La XY-EVDDY400-520kW is a high-power DC charging system developed for applications that require fast energy delivery, flexible power configuration, and high system availability.
Unlike conventional AC-coupled charging architectures, the system uses a high-performance DC-DC charging architecture to reduce unnecessary AC-to-DC conversion losses. This helps improve energy efficiency while simplifying system integration in applications where DC power is already available from photovoltaic generation or energy storage systems.
The wide 300V–1000V constant-current output range allows the charger to flexibly accommodate different passenger and commercial EV platforms, including high-voltage EV architectures.
For charging operators, fleet managers, energy developers, and infrastructure investors, the system provides a scalable platform for high-power charging stations, commercial fleets, heavy-duty vehicles, and renewable-energy-integrated charging projects.
The XY-EVDDY400-520kW features a wide-voltage DC charging architecture capable of delivering constant-current output across the 300V–1000V range.
Its high-performance modular DC-DC charging design allows the number of charging modules to be configured according to actual power requirements, with a maximum system output of 520kW.
The XY-EVDDY400-520kW is designed to work alongside renewable energy and energy storage systems, making it suitable for integrated PV + Storage + EV Charging applications.
By connecting the charger with photovoltaic generation and battery energy storage, operators can optimize the use of locally generated electricity and reduce dependence on grid power during periods of high charging demand.
The system can also support off-grid charging operation when integrated with a suitably configured energy storage and power management system.
The XY-EVDDY400-520kW can be seamlessly integrated into an advanced medium- and high-voltage architecture combining SST solid-state transformers, energy storage, and high-rate Virtual Power Plant (VPP) systems.
This architecture enables coordinated energy management between the grid, renewable energy sources, energy storage, and EV charging loads, helping charging infrastructure adapt to the increasing power requirements of next-generation high-voltage EV platforms.
Such an architecture provides a scalable foundation for future high-power charging networks and renewable-energy-integrated charging infrastructure.
The optimized system architecture helps reduce cooling requirements compared with high-power systems that rely heavily on complex thermal management solutions. This creates greater flexibility for enclosure and protection design in demanding operating environments.
The XY-EVDDY400-520kW is therefore suitable for applications where equipment may be exposed to dust, humidity, temperature variations, or other challenging environmental conditions.
Potential applications include:
For specific projects, the protection rating and environmental configuration can be customized according to installation conditions and application requirements.
The DC-oriented architecture of the XY-EVDDY400-520kW can help simplify system design in photovoltaic-powered charging projects.
When PV generation, energy storage, and EV charging are integrated through an optimized DC architecture, certain additional power-conversion equipment, such as standalone inverters, may be reduced depending on the overall system configuration.
This can help lower hardware procurement requirements and potentially reduce overall system costs.
Potential benefits include:
The actual equipment configuration and cost savings depend on the project architecture, grid connection requirements, PV capacity, and energy storage configuration.
High-power charging does not have to mean excessive operating noise. The XY-EVDDY400-520kW incorporates optimized thermal management and system control strategies to support efficient heat management and low-noise operation.
Reduced cooling requirements also provide greater flexibility for equipment enclosure and protection design.
The system is engineered for reliable operation in commercial and industrial charging environments where equipment availability and operating stability are critical.
The XY-EVDDY400-520kW is designed with N+1 redundancy to improve system availability and operational reliability.
Key charging modules can be serviced through hot-swappable maintenance, reducing downtime during maintenance and allowing operators to restore system capacity more efficiently.
If a single module fails, the remaining modules can continue supporting system operation, helping maintain continuous charging service.
The high-power output and wide voltage range make the XY-EVDDY400-520kW suitable for electric heavy-duty trucks that require high-power charging and short turnaround times.
The system can support electrification projects in mining environments where high-power charging, robust protection, and flexible energy integration are important.
For electric port equipment, logistics vehicles, and commercial fleets, the system can provide high-power charging while working alongside renewable energy and energy storage systems.
Fleet operators can deploy high-power charging infrastructure to reduce vehicle downtime and coordinate charging loads with on-site energy storage.
The system can be integrated with photovoltaic generation and battery energy storage to create renewable-energy-powered charging infrastructure and optimize energy utilization.
The modular 400kW–520kW architecture provides a scalable foundation for high-throughput charging stations serving passenger EVs, commercial vehicles, and heavy-duty fleets.
