01 Scenario Tackling: Addressing Time-sensitive Pain Points and Enhancing Charging Efficiency

Electric heavy-duty trucks bear a significant responsibility for cargo transportation, demanding extremely high timeliness in transportation. In response to the high-frequency, heavy-load, and all-weather operational characteristics of heavy-duty logistics trunk lines, Nanjing Nengrui has deployed a high-power fast-charging solution for the Xinfeng New Energy Charging Station, capable of simultaneously refueling 16 heavy-duty trucks. The core equipment of this station is the 400kW high-power DC dual-gun charging pile independently developed by Nanjing Nengrui. This product is compatible with a wide voltage range from 200-1000V, offering a wider range of vehicle compatibility. Each pile is equipped with dual guns and innovatively incorporates an efficient charging module capable of supporting dual-gun parallel charging at an ultra-high current of 500A. Vehicles can be fully charged and ready to depart in an average of one hour, achieving an efficiency improvement of over 50% compared to traditional charging modes and significantly reducing charging waiting times. Furthermore, the triple high-reliability design effectively reduces heat generation from the charging guns, enhances charging reliability, and ensures operational timeliness.

"Good products are the backbone of efficient operation of charging stations," said the person in charge of operations at Xinfeng Charging Station. "As a carefully selected brand by the State Grid, the heavy-duty truck charging pile equipment deployed by Nanjing Nengrui not only charges quickly and has a low failure rate, but also operates very stably in dusty and high-temperature environments. This allows truck drivers to rest and recharge their vehicles quickly and reliably while they are in the station's rest area, which also effectively reduces our operational management pressure."

02 Digital Empowerment: Intelligent Platform Drives Efficient Operations

To ensure the continuous and reliable operation of heavy-duty truck charging piles and enhance operation and maintenance (O&M) efficiency, Nanjing Nengrui has developed a comprehensive charging operation management platform that integrates intelligent monitoring, data analysis, remote control, and efficient O&M. This platform provides full lifecycle management for new energy vehicle charging stations. At the Xinfeng New Energy Charging Station, this platform plays a core management role: by collecting real-time operational data from the station's charging piles and combining it with AI algorithms, it achieves load forecasting, dynamic scheduling, and fault warning. For example, during peak traffic periods, the platform intelligently allocates power resources and optimizes the charging queue, effectively avoiding congestion. Additionally, the platform supports interconnection and interoperability among multiple operators and payment channels, and provides a user-end app and an operational backend. This helps Xinfeng station efficiently manage the daily charging needs of heavy-duty trucks, optimize network layout, enhance operational efficiency, and reduce maintenance costs.

03 Full-cycle operation and maintenance: Building a reliable support system

With the rapid development of the electric heavy-duty truck market, the surge in charging demand has given rise to a vast energy replenishment market. However, operators generally face the challenges of "easy site construction, difficult operation and maintenance, and difficult profitability". To this end, Nanjing Nengrui provides full lifecycle empowerment for station owners, covering early-stage planning and site selection as well as power access design, mid-stage intelligent charging facility construction and digital operation platform establishment, later-stage energy management optimization, and long-term operational support. Through technological innovation and ecosystem integration, Jinguan shares helps stations reduce investment and operational costs, improve charging efficiency, power dispatch flexibility, and comprehensive revenue, while supporting the continuous upgrading of business models. Ultimately, it achieves cost reduction and efficiency improvement across the entire new energy station chain, green and low-carbon operations, and maximization of long-term value.

Currently, Nanjing Nengrui's heavy-duty truck charging network has covered logistics hubs in multiple provinces across the country, and has accumulated successful application experience in extreme scenarios such as mines, logistics parks, and ports, fully verifying the all-weather adaptability of the solution. In the future, Nanjing Nengrui will continue to deepen technological innovation and industrial ecosystem integration, break through the bottleneck of heavy-duty truck electrification application, provide a full-chain solution from technology research and development, infrastructure to scenario operation, and fully support the green logistics transformation under the strategy of building a strong transportation country.
