Shenzhen Kehua’s 40 kW High-Efficiency SiC Charging Module Achieves CE, CB, and UL Certifications

 

With the rapid development of the global electric vehicle industry, the reliability, efficiency, and intelligence of charging infrastructure have become core industry concerns. Shenzhen Kehua’s 40kW high-efficiency SiC charging module, with its outstanding technical performance and rigorous standards, has successfully obtained international certifications including CE, CB, and UL.

These certifications ensure compliance with major market standards in Europe, North America, South America, Asia, and Oceania, enabling broad global deployment. For charging station manufacturers, this means greater flexibility in power module procurement, simplified selection processes, and significantly shorter product development cycles. Companies no longer need different charging modules for each market, reducing development complexity and financial burden, while improving capital turnover efficiency.

Advantages of Shenzhen Kehua 40kW SiC Power Module

1. Exceptional “Three Highs”

High Efficiency

The 40kW SiC power module features an advanced full-bridge LLC interleaved soft-switching topology and high-voltage, low-on-resistance SiC components, maximizing power conversion efficiency. With a peak efficiency of up to 97%, each 1% improvement over 96% can save approximately 350 kWh of electricity per power module annually, assuming a station utilization rate of 10%. This high-efficiency design not only enhances energy conversion but also significantly boosts operational revenue.

High Safety

Safety is critical for charging equipment. The 40kW SiC charging module features over 60 protection functions, including overvoltage, undervoltage, overtemperature, overcurrent, and short-circuit protection, ensuring stable operation even in complex environments. It complies with the latest IEC 61851-23:2023 and UL2202 standards and includes a module-in-position detection feature, effectively preventing arcing caused by poor contact and ensuring safe operation from the source.

High Protection Level

The power module employs automotive-grade potting technology, significantly enhancing water, dust, and corrosion resistance. It operates reliably in humid, high-salt, or high-dust environments, making it suitable for urban charging stations as well as harsh locations like mines, meeting diverse operational demands.

2. Outstanding “Three Lows”

Low Failure Rate

Thanks to high-quality components, reliable design, automotive-grade manufacturing, and an intelligent tracking management system, the 40kW SiC power module has a very low failure rate. Its mean time between failures reaches 300,000 hours at 25°C, ensuring long-term stability and reliability.

Low Noise

The use of SiC components and full-bridge LLC soft-switching topology not only improves charging efficiency but also reduces internal heat and fan noise. Equipped with stepless-speed fans and a four-dimensional intelligent control algorithm, the charging module provides three silent modes (65 dB, 60 dB, 55 dB), ideal for noise-sensitive environments such as residential areas and commercial complexes.

Low Interference

The charging module meets EMC Class B standards, with conducted and radiated emissions at residential levels, offering low interference and strong anti-disturbance capabilities. In a complete charging station design, no additional filters are required, reducing design costs, streamlining certification, and significantly shortening time-to-market.

3. Exceptional “Three Easies”

Easy Installation

The modular design allows for quick and simple installation, improving deployment efficiency, shortening installation time, reducing labor costs, and enabling rapid station operation.

Easy Operation

Equipped with an Nixie tube, the charging module displays real-time output voltage, current, module address, group number, and fault codes. This intuitive display allows operators to quickly monitor status, adjust settings, and perform maintenance, enhancing the user experience.

Easy Maintenance

With hot-swappable functionality and fault indicators,power modules can be replaced without shutting down the station. Faults are indicated with red lights and codes, and the average repair time (MTTR) is only 3 minutes, ensuring continuous operation.

4. Strong “Three Capabilities”

Versatility

The power module supports a wide output voltage range of 150–1000Vdc, suitable for passenger cars, buses, and heavy-duty trucks. Its operating temperature range of -40°C to 75°C allows stable operation in extreme climates worldwide, from the heat of the Middle East to the cold of Northern Europe.

Intelligence

The intelligent control system adjusts voltage and current in real-time according to vehicle requirements, with fast and precise regulation and real-time data reporting. DSP digital control and advanced PLL phase-locked loop algorithms provide strong adaptability to complex and weak grid environments, ensuring safe and stable charging.

Universality

Featuring a universal interface design, the power module is highly compatible with different charging stations, simplifying system integration. Standardized dimensions and protocols reduce development and deployment costs while ensuring broad applicability across various systems.
