A battery tray assembly includes a tray and an electrically conductive member disposed in the tray. The tray includes a mounting space configured to accommodate a battery assembly, and is electrically isolated from the battery assembly. At least a portion of the electrically conductive member is located in the mounting space. One end of the electrically conductive member is connected to a potential point. When no electrically conductive medium is disposed in the mounting space, the electrically conductive member is configured to provide a first potential signal between the battery assembly and the potential point. When the electrically conductive medium is disposed in the mounting space, the electrically conductive member connects the battery assembly to the potential point through the electrically conductive medium, to provide a second potential signal between the battery assembly and the potential point.

A battery pack including a pack housing including a beam partitioning an internal space; a plurality of battery modules including a plurality of battery cells and accommodated in each of spaces partitioned by the beam of the pack housing; and a barrier disposed in at least one an outside of the battery module and an inside of the battery module, wherein the barrier includes a barrier housing; a phase change material (PCM) inserted into an inside of the barrier housing and melting at a predetermined temperature or higher; and a discharge hole provided in the barrier housing and through which the molten phase change material is discharged, is disclosed.

A side beam for a battery tray is provided. The battery tray has an accommodating groove for accommodating a battery core. The side beam includes a first body and a second body. The first body includes a main portion and a supporting portion, and the supporting portion is connected to the main portion and is configured to support the battery core. The second body is fixed to the first body. The second body and the first body are separated workpieces. At least a part of the second body is located on a side of the supporting portion away from the accommodating groove.

A tray assembly includes a bottom plate that includes a main body portion and a raised edge portion, an expansion beam, and a first sealing member. The main body portion defines an accommodating cavity configured to accommodate a battery, and the raised edge portion is located on a peripheral of the main body portion and around the main body portion. The expansion beam is disposed on a first side of the raised edge portion and is configured to abut with the battery. The first sealing member includes a first portion disposed between the expansion beam and the raised edge portion.

Battery pack includes the following elements: large number of battery cells; lower holding member provided to hold the lower parts of large number of battery cells aligned by battery holding parts, and having lower openings for exposing the negative electrode terminal side of the battery cells; a positive electrode current collecting plate and a negative electrode current collecting plate connected to the corresponding terminals of the battery cells; and holder formed of upper holding member and lower holding member. In holder, upper gas channel for guiding the gas jetted from battery cells to the front side is formed. Inside holder, lower gas channel is formed on the periphery of the large number of battery cells. In holder, exhaust port is formed. In upper holding member, a communication hole for allowing communication between upper gas channel and lower gas channel is formed.

The invention concerns a battery holder (1) for an electric or hybrid motorized transport vehicle, the battery holder (1) comprising a frame (3) comprising at least one frame part (9) being configured to absorb all or part of shocks by an external element (7) likely to be applied to the battery holder (1).

The frame part (9) comprising at least one internal profile (10) and at least one external profile (30), said at least one internal profile (10) being positioned between said at least one external profile (30) and the floor (5).

The at least one internal profile (10) is formed from a first material having a first yield strength value, and the at least one external profile (30) is formed from a second material distinct from the first material and having a second yield strength value.

The invention also concerns a manufacturing process of a battery holder (1).
