EV charging is on the fast track, and Shenzhen Kehua, a leader in power electronics, is accelerating the journey with their innovative 40kW silicon carbide (SiC) charging module. Designed to tackle key challenges like efficiency, noise reduction, and wider operating temperatures, this next-generation module promises a smoother, more reliable charging experience for EV users.
Charging Efficiency Gets a Boost
The heart of Kehua’s solution lies in its use of SiC technology. This innovative material allows the module to achieve a remarkable full load efficiency of ≥96% and a peak efficiency of ≥97%. Compared to traditional silicon (Si) designs, this translates to a 1% efficiency improvement, a significant jump that saves energy and reduces costs. For charging station operators, this can translate to a substantial annual electricity cost saving – roughly €18,400 over five years for a 400kW charging station.
Peace and Quiet: A Quieter Charging Experience
Nobody enjoys the loud hum of a charging station. Kehua’s module addresses this concern with intelligent noise reduction technology. Employing a four-dimensional fan speed control system, it adjusts noise levels based on various factors like temperature and output current. This ensures the module operates quietly, with noise levels kept below 65dB(A) at full load and 25°C. Users can even choose from three silent mode levels to further reduce noise depending on the environment.
Built to Endure: Performance in Any Climate
From the frigid winters of Scandinavia to the scorching heat of the Middle East, Kehua’s charging module is built to perform. Its impressive operating temperature range spans from -40℃ to 75℃. Even in extreme cold, the module can deliver full power without additional heaters. This ensures reliable charging performance regardless of the climate.
Smoother Charging, Longer Battery Life
The module boasts ultra-low output current ripple, minimizing fluctuations in power delivery. This translates to a smoother charging experience for EVs and contributes to extending battery life by reducing cell heating.
