800V high-voltage platform technology is rapidly gaining popularity, with silicon carbide devices becoming key to improving the performance of new energy vehicles.
As the global new energy vehicle industry moves toward higher efficiency and intelligent technology, 800V high-voltage platform technology is becoming the new industry standard. As a core component of this technological revolution, silicon carbide (SiC) power devices, with their high-frequency, high-voltage, and high-temperature tolerance, are becoming a key driver for increasing electric vehicle range and reducing charging times. Xi'an Wanpu Import and Export Trading Co., Ltd. keeps pace with this technological trend and, by integrating upstream supply chain resources, provides global customers with high-performance SiC modules and supporting solutions, helping the new energy vehicle industry achieve leapfrog development.
[800V platform has significant advantages, SiC devices solve core pain points]
Traditional 400V voltage platforms are limited by cable thickness, weight, and thermal management challenges, making them unable to meet consumer demand for rapid charging and extended driving range. The 800V high-voltage platform can increase charging power to over 350kW, increasing driving range by 200 kilometers with a five-minute charge, while also reducing energy transmission losses by approximately 50%. SiC devices play a crucial role in this system. Their switching frequency can reach five times that of silicon-based IGBTs, and their temperature resistance exceeds 200°C. This boosts electric drive system efficiency to over 97%, increasing vehicle range by 5%-10%.
However, the cost of SiC devices has historically hindered their widespread adoption. By 2024, the price of domestically produced 6-inch SiC substrates had fallen by over 40% year-on-year, with module prices from major international manufacturers dropping to under 2,000 yuan. Domestic manufacturers have even introduced solutions priced under 1,500 yuan. This cost-reduction trend resonates with demand for the 800V platform. The global SiC device market is projected to exceed 40 billion yuan in 2028, with new energy vehicles accounting for over 70% of this market share.
[Diversified technical routes, hybrid solutions become a cost-reduction tool]
To balance performance and cost, the industry has explored multiple innovative approaches. In August 2025, Xpeng Motors and Xinlian Integrated Circuit jointly announced the mass production of China's first hybrid silicon carbide (Hybrid-SiC) product. By cleverly combining silicon-based IGBTs and SiC MOSFETs, this solution retains over 80% of SiC's performance advantages while keeping costs within 1.5 times that of traditional solutions. 10 This solution has been adopted by OEMs such as Geely, BYD, and Changan, and the penetration rate of hybrid SiC in electric drive systems is expected to reach 25% by 2026. 5
Meanwhile, Lantu Auto's "Lanhai Intelligent Hybrid Technology" utilizes a full-range 800V silicon carbide architecture, coupled with a 5C superCharger Battery, enabling a 20% to 80% charge in just 12 minutes, achieving a CLTC pure electric range exceeding 410 kilometers. 7 Its battery pack has passed extreme tests such as needle penetration and a 5-meter drop, demonstrating the reliability of SiC systems in safety-critical scenarios. 6
[China's supply chain rises, Wanpu helps global industry collaboration]
The maturity of the domestic SiC industry chain is providing strong impetus for technology adoption. Xinlian Integrated Circuit has built China's first 8-inch SiC MOSFET production line, with key performance comparable to international benchmarks. 3 Times Electric will deliver its first batch of automotive-grade SiC modules in the first half of 2025, breaking the monopoly of international giants such as Infineon and STMicroelectronics. 9 Local companies are further reducing costs by over 20% through vertical integration—from substrate growth and epitaxial processing to module packaging. 4
Xi'an Wanpu Import and Export Trading Co., Ltd. is deeply involved in this wave of change. Leveraging years of experience in supply chain management, it has established strategic partnerships with leading domestic SiC manufacturers, providing one-stop procurement services for overseas customers. The company's SiC power modules cover core applications such as main drive inverters, on-board chargers (OBCs), and DC-DC converters. All are AEC-Q101 automotive-grade certified and support a wide operating temperature range of -40°C to 175°C. Wanpu also offers customized cooling solutions and drive circuit design support based on customer needs, helping OEMs shorten their R&D cycles.
[Future Outlook: SiC Ecosystem Collaboration Enters a New Stage]
With improved 8-inch substrate yields and the implementation of new packaging processes, SiC device costs are expected to reach parity with silicon-based products by 2027. 8 Over the next three years, SiC technology will be deeply integrated with intelligent driving. For example, efficient SiC-based power management systems can provide more stable power distribution for lidar and high-computing chips. V2G (vehicle-to-grid) technology leverages SiC's bidirectional conversion capabilities to enable intelligent interaction between electric vehicles and the power grid. 7
Xi'an Wanpu Import & Export Trading Co., Ltd. will continue to focus on technological innovation, planning to launch its third-generation SiC modules supporting 1200V/800A in the fourth quarter of 2025. We will also simultaneously expand into emerging applications such as photovoltaics and energy storage. We sincerely invite global partners to explore the technological dividends of the 800V era and, with more competitive products and more agile supply chain services, help the new energy vehicle industry move towards an efficient and low-carbon future.
