Observations from the 2026 Munich Shanghai Electronics Show: Growing demand for automotive electronics and new energy, high-power charging brings new testing needs

In September 2026, the Munich Shanghai Electronics Expo officially opened, and the automotive electronics and new energy charging industry chain became one of the most focused core exhibition areas of this session. Judging from the layout of exhibits, technology releases, and industry feedback from companies on site, with the continuous rise of domestic new energy vehicle ownership and the accelerated implementation of high-power supercharging networks, the output power per charging port is rapidly evolving to over 300kW, and bidirectional programmable DC power supplies have already become widely recognized as essential testing equipment across the industry chain.

At this expo, multiple electronic component and charging equipment manufacturers from Shenzhen, Guangdong, Jiangsu, and other regions concentrated on showcasing core components and complete solutions suitable for high-power new energy vehicle charging scenarios. Companies like Shenzhen Redchip Technology and Shenzhen Jilexin Technology Development brought automotive-grade power management chips and power semiconductor devices, clearly marked as suitable for high-voltage fast-charging scenarios under 24+ conditions, supporting the long-term stable operation of DC charging piles above 300kW. Exhibitors generally reported that in 2026, orders for downstream charging stations include a year-on-year increase of over 60% for heavy-duty supercharging piles of 480kW, 640kW, or even higher, while traditional 200kW and below charging piles can no longer meet the energy replenishment needs of current 800V high-voltage platform models and new energy heavy-duty trucks.

Changes in real-world industry applications directly drive upgrades in testing standards. By July 2026, the domestic fleet of new energy heavy trucks had surpassed 700,000, but the construction of matching high-power charging stations has consistently lagged behind vehicle growth. Many operators in mines, ports, and logistics parks frequently encountered issues such as module damage, overheating of charging guns, and power mislabeling after purchasing equipment, with some projects experiencing operational anomalies within three months of deployment, directly reducing fleet turnover efficiency. One key reason for this problem is that small and medium-sized manufacturers commonly used simple testing equipment that could not simulate power fluctuations, grid impacts, and battery feedback under full operating conditions, leading to a serious gap between performance indicators at the factory and actual outdoor performance.

With the official rollout of the CCC mandatory certification for charging piles on August 1, 2026, testing requirements across the industry have been rigorously raised. The new regulations require all DC charging piles used in commercial scenarios to pass tests covering dozens of safety indicators, including electric shock protection, short-circuit overload and flame resistance, high and low temperature adaptability, and insulation reliability. Additionally, the manufacturing plant's quality management system and full-process quality control standards also need to pass on-site audits. Against this backdrop, bidirectional programmable DC power supplies have become essential equipment for the R&D, pilot production, and factory testing of high-power charging piles over 300kW: they not only accurately simulate vehicle-end voltage feedback across the 200V-1000V range but also reproduce complex conditions such as grid peak-valley fluctuations, extreme low temperatures, and sudden load changes. This helps manufacturers verify the stability of output when the equipment runs at full power continuously for over 2 hours, keeping actual output fluctuations within ±2%, which prevents the common issue at the testing stage where a charging pile labeled as 480kW only actually peaks at 350kW.

Data from industry exchanges at the exhibition show that the domestic charging pile market is currently at a critical point of structural upgrading. By 2026, the overall market size is expected to reach 169 billion yuan, with high-power fast charging, retrofitting of existing facilities, and overseas exports growing much faster than the industry average. Leading compliant manufacturers have already had their equipment tested in multiple long-term scenarios, while regional small and medium-sized manufacturers are speeding up to fill the gaps in their testing capabilities. White-label assembly factories, unable to meet the full set of testing requirements for 3C certification, are quickly exiting the market. Many charging equipment exhibitors said that after introducing bidirectional programmable DC power supplies as core testing equipment, the on-site failure rate of products after leaving the factory dropped by over 70%, and operating costs at charging stations were significantly controlled.  

Signals from this year’s Munich Shanghai Electronics Fair suggest that the competitive logic of the automotive electronics and new energy charging industry has completely shifted from 'competing on capacity and price' to 'competing on testing accuracy and full-scenario reliability.' With the full adoption of 800V high-voltage platform models and the market share of 5C ultra-fast charging vehicles steadily increasing, the market penetration of high-power charging piles above 300kW is expected to further rise. Corresponding high-precision testing equipment demand will continue to grow, becoming a key foundational element supporting the high-quality upgrade of the entire charging infrastructure industry.
