Against the backdrop of the dual-carbon strategy and the rapid development of the new energy transportation industry, the integration of distributed comprehensive energy and electric vehicle energy supplement scenarios has accelerated. Recently, Xinrui Energy has completed the full-link technical integration and scheme implementation of the integrated PV-storage-charging system and battery swapping comprehensive service platform. Through the in-depth coupling of five core modules including photovoltaic system, energy storage system, charging system, battery swapping system and intelligent energy management system (EMS), it builds an integrated closed-loop energy service system of "self-production - storage - fast charging - fast swapping - intelligent scheduling". The platform provides one-stop comprehensive energy solutions with environmental protection, high efficiency and cost reduction for industrial parks, logistics parks, commercial complexes, highway service areas and urban stations, opening a new stage for the integration of power and energy transportation.
With the continuous growth in the number of new energy commercial vehicles, online car-hailing, heavy trucks and passenger cars, traditional energy supplement models expose prominent shortcomings. Centralized fast charging easily causes distribution network overload and high grid expansion costs. Excess photovoltaic power generated during the day cannot be consumed locally, resulting in serious light abandonment losses. Separately operated charging and battery swapping stations fail to realize interconnected energy scheduling, leading to high comprehensive operation costs. Targeting industry pain points such as load imbalance, low green power utilization, insufficient energy supplement efficiency and scattered operation and maintenance, Xinrui Energy breaks the barriers of single equipment and single energy supplement business. Centering on system integration and digital intelligence, the company launches the integrated PV-storage-charging-swapping service platform to realize full-link independent control and optimal configuration of energy production, storage, consumption and supplement.
Xinrui Energy’s PV-storage-charging and battery swapping comprehensive service platform is not a simple superposition of hardware, but realizes bottom-level interconnection, homologous data and collaborative linkage of five core units:
Photovoltaic Power Generation System: Efficient photovoltaic modules are laid on factory roofs, parking sheds and idle open spaces to produce clean green power on-site. The generated power is preferentially supplied to internal charging, battery swapping equipment and on-site loads, realizing energy self-sufficiency from the source, reducing reliance on municipal power and cutting carbon emissions.
Energy Storage Regulation System: Equipped with standardized liquid-cooled energy storage units to store excess photovoltaic power and implement peak shaving and valley filling strategies based on peak-valley electricity price differences. During peak charging and battery swapping periods, the stored energy is released to relieve transformer load pressure, eliminate high grid capacity expansion investment, smooth photovoltaic output fluctuations, and ensure stable and uninterrupted power supply for energy supplement.
Intelligent Fast Charging System: Equipped with high-power DC supercharging equipment, compatible with private cars, online car-hailing, sanitation vehicles and other multiple models. It meets short-term extreme fast energy supplement demands with flexible matching of fast and slow charging, adapting to fragmented charging scenarios.
Automatic Battery Swapping System: Adopts automated battery swapping equipment to complete full-power battery replacement in several minutes. It adapts to the high-frequency turnover demands of logistics heavy trucks, taxi fleets and operational vehicles, solving the industry problem that long-time charging restricts transportation capacity.
EMS Intelligent Energy Management System (Core Brain): As the digital core of the overall solution, it connects full data of photovoltaic inverters, energy storage PCS, charging piles and battery swapping station battery management systems. Adopting edge computing and cloud collaborative algorithms, it dynamically dispatches energy flow at the millisecond level. Photovoltaic power generated during the day is prioritized for charging and swapping loads, with surplus power stored in energy storage. Energy storage discharges to guarantee power supply during peak electricity consumption, and charges at night during low-price valley periods to create arbitrage benefits. It synchronously links the backup battery pool of swapping stations to realize mutual reuse of vehicle and stored energy, achieving visualized, automated and intelligent management of station-wide energy and completely eliminating equipment data silos.
The collaborative operation of the five modules forms a complete closed loop of "self-production - storage - fast charging - fast swapping - intelligent scheduling", enabling stations to realize self-sufficient green power, multi-mode efficient energy supplement, intelligent load stabilization and continuous optimization of comprehensive costs.
Green and Low-Carbon with High Local Green Power Consumption: On-site consumption of photovoltaic power and absorption of excess daytime light energy by energy storage systems greatly improve the self-use rate of green power, reduce municipal power purchase and fossil energy consumption, help enterprises obtain carbon neutrality and green park certifications, and support the construction and application of various low-carbon and zero-carbon demonstration projects.
Dual-mode Energy Supplement Balancing Efficiency and Transportation Capacity: The integrated layout of fast charging and battery swapping meets both scattered charging demands of private cars and high-frequency turnover needs of operational vehicles. A single station can serve multiple new energy vehicle models, improving site efficiency and passenger flow, and solving the problems of single revenue and resource idle in single-business models.
Peak Shaving and Valley Filling to Reduce Comprehensive Energy Costs Significantly: Relying on energy storage and EMS intelligent scheduling, it avoids high electricity prices during grid peak hours and creates arbitrage profits through peak-valley price differences. It stabilizes the instantaneous high-power load of charging and swapping, eliminates the need for additional power distribution capacity upgrading, greatly reduces one-time grid transformation investment and shortens the project investment recovery cycle.
Intelligent Unified Operation and Maintenance Simplifying Station Management: The integrated cloud platform uniformly monitors operating data of photovoltaic power generation, energy storage status, charging piles and battery swapping stations. It automatically generates reports on power consumption benefits, carbon emissions and equipment operation and maintenance, with real-time fault alarms and remote control functions, greatly reducing manual operation and maintenance difficulty and management costs.
Modular Design for Replicable and Standardized Implementation: The modular solution can adjust photovoltaic installed capacity, energy storage capacity and charging/swapping equipment ratio on demand. It is applicable to logistics parks, freight hubs, industrial parks, commercial parking lots, highway service areas, urban bus stations and other scenarios, providing full-set delivery services including standardized complete equipment and digital operation platforms.
The in-depth integration of the new power system and new energy transportation has become an inevitable industry trend. The independent construction mode of single photovoltaic, energy storage, charging or swapping equipment can no longer meet customers’ comprehensive demands for carbon reduction, cost reduction and efficiency improvement. Breaking the positioning of a single equipment supplier, Xinrui Energy, as a comprehensive energy service provider, builds a full-link connection covering the power generation side, energy storage side and transportation load side. It integrates distributed green power production, flexible energy storage regulation, multi-vehicle energy supplement and digital intelligent operation, creating a replicable, high-benefit and zero-carbon friendly new generation of intelligent energy supplement station model.
In the future, Xinrui Energy will continuously iterate EMS intelligent scheduling algorithms, expand value-added functions such as vehicle-to-grid (V2G) interaction and battery echelon utilization, and improve the integrated PV-storage-charging-swapping product matrix. The company will provide customized comprehensive energy solutions for industrial and commercial customers and various parks nationwide, empower the green transformation of transportation energy through technological innovation, and continuously inject industrial momentum into the implementation of dual-carbon goals.
