전기차 올인원 통합 구동 시스템 시장 규모, 점유율 및 성장 예측(2026-2031년)

The global EV Multi-in-1 Integrated Drive Units Market is anticipated to grow from USD 2.40 billion in 2026 to USD 5.80 billion by 2031, at a CAGR of 19.3% across the forecast period.

Multi-in-1 electric drive architectures extend integration beyond the traditional traction motor, inverter and reduction gear. Additional functions can include the onboard charger, DC-DC converter, power distribution unit, battery management system, vehicle control unit, eFuse, charging boost circuitry and domain-control electronics. The architectural objective is not simply to place several devices in the same housing. Higher-value designs share semiconductor resources, cooling circuits, control processors and physical interfaces across functions. BYD's e-Platform 3.0 provides one of the clearest mass-production examples. Its 8-in-1 powertrain integrates the vehicle control unit, battery management system, motor control unit, power distribution unit, DC-DC controller, onboard charger, drive motor and transmission. BYD states that the architecture contributes to reduced overall size and weight while supporting high system efficiency. Geely has moved further toward 11-in-1 architectures. InfiMotion offers 11-in-1 electric drive units and a 9-in-1 power-domain controller. These systems show that the category is no longer confined to engineering concepts. The market covered here begins at five integrated functions and excludes conventional 3-in-1 e-axles. This boundary keeps the focus on deep integration of propulsion, charging and power-distribution functions rather than standard motor-inverter-reducer packaging.

Market Drivers

• OEMs are reducing hardware count and high-voltage interconnections. Each separately packaged inverter, charger, converter and power distribution device requires its own housing, connectors, cooling connections, mounting points and validation. Combining functions reduces duplicate mechanical content and can shorten high-voltage cables and coolant paths. Valeo states that its 5-in-1 deep-integration module reduces weight by around 20% through hardware and control consolidation. For high-volume EV programs, these savings can translate directly into lower material and assembly costs.
• Software and control integration are becoming as important as mechanical integration. The next stage of integration involves shared control processors and coordinated software. Valeo's 5-in-1 platform uses a common system-on-chip architecture for several power-electronics functions. BYD and Geely integrate vehicle- and battery-control functions inside broader electric-drive architectures. This reduces communication latency and hardware duplication but increases the validation burden because faults can affect several vehicle functions simultaneously.
• China is accelerating commercial adoption. Chinese EV manufacturers have moved faster than most global OEMs in integrating multiple propulsion and power-electronics functions. BYD's 8-in-1 architecture is already used across e-Platform 3.0 vehicles. Geely uses 11-in-1 systems on high-volume products. Leapmotor has deployed 7-in-1 drives. InfiMotion supplies multi-in-1 electric drive and power-domain platforms. China's shorter vehicle-development cycles and aggressive cost targets favor architectures that remove components and simplify final vehicle assembly.

Market Restraints

• Thermal coupling and repairability can offset integration benefits. Placing propulsion, charging and power-distribution functions into one compact module increases thermal interaction between semiconductors, motors and passive components. Cooling systems must handle different temperature limits and duty cycles inside a smaller package. Deep integration also creates repair challenges. Failure of one sub-function can make a larger module unavailable unless suppliers design replaceable subassemblies. These factors can limit adoption in vehicles where low service cost is more important than maximum packaging efficiency.

Technology and Segment Insights

• Shared semiconductor and controller architectures are a key technology direction. Deeply integrated modules increasingly share microcontrollers, gate-driver resources, sensing hardware and communication interfaces. This approach can reduce printed circuit board count and semiconductor duplication. It requires functional-safety partitioning so that a fault in one power domain does not propagate across unrelated vehicle functions.
• Integrated charging and voltage boost are expanding. Adding the onboard charger and DC-DC converter to the propulsion module allows manufacturers to combine magnetic components, coolant circuits and high-voltage distribution. Some X-in-1 designs also reuse motor windings or inverter hardware for voltage-boost charging. This reduces the number of dedicated high-power components needed elsewhere in the vehicle.

800 V and silicon carbide platforms increase the value of tightly coordinated multi-function modules. Higher-voltage EVs benefit from silicon carbide power devices because lower switching losses and greater temperature capability support higher power density. Multi-in-1 modules can distribute these benefits across traction, charging and conversion functions. The cost advantage depends on how much semiconductor and cooling hardware can genuinely be shared.

• Domain-control fusion is the most advanced direction. Architectures are moving toward powertrain-domain control rather than simply mechanical packaging. Battery management, vehicle control and electric-drive control can be coordinated through fewer processors. This enables faster torque response, energy optimization and over-the-air software updates. This direction links multi-in-1 hardware to the broader software-defined vehicle architecture.
• The market is segmented by integration level, functional scope, voltage architecture, vehicle type, supplier model and geography. Integration levels include 5-in-1, 6-in-1 and 7-in-1, 8-in-1, 9-in-1 to 11-in-1, and X-in-1 or higher integration. Functional scopes include power electronics integration, propulsion and power electronics integration, and propulsion, charging and domain-control integration. Voltage architectures include below 400 V, 400-799 V, and 800 V and above. Vehicle types include passenger battery electric vehicles, plug-in hybrid electric vehicles, commercial electric vehicles and other electric vehicles. Supplier models include vertically integrated OEM systems and Tier 1 modular platforms.
• Five- and six-function modules are often centered on power electronics. They combine the inverter, onboard charger, DC-DC converter and distribution or protection functions. Seven- and eight-function systems extend integration into the drive unit and vehicle control. Eleven-in-one and X-in-1 systems represent the most aggressive architectures. They typically combine propulsion hardware with charging, power distribution and domain-control electronics.
• Power-electronics-focused modules offer the lowest integration barrier because inverter, charger and DC-DC functions share semiconductor, magnetic and cooling technologies. Complete propulsion-domain modules add the motor and reducer. This increases mechanical complexity but also allows more substantial vehicle-level packaging gains. Controller-rich architectures can further reduce wiring and external electronic control units.

