市場促進因素

電動車生產規模的擴大將拓寬外殼的潛在市場。

• 電動車產量的擴張是電池外殼需求的最直接促進因素。所有驅動電池都需要具備機械和環境防護功能的殼體。隨著全球電動車銷量的成長，對電池外殼的需求也與汽車產量成正比成長。
• 由於電池機殼是可重複生產的零件，而非使用一次性設備製造，因此大規模生產的汽車平臺有利於市場發展。此外，電動車製造業的擴張也促使供應商在車輛組裝廠和電池生產設施附近建立生產基地。

結構化的電池架構提升了機殼的價值。

• 電池外殼設計正從傳統的保護托盤演變為多功能結構組件。 「電芯-電池包」和「結構-電池包」架構減少了中間結構，並擴展了外殼在整個電池系統中的作用。
• 電池外殼在支撐電池負載、承受碰撞力、容納溫度控管系統以及促進底盤整合方面發揮越來越重要的作用。採用一體成型和減少焊接點的設計概念，在進一步提高電池組內部空間利用率的同時，也減少了接頭數量和組裝步驟。
• 這些技術進步增加了每個外殼的工程複雜性。具備結構設計、熱整合、密封和先進製造能力的供應商可以滿足更廣泛的汽車平臺的需求。

材料競爭正在轉向「整個系統的成本」。

• 汽車製造商在評估車身外殼材料時，不再只考慮減輕重量。碰撞安全性、製造成本、氣密性、可修復性、耐腐蝕性、熱性能、生命週期排放以及黏合要求等因素正日益成為重要的選擇標準。
• 鋼材憑藉其成熟的汽車供應鏈、大批量沖壓成型能力、優異的碰撞性能和低廉的材料成本，仍然是極具吸引力的選擇。鋁材則具有重量輕、耐腐蝕等優點。複合材料解決方案為電氣絕緣、耐腐蝕、降低品質和零件整合提供了可能。混合結構透過結合不同的材料，平衡了結構和製造方面的要求。
• 這創造了一個多材料市場，無論汽車平臺或電池配置如何，各種解決方案都能保持有效。

市場限制因素

認證和平台專用模具

• 電池外殼是關鍵的安全部件，需要進行全面的檢驗。供應商必須滿足衝擊、擠壓、防火、密封、耐腐蝕和高壓保護等方面的要求。這些認證要求可能會增加開發時間和投資。
• 此外，外殼與車輛底盤和電池系統緊密整合。一旦選定特定汽車平臺的設計方案，由於模具、工程整合和檢驗的要求，更換供應商將變得十分困難。因此，在平台開發和採購階段，競爭的激烈程度是一個特別重要的因素。
• 平台專用模具也會增加引入新製造概念的成本和複雜性。雖然整體成型和大規模成型可以降低組裝複雜性，但它們需要強大的模具和製程開發能力。

第13章附錄

The global EV battery enclosures market is forecast to grow at a CAGR of 12.0%, reaching USD 20.4 billion in 2031 from USD 11.6 billion in 2026.

The global EV battery enclosures market is becoming increasingly important as electric vehicle production expands and battery systems take on greater structural and functional roles. Battery enclosures must protect cells and high-voltage electronics from impact, water, dust, corrosion, and thermal events. They also support grounding, electromagnetic compatibility, vehicle mounting, cooling interfaces, and thermal-propagation protection. These requirements make the enclosure a highly engineered vehicle component.

Market development is closely linked to the expansion of electric vehicle production. Increasing EV volumes create a larger recurring demand base for battery housings. At the same time, vehicle manufacturers are evaluating steel, aluminium, composite, and hybrid solutions based on crash performance, weight, cost, manufacturability, sealing, repairability, thermal integration, and lifecycle considerations. The market is therefore moving toward platform-specific material and architecture decisions rather than a single material solution.

