11) and the lower housing (12). The two receiving grooves (14) are combined into a copper bar accommodating space. A phase change material layer (30) is laid on an inner wall (13) of the receiving groove (14). The copper bar (20) is wrapped by the phase change material layer (30) when the copper bar accommodating space accommodates a copper bar (20).

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.
