PACK structural components—housing, end plates, and busbar brackets (Source: Stats): Key Rule: Seven major categories (Source: Emergen); Core: End plates and side plates account for the largest share (Source: PW); Note: 6061 aluminum CNC machining (Source: Jinlv).
I.
Housing Assembly
Lower Housing: Battery pack bottom tray (Source: Sumyi); Upper Cover: Top cover for sealing and isolation (Source: Douyin); Casing: Extruded profile casing (Source: Douyin); Material: Aluminum alloy or SMC composite (Source: Douyin); IP54: IP54 protection rating (Source: Alibaba)—Housing: Lower housing + Upper cover + Casing (three-piece set).
II.
End Plates and Side Plates
End Plate: Aluminum end plate (6061/6063) (Source: Jinlv); Side Plate: Module side plate (Source: PW); Process: Extrusion, sawing, CNC machining, and anodizing (Source: Jinlv); Dimensions: Standard 169×175×19.5mm (Source: Dagong); Lightweighting: Cut-outs for weight reduction and heat dissipation (Source: Dagong)—End Plate: Material, process, and lightweighting (three key points).
III. Busbar Brackets
Busbar: Busbar bracket (Source: astraion); Connection: Connection bracket (Source: astraion); Shield: Mounting plate (Source: astraion); Copper Busbar: Copper busbar connection (Source: hxcnc); Market Share: Busbar connections account for 24.71% of the market (Source: PW) — Busbar category: Bracket + Copper Busbar + Connection (three accessories).
IV.
Thermal Management Components
Liquid Cooling Plate: Liquid cooling plate/water-cooling heatsink (Source: sumyi); Baseplate: Module heat dissipation baseplate (Source: sumyi); Heat Spreader: Aluminum heat spreader (Source: sumyi); Heat Pipe: Heat pipe mounting plate (Source: sumyi); Market Share: Thermal management valued at $1,632.91 million (Source: PW) — Thermal management category: Liquid cooling + Heat spreader + Baseplate (three components).
V.
Auxiliary Components
Tray: Battery tray (Source: DRA); Baffle: Baffle/louver (Source: DRA); Cover Plate: Cable plate/gland plate (Source: DRA); Seal: Battery pack sealing gasket (Source: Emergen); Insulation: Insulation assembly (Source: Stats) — Auxiliary category: Tray + Seal + Insulation (three auxiliary parts).
VI. Key Selection Criteria
Material: 6061/6082 aluminum, C10100 copper (Source: BIE); Flatness: Flatness for IP sealing (Source: BIE); Thermal Conductivity: Thermal conductivity requirements (Source: BIE); Customization: Designed according to cell format (Source: astraion); Manufacturing Process: Laser welding, sheet metal fabrication (Source: Alibaba)—Selection focus: Material + Flatness + Thermal conductivity (Triple verification).
VII.
Procurement Recommendations
First, specify the housing (IP54 enclosure); second, select end plates (6061 CNC); third, configure busbars (busbar brackets); fourth, install liquid cooling (cooling baseplate);
fifth, apply seals (gaskets)—Structural components: Housing + End plates + Heat pipes (Three core elements).
