First of all, high-quality battery trays should have good airtightness to prevent impurities, moisture, and gas mixing inside the battery, thereby ensuring the normal working state and life of the battery. Secondly, the airtightness design of the battery tray can effectively maintain the stability of the internal environment of the battery, prevent heat loss and temperature fluctuations, and thus improve the performance and life of the battery. And when the battery leaks or other abnormal conditions, the airtightness design can prevent harmful substances from leaking and avoid pollution and harm to the surrounding environment. In summary, airtightness is one of the most important detection indicators in battery pack trays, but the current existing battery trays cannot effectively resist external pressure and impact, thereby protecting the internal battery cells from damage.

[0023] The frame 1 is welded from high-strength steel. After welding, the frame 1 is electrophoretically treated as a whole. The tensile strength grade of the selected steel is not less than 600MPa, which meets the strength, rigidity and collision and extrusion safety of the battery pack tray.

[0024] The frame 1 includes side beams 11 and inner beams 12, which are perpendicular to each other and connected to form a cross shape. The cross-shaped inner beams 12 are perpendicularly connected to the opposite side beams 11. The frame 1 material is processed by laser cutting, CNC bending and other processes to form the required shape and size.