Asia Pacific remains the principal production base because of the region's strong electric vehicle manufacturing ecosystem. China accounts for a major share of global EV production and supports extensive battery, automotive, metal processing, and enclosure manufacturing capacity. Europe and North America are also strengthening local battery and EV supply chains, creating opportunities for regional enclosure production and supplier localization.

Market Drivers

EV Production Scale Expands the Addressable Enclosure Base

• The growth of electric vehicle production is the most direct driver of battery enclosure demand. Every traction battery requires a mechanically and environmentally protected housing. As global electric-car sales increase, enclosure requirements expand alongside vehicle volumes.
• The market benefits from high-volume vehicle platforms because battery enclosures are recurring production components rather than one-time manufacturing equipment. The expansion of EV manufacturing also encourages suppliers to establish production capacity close to vehicle assembly and battery facilities.

Structural Battery Architectures Increase Enclosure Value

• Battery enclosure designs are evolving from conventional protective trays toward structural components that perform multiple functions. Cell-to-pack and structural-pack architectures reduce intermediate structures and increase the enclosure's role within the overall battery system.
• The enclosure increasingly carries battery loads, reacts to crash forces, supports thermal systems, and contributes to underbody integration. One-piece and reduced-weld concepts further improve internal pack-space utilization while reducing the number of joints and assembly operations.
• This evolution increases the engineering content of each enclosure. Suppliers with capabilities in structural engineering, thermal integration, sealing, and advanced manufacturing can address a broader range of vehicle platform requirements.

Material Competition Is Shifting Toward Total System Cost

• Automakers are assessing enclosure materials beyond weight reduction. Crashworthiness, manufacturing cost, sealing, repairability, corrosion resistance, thermal performance, lifecycle emissions, and joining requirements are becoming important selection factors.
• Steel remains attractive because of its established automotive supply chain, high-volume stamping capabilities, crash performance, and lower material cost. Aluminium offers lightweighting and corrosion-resistance benefits. Composite solutions provide electrical isolation, corrosion resistance, low mass, and opportunities for part integration. Hybrid architectures combine different materials to balance structural and manufacturing requirements.
• This creates a multi-material market in which different solutions can remain relevant across vehicle platforms and battery configurations.

Market Restraints

Qualification and Platform-Specific Tooling

• Battery enclosures are safety-critical components and require extensive validation. Suppliers must address impact, crush, fire, sealing, corrosion, and high-voltage protection requirements. These qualification requirements can increase development time and investment.
• Enclosures are also closely integrated with vehicle underbodies and battery systems. Once a design is selected for a vehicle platform, tooling, engineering integration, and validation requirements make supplier substitution difficult. As a result, competitive intensity is particularly important during platform development and sourcing.
• Platform-specific tooling can also increase the cost and complexity of adopting new manufacturing concepts. One-piece designs and large-format molding can reduce assembly complexity, but they require substantial tooling and process-development capabilities.

Technology and Segment Insights

Material

• Steel, aluminium, composite, and hybrid materials represent the major material segments. Steel remains important for cost-efficient crash protection and established stamping and joining processes. Its higher mass compared with alternative materials remains a consideration where vehicle lightweighting is a priority.
• Aluminium provides a strong weight-to-strength balance and supports modular architectures using extrusion, stamping, casting, and welding. It is particularly attractive for larger battery packs where weight reduction can offset higher material and joining costs.
• Thermoplastic composites are gaining attention because they can provide electrical isolation, corrosion resistance, low mass, and greater part integration. Composite-metal hybrid systems combine different material properties and can balance crash strength, lightweighting, and multifunctional integration.

Vehicle Type

• Passenger battery-electric vehicles represent the largest enclosure demand because they account for the majority of global electric-car volumes. Their high production volumes create significant recurring demand for battery housings.
• Plug-in hybrid electric vehicles use smaller battery systems but provide additional enclosure demand in markets where hybrid vehicle adoption remains important. Commercial electric vehicles represent a smaller but potentially higher-value opportunity because trucks and buses can require larger and more robust enclosures. These vehicles may also use modular or multiple battery-pack configurations.

