The Electric Compressor Controller (ECC) is the core control unit of the air conditioning and thermal management system of new energy vehicles. It is responsible for precise driving and regulation of the electric compressor and is suitable for electric vehicles, commercial vehicles, logistics vehicles and industrial cooling systems. Shouzhi Technology's electric compressor controller platform is based on advanced software and hardware technology, vertically expanding the two voltage platforms of 400V and 800V, providing single cooling, heat pump, two-in-one integration with PTC, and three-in-one integration (including PTC body) series of products. The product speed range covers 0 - 15000 rpm. It adopts 8k control frequency, 16K chopping frequency is controlled to 100 rpm, and speed fluctuations are controlled within 20 rpm. It adopts 12k control frequency, and 24K chopping frequency is stable to 15000 rpm. The speed fluctuations are controlled within 30 rpm. The working temperature covers-40 ℃-125 ℃. Through neural network learning algorithms, we can further improve control accuracy, improve voltage utilization, and develop a new generation of AI smart products to provide customers with more efficient and intelligent solutions.
