I. Technical Breakthrough: A Tri-fold Innovation System

The ultra-high-power and high-efficiency flexible charging and discharging key technology features high-efficiency conversion, active support, and safety protection:

1. High-efficiency Energy Conversion: Based on the design of a three-port energy conversion and multi-segment bus architecture, it realizes optimal efficiency of new energy utilization, the coordinated dispatching of multiple energy sources, and the flexible interconnection and capacity expansion between photovoltaic and energy storage.

2. Active Grid Support: By integrating localized frequency control and grid-forming support technologies, it taps the potential of mobile energy storage and establishes an active support system featuring the rapid response of a new power system.

3. Battery Charging Safety Protection: Thanks to the multi-dimensional and multi-timescale battery risk diagnosis system with cloud-edge collaboration, it actively adjusts the charging strategy and improves battery safety protection ability.

II. Demonstration Effect: Setting Benchmark for "Zero Capacity Increase" Ultra-fast Charging Station

On the same day, iES Lab New Energy in collaboration with CAMS New Energy Technology Co., Ltd., held the opening ceremony of the first fully liquid-cooled flexible charging and discharging system demonstration station at Fuminda Science and Technology Innovation Center in Shenzhen. Zou Peng, Executive Secretary General of the Charging and Swapping Branch of China Association of Automobile Manufacturers and Electric Vehicle Charging Infrastructure Promotion Alliance, Zhou Xiantao, General Manager and CEO of CAMS New Energy Technology Co., Ltd., Ma Huajie, Deputy General Manager of iES Lab New Energy, and Shi Qi, General Manager of the South Region of CAMS New Energy Technology Co., Ltd. jointly witnessed the opening ceremony.

As a demonstration application of the ultra-high-power and high-efficiency flexible charging and discharging technology, this station is equipped with a complete photovoltaic-energy storage-charging-discharging integrated energy management system and a fully liquid-cooled flexible charging and discharging system. The power generated by photovoltaic is supplied to the charging station preferentially, and its excess energy is absorbed by the storage system, realizing diversified, intelligent, and efficient energy utilization.
