Precision engineered parts designed to exceed OEM performance specifications across thermal, propulsion, and structural systems.
The global transition toward electrification demands more than just replacing combustion engines with electric motors. Modern Electric Vehicles (EVs) require an entirely new ecosystem of precision-engineered components capable of managing high-power currents, complex thermal dynamics, and autonomous sensor arrays. As global standards tighten (e.g., Euro 7 regulations and severe EPA limits), OEMs face the intense pressure of sourcing parts that are lighter, highly efficient, and exceptionally reliable over long lifespans.
At Guangzhou Yihe Auto Co., Ltd., we operate as a specialized global Custom OEM EV Components Supplier & Exporter. With a state-of-the-art facility in Guangzhou, China, we produce and source crucial sub-systems including high-performance liquid cooling plates, advanced LED optical chips for ADAS and driver-assistance systems, ruggedized truck transmission parts, and structural castings optimized for commercial electric vehicles. We serve Tier-1 systems integrators, commercial fleet operators, and global distributors demanding robust mechanical integrity and advanced electrical performance.
"True innovation in the EV supply chain lies in micro-efficiencies. Developing thermal plates with optimized coolant channel layouts directly improves battery pack health by up to 22%, which mitigates cell degradation and optimizes fast-charging capabilities."
No two markets run EVs in the exact same manner. Different geographies pose distinct stresses on EV powertrains and structural casings. Realizing maximum performance demands application-specific optimizations that we provide as an experienced OEM/ODM provider:

Guangzhou is one of China’s preeminent automotive hubs, housing massive supply chains, high-level metallurgical laboratories, and world-class shipping ports (Guangzhou Port/Nansha Port). Operating in this rich industrial cluster allows Guangzhou Yihe Auto Co., Ltd. to secure raw materials (automotive-grade aluminum alloys, semiconductors, optical LED components) at unmatched speed and competitive pricing.
Our production facilities utilize state-of-the-art horizontal machining centers (HMCs), 5-axis CNC routers, and high-pressure cold-chamber die casting machines (ranging from 500 to 2500 tons). We also implement advanced welding techniques such as Friction Stir Welding (FSW)—the gold standard for battery cooling plates to guarantee leak-free containment over millions of thermal expansion cycles. Every batch undergoes rigorous Helium leakage testing and coordinate measuring machine (CMM) dimensional validation.
The automotive landscape is rapidly transitioning to 800V electrical architectures (Silicon Carbide - SiC technology). 800V platforms enable ultra-fast charging but subject components to higher electric currents and elevated operating temperatures. As an advanced supplier, our technological roadmap encompasses:
Operating globally requires stringent compliance. We assist foreign buyers with localized logistics and legal adherence, ensuring smooth port entry.
Our facilities operate strictly under the IATF 16949:2016 quality management system, the gold standard for global automotive supply chains. Our electrical components meet CE, RoHS, and REACH criteria, ensuring zero importation bottlenecks into the European Union and North America.
Clear answers to common questions about engineering, manufacturing processes, and exporting logistics.
For custom battery cooling plate configurations, typical initial prototyping takes 3 to 4 weeks (including FEA thermal simulations, design iterations, CNC tooling adjustments, and leak tests). Once the prototype is approved, serial tooling production requires approximately 4 to 6 weeks, depending on design complexity.
We implement multiple validation layers. First, we employ Friction Stir Welding (FSW) to ensure micro-welding strength. Second, we execute high-pressure air and helium vacuum leak testing on 100% of finished cooling plates. Third, thermal cycle testing (-40°C to 120°C) is conducted to simulate field conditions.
Yes, our flexible engineering team can execute custom retrofits and low-volume production (low MOQ options) for specialized electric mining vehicles, heavy-duty commercial fleets, and prototype builds, alongside our high-volume serial assembly lines.
We provide comprehensive export documentation, including Certificate of Origin, compliance declarations (RoHS/REACH), commercial invoices, packing lists, and bill of lading. Our experienced export department manages ocean freight booking, air express shipping, and works with customs brokers to ensure timely, hassle-free port clearance.
