InfiMotion presented its expanded portfolio of high-voltage electric drive systems and intelligent mobility architectures at the Auto China 2026 trade fair, held in Beijing from April 24 to May 3. The showcased hardware targets the efficiency and integration requirements of future passenger and commercial electric vehicles across global markets.
900V Electric Drive Units
The exhibition highlighted a new generation of 900V high-performance Electric Drive Units (EDUs). The TP501 coaxial dual-drive unit utilizes a lightweight magnesium-aluminum housing manufactured through semi-solid die-casting technology, which reduces overall component weight by up to 30%. Alongside it, the P600 electric drive unit integrates Mini-Pin winding technology and 0.2 mm ultra-thin silicon steel sheets. This internal configuration allows the P600 to achieve a China Light-Duty Vehicle Test Cycle (CLTC) efficiency of up to 92.4% when operating at voltages exceeding 750V.
High-Speed Motors and Control Architectures
For motor integration, the company debuted a high-speed X-Pin electric motor engineered to reach rotational speeds of 18,500 rpm. The motor incorporates direct cooling for both the stator and rotor to sustain high power outputs, while a 25% reduction in end height enables a more compact mechanical design. To manage these powertrains, InfiMotion presented an integrated control architecture that unifies the Vehicle Control Unit (VCU), Powertrain Control Module (PCMU), and Battery Management System (BMS) into a single system. Additionally, the booth featured charging infrastructure solutions ranging from 7 kW residential setups to 1,920 kW liquid-cooled ultra-fast systems.

In the high-voltage EV powertrain sector, the transition from 400V to 800V and 900V architectures allows for reduced cable diameters and lower thermal losses. InfiMotion's use of a magnesium-aluminum alloy for the TP501 housing represents a critical materials engineering shift; magnesium is approximately 33% lighter than standard aluminum but historically challenging to die-cast for high-stress automotive structural components. Furthermore, the P600 unit achieves its compact footprint by utilizing coaxial planetary gearsets rather than traditional parallel-axis reducers. This enables a system weight of 77 kg while supporting torque outputs up to 5,200 Nm. This benchmarks directly against compact performance EDUs from Tier-1 suppliers such as BorgWarner and ZF, emphasizing power density metrics exceeding 4.8 kW/kg for premium vehicle applications.
