Application of dry-type transformers in electric vehicle charging stations

As environmental protection and energy-saving concepts are becoming more and more popular, electric vehicles are gradually becoming the core development direction of the future transportation field with their green and efficient characteristics. The widespread popularity of electric vehicles is highly dependent on a sound charging infrastructure. As a key node for electric vehicle energy replenishment, the performance and reliability of electrical equipment in charging stations are undoubtedly the top priority to ensure their efficient operation. Among many key equipment, dry-type transformers play an indispensable role in the stable operation and efficient charging of charging stations due to their unique advantages.

Application scenarios of dry-type transformers in electric vehicle charging stations

1.Regular charging stations

Regular charging stations mainly focus on meeting the daily charging needs of electric vehicles. Compared with fast charging stations, their charging power is relatively small, but the charging time is longer. Even so, dry-type transformers still play an important role in regular charging stations. The stable voltage and current it outputs are a solid guarantee for the normal operation of charging equipment and can significantly improve charging efficiency. Not only that, the low loss characteristics of dry-type transformers can also effectively reduce the operating costs of charging stations, achieving a win-win situation of economic benefits and functional services.

2. Fast charging station

Fast charging stations are responsible for replenishing a large amount of electric energy for electric vehicles in a short period of time. It can meet the urgent needs of users for emergency charging. During fast charging operations, the charging power is strong, which places strict requirements on the load capacity and stability of the transformer. With its excellent overload capacity and good heat dissipation performance, dry-type transformers can easily cope with the high current impact during fast charging, effectively ensuring that the charging process is smooth and smooth. For example, in many fast charging stations in highway service areas, dry-type transformers continuously provide stable power support for multiple charging piles, effectively ensuring the rapid energy replenishment of electric vehicles.

3. Charging facilities in residential areas

As electric vehicles gradually enter thousands of households, the construction of charging facilities in residential areas is also accelerating. With its advantages of small size, extremely low noise, and flexible installation, dry-type transformers are particularly suitable for installation in the distribution room or near charging piles in residential areas. It can provide a reliable power supply for the electric vehicle charging piles in the community, fully meeting the daily charging needs of residents. At the same time, due to its low noise during operation, it will not cause any interference to the daily life of residents.

Advantages of dry-type transformers in electric vehicle charging stations

1. Easy maintenance

The dry-type transformer has a simple structural design, which makes its maintenance workload relatively small. At the same time, its good sealing can effectively block the intrusion of dust and moisture, greatly reducing the incidence of equipment failure. In addition, the dry-type transformer has a long maintenance cycle, which not only reduces maintenance costs, but also reduces power outage time, effectively improving the operating efficiency of the charging station.

2. High safety

There is no oil inside the dry-type transformer, which eliminates the safety hazards such as oil leakage and fire caused by oil filling equipment from the root. In electric vehicle charging stations with frequent personnel exchanges, high safety is undoubtedly crucial. The insulation material used has excellent heat resistance and insulation properties, which can effectively prevent the occurrence of electrical failures.

3. Significant energy-saving effect

Dry-type transformers use advanced core materials and winding designs, which can significantly reduce no-load losses and load losses. During the long-term uninterrupted operation of electric vehicle charging stations, a large amount of electricity can be saved, significantly reducing operating costs.

4. Good environmental performance

Dry-type transformers do not produce oil pollution and harmful gases during operation, which is highly consistent with the green and environmentally friendly development concept upheld by electric vehicles. This helps to significantly reduce the pollution of the surrounding environment by charging stations and create a cleaner and healthier charging environment.
