From decentralization to integration: Intelligent controllers (PDU/VCU) lead the transformation of new energy and electrification
Jul. 14, 2026
With the rapid development of new energy vehicles, electric engineering machinery and energy storage fields, as the "brain" and "heart"Intelligent controller (PDU/VCU)It is undergoing a technological transition from functional overlay to deep integration. In 2026, industry competition has shifted from performance competition of single components toAll-in-one integrated power domain controllercomprehensive contest.
Traditional electric vehicle electronic control systems mostly adopt a distributed architecture: the vehicle controller (VCU), high-voltage power distribution unit (PDU), battery management system (BMS) and motor controller (MCU) are independent and connected through complex wiring harnesses. This model not only increases the volume and cost, but also brings control delays and diagnostic difficulties.
current,All-in-one deep integration has become the industry mainstream. Take the nine-in-one integrated power domain controller recently released by Great Wall Heavy Industries as an example. This product highly integrates nine core modules such as main drive motor controller, VCU, PDU and dual-channel DCDC. passChip-level convergence design, achieving significant effects of reducing system weight by 10%, volume by 15%, and connection points by 39%. Under harsh working conditions such as mines, the reliability has increased by 65%, and the average time between failures has exceeded 10,000 hours, marking the leap of intelligent controllers from "usable" to "durable and easy to use".
The integration of intelligent controllers is essentially to meet the increasingly complex needs of software-defined automobiles. Market data shows that the global vehicle control unit (VCU) market size has reached US$10.4 billion in 2024, and is expected to grow to US$20.7 billion by 2034, with a compound annual growth rate of 7.8%.Domain Controller (PDCU)With the rise of the automobile industry, the deep integration of engine, gearbox and vehicle control functions has become a key path for OEMs to reduce costs and increase efficiency.
In addition, PDU (power distribution unit) shows "dual growth" in the fields of new energy vehicles and data centers. On the electric vehicle side, the popularization of 800-volt high-voltage platforms has put forward higher requirements for the arc suppression and insulation withstand voltage of PDU, pushing it towardsSolid-state switches and intelligent topology reconstructionEvolution; on the data center side, as the demand for AI computing power explodes, the smart power distribution unit (PDU) market is expected to reach US$726 million in 2032, with a compound annual growth rate of 11%.
This technological change is attracting an influx of capital and cross-border players. Recently, Fengzhirulian, which specializes in intelligent power domain controllers (i-PDCU), completed tens of millions of yuan in Series A financing. Its products integrate VCU, BMS and MCU, aiming to improve the intelligence level of the entire vehicle. At the same time, Suyu Technology has launched a programmable integrated electronic control architecture in the field of hydrogen and new energy. At the hardware level, it integrates core modules such as FCU, DCU, and PDU. Through the high integration of software and hardware, it achieves an efficiency breakthrough that reduces equipment costs by 20% and labor costs by 80%.
Traditional automotive electronics giants are also accelerating their layout. Both United Electronics and Vitesco Technology demonstrated all-in-one electric drive system solutions covering platforms from 400 volts to 800 volts, deeply integrating OBC, DCDC, PDU and VCU into electric bridge products to achieve dual improvements in power density and system efficiency.
As intelligent controllers (PDU/VCU) move from "functional integration" to "chip deep integration", the "brains" of electric vehicles and intelligent equipment are becoming more concentrated and smarter. This trend not only reconstructs the supply chain value system, but also brings more reliable, efficient and sustainable iterative travel and work experience to end users.
