September 18–20, 2026, the 10th China Symposium on EV Charging, Battery Swapping and Drive Systems was successfully held in Jinan, the City of Springs. Aligned with the accelerated development of the new power system and the deep integration of transportation and energy, the conference carried out in-depth discussions on core topics including large-scale V2G deployment, high-power charging for heavy-duty trucks, battery safety & protection, and innovations in charging/swapping equipment and drive systems. It showcased the latest domestic research achievements and engineering practices in charging and battery swapping. As the main organizer of the event, Jicheng Zhitong joined industry experts and peers to explore paths for technological innovation and jointly plan the industrial implementation roadmap.
Focus on Transportation-Energy Integration to Solve Pain Points in the Power Refueling Industry
At the conference, Wang Lin, General Manager of the company, attended and delivered a keynote speech titled Practice of a New Transportation-Energy Integration Paradigm for Heavy-Duty Truck Charging and V2G. He stated that China’s new energy vehicle industry has completed large-scale expansion and officially entered a new phase of high-quality development. The focus of charging and battery swapping infrastructure construction is shifting from scale expansion to efficiency improvement.
With the continuous emergence of new technologies and models such as heavy-duty truck megawatt ultra-fast charging, vehicle-to-grid, integrated PV-storage-charge-discharge and virtual power plants, application scenarios including charging and swapping at ports and mining areas, and zero-carbon highway transportation-energy integration are being rolled out at an accelerated pace. The research directions of this symposium are directly related to the safe and efficient operation of charging stations, grid-source coordinated regulation and overall industrial upgrading. Multi-party collaborative research between industry, universities and research institutes is urgently needed to achieve joint breakthroughs.
To address common industry pain points including low refueling efficiency, difficult grid connection, poor scene adaptability and long investment payback periods, Jicheng Zhitong has launched an all-in-one charging solution featuring "Technology + Platform + Ecosystem".
Deepen technological innovation to build solid industrial support
In heavy-duty truck energy replenishment, the megawatt-level flexible group-controlled charging system covers power ranging from 240kW to 4.8MW. Adopting a dynamic power pool architecture, it delivers over 1MW output per gun. Equipped with 108 active protection mechanisms, it enables in-depth interaction with vehicle BMS and supports AI self-diagnosis and OTA remote maintenance.
The high-power integrated DC charger reaches a maximum power of 640kW. The four-gun DC charger achieves up to 800kW charging power, compatible with the wide voltage platform of DC200–1000V. Its weighted system efficiency ≥96.5%, supporting simultaneous charging of 2, 3 or 4 guns.
The medium-voltage direct-connected PV-storage-charging solution adopts 10kV medium-voltage direct step-down, phase-shifting transformer and multi-pulse rectification technologies. The power loss of the whole station is reduced by more than 40%, the total harmonic distortion is controlled within 3%, and the local consumption rate of green power can reach 60%–80%.
The megawatt-level full-liquid-cooled flexible charge-discharge system has a total rated power of 2MW and supports output via 18 charging cables. The single-gun liquid-cooled terminal delivers a maximum power of 1.2MW, featuring bidirectional DC metering and V2G vehicle-to-grid capability. The integrated V2G charge-discharge equipment adopts a modular integrated design with peak conversion efficiency exceeding 97%. It achieves deep coordination with vehicle BMS to ensure safe and controllable charging and discharging throughout the whole process.
The IE Charging Operation Platform and New Energy Microgrid Control System enable unified access and management of charging piles, PV and energy storage systems. It supports dynamic power pool dispatching, intelligent peak-valley strategies, remote maintenance and multi-station aggregated regulation. Compliant with 104 protocol at station side, it can interact with the superior grid dispatching platform, strongly supporting the implementation of virtual power plant and demand response services.
Showcase innovative achievements, jointly write a new chapter of transportation-energy integration
During the conference, the booth of Jicheng Zhitong attracted many participating experts and industry representatives to stop by for observation and in-depth exchanges. The company showcased a series of products and solutions covering heavy-duty high-power charging, V2G system integration, and coordinated PV-storage-charging, fully demonstrating the company’s profound technical reserves and innovation strength in charging & battery swapping and V2G sectors.
Gather Strength from Industry, University and Research Institutes, Empower Energy and Transportation Development
The successful holding of this symposium brings together top industry insights and builds a high-level industry-university-research exchange platform in the field of charging, battery swapping and drive systems. It injects strong momentum into industrial technological breakthroughs, achievement transformation and industrial upgrading. As the vice-chairman unit of the special committee, Jicheng Zhitong will continue to focus on the core tracks of heavy-duty truck ultra-fast charging and vehicle-to-grid interaction. We will cooperate with industry peers to deepen technical discussions and promote practical cooperation, continuously empowering the green and low-carbon transformation of transportation, and making solid contributions to the construction of new power systems and the high-quality integrated development of energy and transportation.
