en.Wedoany.com Reported - The Juneng Heavy-Duty Truck Solar-Storage Charging Station, put into operation by China's Yuanhe Energy on North Ring Road in Yanzhou, Jining City, Shandong Province, provides 24-hour affordable charging services. The station adopts a three-in-one model of "photovoltaic + energy storage + supercharging," offering a full-chain green solution for urban transportation and industrial/commercial energy replenishment scenarios.
As a National High-Tech Enterprise and a Beijing "Specialized, Refined, Distinctive, and Innovative" SME, the Yuanhe Energy team has infused 15 years of power electronics and energy storage system expertise into the construction of the Juneng Charging Station. The station is equipped with a self-developed C20 fully liquid-cooled energy storage system, compatible with both 1000VDC and 1500VDC dual voltage platforms. Coupled with the Yuanhe Qianyuan digital energy management platform, it achieves cell-level refined monitoring and millisecond-level intelligent scheduling. The photovoltaic carport and energy storage system are directly connected to the DC bus of the charging stack, achieving an energy conversion efficiency of over 95%. The peak power per charging gun can reach 480kW, enabling an 80% energy replenishment in just 30 minutes.
This project integrates dual technologies of S-grid (Strengthened Grid) and F-grid (Flexible Interconnection), supporting the simultaneous operation of 24 charging parking spaces (including 10 fast-charging spaces for heavy-duty trucks) without requiring large-scale grid upgrades. By using energy storage for peak shaving and valley filling to smooth load fluctuations, it effectively reduces pressure on transformers, making it suitable for high-power energy replenishment scenarios such as highway service areas, industrial parks, and logistics hubs.
In terms of economic efficiency, relying on the model of "PV self-generation and self-consumption + energy storage peak-valley arbitrage," the charging station converts solar energy into clean electricity during the day, prioritizing supply for charging, and stores surplus electricity for release during peak hours, which can reduce operational electricity costs by 30%-50%. The energy storage system also needs to recharge during midday deep valley and valley electricity price periods, thus enabling the solar-storage-charging flexible charging piles to achieve affordable pricing all day long, even during peak and critical peak grid electricity price periods.
In terms of green and low-carbon operation, the photovoltaic system generates over 600,000 kWh annually. Combined with the energy storage system's 100% consumption of clean energy, it can reduce carbon dioxide emissions by over 348.6 tons per year and save approximately 192 tons of standard coal, equivalent to planting over 17,430 mature trees. The zero-emission full chain from power generation to energy replenishment makes every charging session a concrete action towards achieving the dual carbon goals.
In terms of safety, the charging station has established a triple safety defense line of "multi-layered fire protection + intelligent early warning + 24-hour on-duty personnel." The eMetaCube energy storage system features a design with distributed fire protection, physical compartment isolation, and electrical safety isolation. Edge AI intelligent controllers monitor key indicators such as temperature and smoke in real-time. This, combined with strict safety production regulations and emergency response plans, ensures stable power supply even during extreme weather, grid fluctuations, or sudden failures.
Under the guidance of policies such as China's National "New Energy Vehicle Industry Development Plan (2021-2035)" and the "Notice on Promoting the Scientific Planning and Construction of High-Power Charging Facilities," solar-storage-charging integration has become a core carrier for the integration of new power systems and green transportation. The Yuanhe Energy Juneng Charging Station has established an energy closed loop of "self-generation and self-consumption, surplus electricity storage, intelligent scheduling, and safety controllability." From technological innovation to scenario implementation, from cost optimization to ecosystem co-construction, the Yuanhe Energy Yanbei Juneng Solar-Storage Heavy-Duty Truck Charging Station, guided by the core philosophy of "making electricity cleaner and energy smarter," is setting a replicable and scalable benchmark model for the new energy replenishment industry.
The Yuanhe Energy Yanbei Juneng Solar-Storage Heavy-Duty Truck Charging Station—more than just a charging station, it is a flexible node in the city's smart energy network, the power core of green transportation, and a future force of electricity serving the power grid.
