ROHM launches high-performance intelligent high-side switch: boosting the progress of automotive electronics
Amidst the rapid transformation of the global automotive industry, advances in semiconductor technology are providing strong support for the development of new energy vehicles. On August 5, 2025, ROHM, a
world-renowned semiconductor manufacturer, announced the release of the “BV1HBxxx Series,” a high-performance intelligent high-side switch for Zone-ECUs. Designed for applications such as automotive lighting, door locks, and power windows, this series effectively protects systems from excessive power input. Compliant with the AEC-Q100 automotive standard, it meets the automotive industry’s stringent reliability requirements.
With the continuous development of electric vehicles and autonomous driving technology, automotive electronic control systems are becoming increasingly complex. ROHM’s high-side switches provide low on-resistance and high energy handling capabilities while also addressing the capacitive load driving limitations of traditional IPDs. This innovation will drive the electrification of automobiles, reduce reliance on mechanical fuses, and provide greater safety and reliability for future smart cars.
The rise of Chinese new energy vehicle brands: Dual advantages in technology and market
In the global new energy vehicle market, Chinese brands are rapidly rising through their technological innovation and market strategies. Huawei’s collaboration with the Wenjie M8, launching a pure electric version equipped with Huawei’s latest battery life extension technology, marks another major breakthrough for China in battery technology. With a starting price of 378,000 yuan and expected to officially launch this month, the Wenjie M8 has attracted significant consumer interest.
Meanwhile, BYD also performed well in new energy vehicle sales, with July sales reaching 344,296 units and cumulative sales from January to July reaching 2,490,250 units, a year-on-year increase of 27.35%. This data not only demonstrates BYD’s leading position in the market, but also reflects Chinese consumers’ recognition and support for new energy vehicles.
Li Auto and NIO are also actively expanding their presence. Li Auto opened 19 new stores in July, further enhancing its market coverage and service capabilities. NIO plans to hold a technical launch event for the all-new ES8 in late August, marking a further expansion into the premium electric SUV market. The rapid development of these brands demonstrates the competitiveness of Chinese new energy vehicles in the global market.
Battery Technology Innovation: Dongfeng Solid-State Batteries and BYD’s Intelligent Breakthrough
Regarding battery technology, Dongfeng Epai Technology Co., Ltd. announced that its solid-state batteries will be available for automotive applications in 2026, boasting an energy density of 350Wh/kg and a range exceeding 1,000 kilometers. This technology will provide consumers with extended range and enhanced safety, especially in extreme weather conditions. Dongfeng’s solid-state batteries can maintain over 70% of their range at -30°C.
BYD has also achieved new breakthroughs in intelligent technology, with its patented “a robot” capable of automatically charging and inflating vehicles, enhancing the intelligent experience. These technological innovations not only enhance the performance of new energy vehicles but also provide consumers with a more convenient user experience.
Global Consumer Choices and Future Outlook
The rise of China’s new energy vehicles is not only the result of technological innovation but also driven by market demand. With the continuous advancement of battery technology and the continued growth of Chinese brands, Chinese new energy vehicles are gradually becoming the preferred choice for consumers around the world. For consumers seeking a balance between environmental protection and economic efficiency, Chinese new energy vehicles undoubtedly offer a highly attractive option.
In future market competition, technological innovation will continue to be the core competitiveness of Chinese auto brands. Both ROHM’s high-performance intelligent high-side switches and Dongfeng’s solid-state batteries are important indicators of China’s emerging presence in the global new energy vehicle market. With the introduction of more innovative technologies, the future of China’s new energy vehicles will become even brighter, worthy of the attention and anticipation of global consumers.
