Shenzhen Kehua’s high-efficiency 40kW SiC charging module, renowned for its outstanding technical performance and rigorous standards, has successfully obtained international certifications, including CE, CB and UL.
These certifications ensure compliance with key market standards across Europe, North America, South America, Asia, and Oceania, enabling large-scale global deployment.
For charging station manufacturers, this translates into greater flexibility in power module sourcing, simplified selection processes, and significantly shorter product development cycles.
Companies no longer need separate charging modules for each market, reducing development complexity, financial costs, and improving capital flow efficiency.
What are the advantages of Kehua’s 40kW SiC Power Module?
1. Exceptional “Three Highs”
High Efficiency
The Kehua’s 40kW SiC Module 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
The 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 Kehua’s 40kW SiC 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
Kehua’s 40kW SiC 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 three 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.
Shenzhen Kehua’s 40kW high-efficiency SiC power module delivers reliable, high-performance core components for charging station manufacturers.