Enclosure Architecture

• Conventional multi-piece enclosures remain widely used. However, the market is moving toward one-piece, reduced-weld, cell-to-pack, structural-pack, and hybrid architectures.
• One-piece and reduced-weld designs aim to improve leak tightness, reduce joints, lower assembly complexity, and increase usable battery-pack space. Cell-to-pack and structural-pack architectures further increase the enclosure's structural and integration responsibilities.
• The pace of adoption depends on vehicle platform redesign cycles because the enclosure is closely connected to the vehicle underbody and battery architecture.

Manufacturing Process

• Stamping and welding remain important for steel enclosure production. These processes benefit from established automotive manufacturing infrastructure and high-volume production capabilities.
• Aluminium enclosures typically combine extrusion, stamping, casting, and welding. Casting can support structural integration, while extrusion-based designs can provide modularity and lightweight structures.
• Composite housings use compression molding or injection molding and may incorporate structural inserts or metal frames. Advanced deep drawing, roll forming, and large-format molding are being developed to reduce component counts and improve dimensional consistency.

Geography

• Asia Pacific is the principal production region for EV battery enclosures. China leads in electric vehicle manufacturing and supports a broad ecosystem of vehicle plants, battery factories, material suppliers, and automotive component manufacturers. Japan and South Korea contribute advanced materials, joining technologies, and automotive structural engineering. India is emerging as a localization market as domestic EV platforms expand.
• North America and Europe are strengthening local battery and EV supply chains. This is creating opportunities for regional enclosure manufacturing and supplier localization. South America and the Middle East and Africa provide additional opportunities as electric mobility develops across selected markets.

Competitive and Strategic Outlook

• The competitive landscape includes global Tier 1 automotive suppliers, specialist battery-system companies, and material producers. Key companies include Magna International, Gestamp Automocion, Kautex Textron, Benteler International, Minth Group, Nemak, thyssenkrupp, Novelis, Constellium, Hydro Extrusions, Shape Corp., Metalsa, SGL Carbon, SABIC, Rochling Automotive, Autoneum, Hanwha Advanced Materials, and GF Casting Solutions.
• Competition is increasingly based on complete-system capabilities rather than material supply alone. OEMs require validated crash performance, sealing, fire protection, high-volume tooling, joining expertise, and local production capabilities. Suppliers that integrate thermal interfaces, underbody protection, structural functions, and assembly optimization can increase their value within vehicle programs.
• Recent developments indicate continued investment in advanced enclosure architectures. Kautex has secured enclosure awards involving composite structures and thermal-management solutions. Magna has advanced one-piece deep-drawn enclosure concepts designed to reduce joints and improve internal pack-space utilization. thyssenkrupp has introduced recycled-content steel into series production involving a vehicle battery housing. Collaboration among aluminium and automotive component companies is also supporting new roll-form-intensive battery-tray concepts.
• The strategic direction of the market is therefore centered on lightweighting, structural integration, manufacturing efficiency, thermal protection, sealing performance, and material optimization. Suppliers must also consider regional production requirements because large battery enclosures are costly to transport over long distances. Localization near vehicle and battery manufacturing facilities can support supply-chain efficiency.

Conclusion

• The EV battery enclosures market is expanding alongside global electric vehicle production and the increasing functional importance of battery systems. Growth is supported by rising EV volumes, structural battery architectures, lightweighting requirements, and demand for integrated thermal and safety functions.
• Steel, aluminium, composites, and hybrid solutions will continue to compete across different vehicle platforms. At the same time, one-piece, reduced-weld, cell-to-pack, and structural-pack architectures are increasing the technical importance of the enclosure. Asia Pacific is expected to remain the principal production base, while localization in Europe, North America, and emerging EV markets creates additional opportunities. Competitive success will depend on material expertise, advanced manufacturing, platform-level engineering, validation capabilities, and localized production.
