Suntrans™ Intelligent charging system based on flexible intelligent distribution technology not only effectively solves the problem of adding new charging piles due to the limitation of dedicated substations and insufficient power capacity, but also optimizes the allocation of existing power resources through intelligent integrated energy management and scheduling.This means that "shared power" is to quickly build a large-scale layout of charging piles without the need for power capacity, which is of great significance.

Convenience is another key to improving the user experience.Suntrans™ Smart AC charging pile supports seamless connection with SuntransPlat cloud energy management and control platform, users can easily find the nearest idle charging pile through the mobile app, and complete the charging process monitoring, recharge payment and other operations.This one-stop service greatly improves the convenience of charging for users and lowers the threshold for the use of new energy vehicle owners.
Intelligence is the inevitable trend of the future development of charging infrastructure.The intelligent scheduling function of Suntrans™ intelligent AC charging pile not only realizes efficient coordination with the regional power grid, but also provides accurate decision-making basis for policy makers through big data analysis.In terms of hardware design, the highly integrated and modular design of the charging pile greatly simplifies the installation and maintenance work, while reducing the space occupation, making it easy to adapt to the layout requirements of various cities, parks and residential areas.
