As the global green energy transition accelerates, islands far from the mainland are also actively embracing the concept of sustainable development and gradually building a green transportation system. A British island is vigorously promoting the popularization of electric vehicles while planning and laying out charging infrastructure to support the travel needs of residents and tourists on the island. However, the island’s special geographical location and power grid conditions have brought considerable challenges to the deployment of EV chargers.
Challenge
Grid frequency fluctuations
The power supply of the island relies on a small independent power grid, and the grid frequency often fluctuates, which poses a challenge to the compatibility and stability of electric vehicle supply equipment (EVSE). The customer deployed an energy management system (EMS) to monitor and adjust frequency changes in real-time to ensure the balance of energy supply and demand. This special environment requires the EV charger to have high compatibility and rapid response capabilities, be able to adapt to frequency fluctuations and adjust charging power, and ensure a stable and efficient charging process.
Special environment of the island
The high humidity and salt spray environment in the island area poses a severe challenge to the durability of the EV charger. Salt and water vapor in the air can easily corrode the metal parts, electrical contacts, and casing of the EV charger. Long-term exposure may cause equipment performance degradation or even failure. In addition, extreme weather conditions such as strong winds, heavy rains and typhoons common on islands pose a threat to the structural strength, waterproof performance and stability of internal components of EV chargers, increasing the difficulty of equipment design and maintenance.
SCU EV charging solution:
30kW wall-mounted EV charger: Compact design, suitable for sites with limited space, providing efficient and stable charging services.
60kW CCS2 EV charger: With fast charging capabilities, it can meet electric vehicles’ efficient charging needs and provide users with a convenient experience.
SCU EV chargers are specially designed to adapt to the island environment. Its protection level reaches IP54, with dustproof, waterproof, and salt spray corrosion resistance, and can operate stably for a long time in high humidity and high salt spray environments. In addition, SCU EV chargers can seamlessly connect to the customer’s EMS system, realize dynamic adjustment by real-time response to grid frequency fluctuations, and ensure the safety and stability of the charging process.
Technical highlights: The core advantages of SCU EV chargers
- Reliability: The EV chargers have undergone rigorous environmental adaptability tests and can operate stably, safely and efficiently for a long time in various special environments: high humidity, high salt fog, dust pollution, high temperature and cold, including hardware durability, electrical safety, compatibility and anti-environmental interference capabilities, ensuring continuous reliable charging services for electric vehicles.
- Intelligent frequency modulation capability: By linking with the EMS system, the equipment can automatically adjust the charging power according to the grid frequency, reduce the impact of grid fluctuations on charging efficiency, and avoid charging interruptions or equipment damage caused by grid instability.
- Efficient and fast charging: DC fast EV chargers can significantly shorten the charging time, improve the efficiency of electric vehicles, and meet the high-frequency charging needs of limited charging facilities in island areas. Its fast charging capability can help electric vehicle users complete charging in a short time and reduce waiting time.
Assisting the green transformation of islands
The successful implementation of this project not only provides convenient electric vehicle charging services for local residents but also lays the foundation for the construction of green transportation networks on islands. The reliability and intelligent characteristics of SCU EV chargers make it a reliable choice for building green infrastructure in complex environments.
In the future, SCU will continue to use innovative charging solutions to support new energy transformations in more special scenarios and contribute to global sustainable development.
