Multi-in-one Electric Drive Technology Reconstructs the Core Battlefield of Electric Vehicles: Industrial Changes Under the Integration Revolution
In the arena of the electric vehicle industry, an “integration revolution” triggered by multi-in-one electric drive technology is rewriting industry rules. According to data from authoritative institutions, the installation penetration rate of multi-in-one electric drive systems reached 14% in the first three months of 2025, with ultra-integrated systems such as 11-in-1 and 12-in-1 accounting for over 36%. This technological transformation has not only reshaped the physical form of power systems but also opened up new battlefields in the A0-segment and A-segment vehicle markets.
Currently, 80% of multi-in-one system installations are concentrated in A0-segment and A-segment models, a phenomenon that reveals the deep logic of industrial development. Take BYD as an example: its eight-in-one system has established a technical matrix covering A0 to B-segment models, demonstrating unique advantages in cost control and performance balance. Geely, with its eleven-in-one system, has captured a 46% installation share in the A0-segment market, 印证 (confirming) the feasibility of the “small vehicle, large integration” technical route. Notably, the 18% installation proportion in the B-segment market indicates that high-end models are increasingly accepting integration technologies.
In this integration race, independent automakers have demonstrated astonishing technological 爆发力. BYD’s “three-dimensional integration” solution deeply integrates hardware, software, and thermal management, pushing system efficiency beyond the 95% threshold; Geely’s 12-in-1 system has achieved deep coupling of BMS (Battery Management System) and VCU (Vehicle Control Unit). In contrast, among traditional suppliers, except for Injoinic, most companies’ 7-10-in-1 solutions remain in the laboratory stage. This gap reflects a profound transformation in the industrial landscape: automakers with full-stack self-developed capabilities are redefining technical standards through the “vehicle-defined electric drive” model.
Current technological evolution faces three core contradictions: First, the conflict between increased integration and heat dissipation efficiency, as thermal management difficulties for highly integrated systems grow exponentially; second, the contradiction between large-scale mass production and customized demands; third, the balance between cost control and technological deepening—according to estimates, each additional integrated unit increases R&D costs by approximately 8%. These challenges have accelerated the application of 800V high-voltage platforms and silicon carbide devices. It is expected that by 2026, high-voltage platform models will drive a 20% cost reduction in multi-in-one systems.
In this quiet technological revolution, the industry is facing a critical turning point. As an important participant in the integration wave, Zhengheng Power combines precision casting and flexible intelligent manufacturing capabilities. Through the deep coupling of material process innovation and intelligent production systems, it provides personalized support for customers’ multi-in-one electric drive systems: from design to various casting processes (gravity/low-pressure/high-pressure multi-production line collaboration), and then to the vertical integration of precision machining systems, it can accurately adapt to the differentiated needs of electric drive systems with different integration levels for structural strength, heat dissipation efficiency, and lightweighting.
In the next three years, with breakthroughs in material innovation and intelligent control technologies, multi-in-one electric drives may give birth to new species such as “evolvable power systems.” The industrial transformation triggered by integration has just begun.
