汽車整合起動發電機組市場機會、成長動力、產業趨勢分析及 2025 - 2034 年預測

2024年，全球汽車整合起動發電機市場規模達52億美元，預計到2034年將以8.9%的複合年成長率成長，達到119億美元。這一成長主要源於對兼具高能源效率和低環境影響的汽車日益成長的需求。隨著全球排放法規日益嚴格，汽車製造商正在加緊推出搭載ISG技術的輕度混合動力車型。這些系統對於那些追求更高燃油經濟性，但又不想承擔全混合動力或插電式混合動力汽車高昂價格的消費者來說極具吸引力。配備ISG的動力系統提供了一種折衷方案——在顯著節省燃油的同時，對傳統車輛設計的干擾最小。

人們對高階高性能車日益成長的需求也加速了ISG裝置的普及，因為它們有助於提升引擎啟動停止平順性，並帶來低速扭力提升，從而提升駕駛體驗。這完全符合高階買家的需求——既追求高效，又不犧牲動力和豪華體驗。隨著城市交通堵塞加劇，對降低怠速和頻繁停車油耗的系統的需求激增。 ISG裝置有助於應對這些挑戰，同時減少排放，使其成為推動更智慧、更環保的城市交通發展的熱門選擇。

2024年，皮帶傳動ISG系統市場規模達30億美元，憑藉為汽車製造商提供實用且經濟高效的電氣化途徑，佔據了市場主導地位。這些裝置安裝在引擎前端，並透過皮帶連接到曲軸，使製造商無需重新設計主要部件即可整合它們。對於希望快速實現現有車輛平台電氣化的品牌而言，這種簡化的整合方式是一大優勢，可節省時間和金錢。

輕度混合動力車在2024年佔據了最大的市場佔有率，預計仍將是關鍵的成長領域。這些車輛採用緊湊型電池，並帶來駕駛員能夠立即感受到的性能優勢——從滑行時的安靜運行到引擎的無縫重啟。低階扭力提升提升了駕駛性能，尤其是在走走停停的交通中。此外，輕度混合動力車不依賴外部充電，非常適合那些希望在不改變駕駛習慣的情況下獲得環保選擇的消費者。因此，這些系統在商用車隊和個人車輛中正變得越來越普遍。

2024年，德國汽車整合起動發電機組市場規模達4.967億美元。該國的主導地位得益於其成熟的汽車製造基礎以及48伏系統在各車型中的早期應用。領先的製造商已積極在其產品線中應用皮帶傳動ISG技術，以滿足法規要求和消費者期望。德國強大的供應鏈，包括博世、大陸集團和採埃孚等主要供應商，進一步支持了本地生產和創新，並幫助其在全球ISG市場保持競爭優勢。

活躍於全球汽車整合起動發電機組市場的主要參與者包括博世、三菱電機、電裝、博格華納、麥格納國際、採埃孚、索恩格汽車、大陸集團、日立阿斯泰莫和法雷奧。為了確保在汽車 ISG 市場的領先地位，各公司正專注於幾個策略領域。核心策略涉及投資研發，以提高性能、減輕重量並提高 ISG 系統的能源效率。製造商還瞄準平台可擴展性，以允許 ISG 整合到各種車輛類別中。與原始設備製造商的合作在為特定動力傳動系統客製化解決方案方面發揮關鍵作用。此外，公司正在透過在地化製造來增強生產能力，以縮短交貨時間並遵守區域採購政策。

The Global Automotive Integrated Starter-Generator Units Market was valued at USD 5.2 billion in 2024 and is estimated to grow at a CAGR of 8.9% to reach USD 11.9 billion by 2034. This growth is largely fueled by rising demand for vehicles that offer both improved efficiency and reduced environmental impact. As global regulations surrounding emissions become stricter, automakers are ramping up the rollout of mild hybrid models that incorporate ISG technology. These systems are attractive to consumers seeking better fuel economy without the steep price tag associated with full or plug-in hybrids. ISG-equipped powertrains provide a middle ground-delivering noticeable fuel savings with minimal disruption to conventional vehicle designs.

The growing appetite for premium and performance vehicles is also accelerating the adoption of ISG units, as they contribute to smoother engine start-stop operations and deliver low-end torque improvements that enhance driving feel. This aligns perfectly with what high-end buyers want-efficiency without sacrificing power or luxury. As congestion increases in urban areas, demand for systems that reduce fuel use during idling and frequent stops has surged. ISG units help manage these challenges while also reducing emissions, making them a favored option in the push for smarter, greener urban transportation.

In 2024, the belt-driven ISG systems segment generated USD 3 billion, dominating the market by offering automakers a practical and cost-effective route to electrification. These units are mounted on the engine's front and connected via a belt to the crankshaft, allowing manufacturers to integrate them without redesigning major components. This streamlined integration is a major advantage for brands looking to electrify existing vehicle platforms quickly, saving both time and capital.

Mild hybrid-electric vehicles represented the largest market share in 2024 and are projected to remain a key growth area. These vehicles incorporate a compact battery and deliver performance benefits that drivers can immediately notice-from quiet operation during coasting to seamless engine restarts. The low-end torque boost improves drivability, particularly in stop-and-go traffic. Additionally, mild hybrids do not rely on external charging, making them ideal for consumers who want eco-friendly options without changing their driving habits. As a result, these systems are becoming more common across both commercial fleets and personal vehicles.

Germany Automotive Integrated Starter-Generator Units Market generated USD 496.7 million in 2024. The country's dominant position is supported by a mature automotive manufacturing base and early adoption of 48-volt systems across various vehicle classes. Leading manufacturers have aggressively implemented belt-driven ISG technology across their lineups to meet both regulatory demands and consumer expectations. Germany's robust supply chain, with major contributors such as Bosch, Continental, and ZF Friedrichshafen, further supports local production and innovation, helping the country maintain a competitive edge in the global ISG market.

Key players active in the Global Automotive Integrated Starter-Generator Units Market include Bosch, Mitsubishi Electric, Denso, BorgWarner, Magna International, ZF Friedrichshafen, SEG Automotive, Continental, Hitachi Astemo, and Valeo. To secure a leading position in the automotive ISG market, companies are focusing on several strategic areas. One core strategy involves investment in R&D to enhance performance, reduce weight, and improve the energy efficiency of ISG systems. Manufacturers are also targeting platform scalability to allow ISG integration across various vehicle categories. Collaborations with OEMs play a key role in customizing solutions for specific drivetrains. In addition, firms are strengthening their production capabilities through localized manufacturing to reduce lead times and comply with regional sourcing policies.
