Reliable, High-Power EV Charging Solution
Split-type DC charging piles are one of the mainstream equipment types in the public charging field. They feature a separate power cabinet and charging terminal design, connected remotely via cables. Compared to integrated DC charging piles, this structure excels in reliability and power allocation flexibility, providing electric vehicle users with efficient and convenient charging services.
It also adapts to high-demand charging scenarios such as urban areas and highways, contributing to improved charging convenience and energy efficiency, aligning with the current development trend of upgrading charging infrastructure.
Reliability Design Ensures Continuous Operation
Split-type DC charging piles enhance operational stability and reduce downtime through multiple design improvements, ensuring service continuity. The equipment uses modular power units, supporting multi-unit grid connection and hot-swapping.
When a single module fails, the system automatically calls upon redundant modules to take over, eliminating the need for system shutdown. Maintenance personnel only need to replace the faulty module, significantly reducing repair time.
Furthermore, the equipment generally boasts an IP54 or higher protection rating, capable of withstanding harsh outdoor environments such as heavy rain, sandstorms, and high temperatures, adapting to complex application scenarios such as urban public spaces and highway service areas, extending the equipment's service life.
The safety protection and real-time monitoring system is equally comprehensive, continuously monitoring key parameters such as charging voltage, current, and temperature. It provides multiple protections including AC over/under voltage, DC overcurrent, and insulation fault protection, with accurate fault identification. This ensures the safety of equipment and vehicles while further reducing the possibility of unexpected downtime.
High Power Output Meets Rapid Recharge Needs
High power output is a significant advantage of split-type DC charging piles and is key to enabling users to charge quickly and reduce parking time. With the promotion of high-power charging facilities, the power range of this type of equipment now covers 180kW to 600kW.
Some megawatt-level systems can achieve even higher power through parallel connection of multiple cabinets, adapting to the needs of different vehicle types such as private cars, electric buses, and light trucks. Industry data shows that in 2025, the average power of a single charging gun in public charging stations nationwide reached 46.5 kW, with charging efficiency increasing by 33% year-on-year.
Split-type DC charging piles generally boast energy conversion efficiencies exceeding 95%, with some products meeting the new national standard's Level 1 energy efficiency requirements (efficiency ≥ 96.5%), achieving high power output while minimizing energy loss.
For example, using a 240kW-level split-type DC charging pile, a typical electric vehicle can be charged from 20% to 80% in 15–25 minutes, significantly reducing user waiting time and alleviating charging anxiety during long-distance travel.
Flexible Structure Adaptable to Multiple Charging Scenarios
The split-type design offers greater flexibility in space utilization and layout adjustments, making it a suitable solution for charging network construction in urban and highway areas. In urban scenarios, such as commercial districts, transportation hubs, and community parking lots, this design can save approximately 70% of terminal space.
A single power cabinet can connect to multiple charging terminals, adapting to different parking space layouts and supporting dynamic power allocation to meet the needs of simultaneous charging of multiple vehicle models, improving the utilization efficiency of public charging resources.
By the end of 2025, the number of public charging facilities nationwide had reached 4.717 million, with the proportion of split-type DC charging piles in urban charging stations continuing to increase.
Regarding highways, as of the same period, a total of 71,500 charging piles had been built in highway service areas nationwide, covering more than 98% of service areas. Split-type DC charging piles, with their high power and high reliability, have become an important component of highway charging stations, contributing to the construction of an intercity fast-charging network and aligning with the requirements of the "Three-Year Action Plan for Doubling the Service Capacity of Electric Vehicle Charging Facilities (2025-2027)" to strengthen the layout of high-speed charging facilities.
Energy-Saving Technologies Improve Energy Efficiency
In terms of energy utilization, split-type DC charging piles further respond to the industry trend of energy conservation and emission reduction through technological optimization. The equipment adopts advanced power conversion technology, with some products using LLC resonant topology and SiC MOSFET devices, which helps reduce conversion losses, achieving a power factor of up to 0.98, meeting the State Grid's Class A equipment standards.
Meanwhile, some systems can be seamlessly integrated with battery energy storage devices, combining photovoltaic (PV) systems to form a photovoltaic-storage-charging microgrid. This allows for power supply during peak hours and energy storage during off-peak hours, thereby optimizing the power structure and alleviating grid pressure.
Furthermore, the equipment supports intelligent power allocation based on vehicle battery status, preventing idle power resources and increasing power utilization by over 40%. This achieves the dual goals of efficient charging and energy-saving operation, providing support for the sustainable development of the new energy vehicle industry.