400 V systems remain important in high-volume compact EVs because semiconductor and insulation costs are lower. 800 V architectures are increasingly used in vehicles prioritizing fast charging and high sustained power. Multi-in-1 integration is particularly attractive at 800 V because every removed high-voltage connector, cable and enclosure has meaningful cost, mass and packaging value.

• Passenger battery-electric vehicles are the primary commercialization base because their production scale can amortize the engineering cost of deeply integrated modules. Plug-in hybrids use integrated power electronics but can require different packaging around the engine and transmission. Commercial EVs offer high component value but often favor serviceable and modular systems over the highest possible integration.
• Vertically integrated automakers such as BYD and Geely can optimize multi-in-1 systems around proprietary vehicle architectures. Tier 1 suppliers instead emphasize modularity so that a common platform can be adapted to multiple OEM electrical and mechanical interfaces. The two approaches create different competitive models. One is vehicle-level optimization. The other is broader customer scalability.

Competitive and Strategic Outlook

• Competition spans vertically integrated automakers, global Tier 1 suppliers and China-based electric-drive specialists. BYD and Geely develop deeply integrated systems around their own vehicle architectures. Huawei Digital Power and InfiMotion offer supplier platforms that can be adapted across multiple OEMs. Valeo is commercializing deep-integration power electronics for external customers. Nidec has positioned X-in-1 as the next evolutionary stage beyond its conventional e-axle portfolio.
• The central competitive issue is whether suppliers can deliver measurable vehicle-level cost and weight savings without increasing warranty and repair risk. Platform scalability, shared control electronics, electromagnetic compatibility, thermal design, functional safety and software integration are becoming as important as motor efficiency. Suppliers with both power-electronics and drivetrain expertise are best positioned to move from conventional 3-in-1 systems toward higher-value multi-function modules.
• Asia Pacific is the principal market for multi-in-1 EV drive units. China combines the world's largest electric-vehicle production base with the fastest commercialization of deeply integrated powertrain electronics. BYD has deployed its 8-in-1 system across multiple e-Platform 3.0 models. Geely's 11-in-1 drive is used in vehicles including the EX2 and EX5. Leapmotor's 7-in-1 system, InfiMotion's 11-in-1 products and Huawei DriveONE's X-in-1 platforms broaden the regional supplier base beyond a small number of vertically integrated OEMs.
• The region's advantage is not limited to vehicle volume. Chinese automakers operate short product cycles and aggressive cost-down programs that reward reduction in housings, harnesses, connectors and external controllers. Local silicon carbide, inverter, motor and charging-electronics supply chains also allow closer co-development. Japan and South Korea contribute semiconductor, motor and power-electronics expertise. Their OEMs have generally adopted deeper multi-function integration more gradually.
• India is an emerging opportunity as EV localization expands. The near-term market remains centered on simpler 3-in-1 e-axles and separately packaged charging electronics. As domestic passenger EV volumes rise, multi-in-1 architectures could become attractive for compact vehicles where packaging efficiency and bill-of-material reduction are especially valuable.
• Recent developments confirm accelerating market activity. In April 2026, Valeo confirmed ahead of Auto China 2026 that its 5-in-1 Deep Integration power-electronics module had reached start of production in early 2026. In March 2026, Leapmotor debuted the A10, known globally as the B03X, using a 7-in-1 oil-cooled electric drive on its new A-platform. In March 2026, Geely highlighted the 11-in-1 electric drive in the EX2 after the model reached 465,775 sales during 2025. In January 2026, Geely reported 1.69 million new-energy vehicle sales in 2025 and set a 2026 NEV sales target of 2.22 million. This expands the addressable production base for its highly integrated drive architectures. In November 2025, Geely announced that the EX5, which uses its 11-in-1 electric drive system, had exceeded 210,000 global deliveries. In July 2025, Valeo announced that a major Chinese NEV manufacturer had selected its 5-in-1 module, with production scheduled for 2026.

Conclusion

• The global EV multi-in-1 integrated drive units market is growing steadily as OEMs pursue cost, weight and packaging efficiency. Growth is driven by hardware consolidation, software and control integration, and rapid commercialization in China. Five-function and higher architectures are moving from Chinese premium platforms into broader mass-market EV programs. Global Tier 1 suppliers are adapting multi-in-1 platforms for international OEMs. Thermal coupling and repairability remain the key restraints. Shared semiconductors, integrated charging, 800 V silicon carbide platforms and domain-control fusion are shaping the technology direction. The market is projected to grow from USD 2.40 billion in 2026 to USD 5.80 billion by 2031 at a CAGR of 19.3%.
