Frequently Asked Questions About the FusionCharge Liquid-Cooled Charging Dispenser DT500L1-EUA2
What is the DS720-720LEUA5, and what is its role in the charging system?
What is the DS720-720LEUA5, and what is its role in the charging system?
The DS720-720LEUA5 is the liquid-cooled power unit of the Huawei FusionCharge system. It handles the central power conversion from the three-phase AC grid to DC and supplies up to 12 charging points simultaneously via connected dispensers. As such, it forms the heart of every FusionCharge-based fast-charging station.
What is the maximum charging power of the DS720-720LEUA5?
What is the maximum charging power of the DS720-720LEUA5?
The usable charging power at the vehicle is limited by the connected dispenser, which provides a maximum output of 480 kW.
Why does the DS720-720LEUA5 use hybrid cooling?
Why does the DS720-720LEUA5 use hybrid cooling?
The AC and DC modules are uniformly supplied with liquid cooling via a water pump, which enables a significantly higher power density than in air-cooled systems. Two fans reliably remove the resulting waste heat from the system. This results in stable operating temperatures, an extended service life for the power modules, and reduced noise emissions of ≤ 55 dB(A) in Silent Mode. This is a decisive advantage for continuous operation in high-traffic locations.
For which locations is the DS720-720LEUA5 suitable?
For which locations is the DS720-720LEUA5 suitable?
The Power Unit is designed for public fast-charging infrastructure, such as highway rest stops, shopping centers, airports, fleet locations, and urban charging parks. Thanks to its IP55 protection rating, an operating temperature range of -35 °C to +50 °C, and a permissible installation altitude of up to 4,000 m, it is suitable for virtually all site conditions in Europe and beyond.
How can the DS720-720LEUA5 be integrated into existing backend systems?
How can the DS720-720LEUA5 be integrated into existing backend systems?
The Power Unit supports 4G and Ethernet communication, as well as the OCPP protocol, which is supported by most common charging platforms and operator backends. In addition, an integrated web UI is available for local monitoring and remote maintenance.
Can the system be combined with a solar power system or a battery storage system?
Can the system be combined with a solar power system or a battery storage system?
Yes. The FusionCharge system is designed to integrate with photovoltaic systems and energy storage systems. This integration makes it possible to increase the self-consumption of solar power, reduce grid peaks, and operate the charging station in a way that benefits the grid.
