The development history of energy storage technology dates back to quite early times. However, in recent years, due to various factors such as environmental protection, energy security, technological advancements, and policy support, the energy storage sector has received greater attention and seen more development—particularly with the emergence of energy storage vehicles. The advent of energy storage vehicles helps meet the needs of today’s societal development and facilitates the achievement of energy transition and emission reduction goals in the transportation sector. Meanwhile, continuous innovation and application of energy storage technologies in the automotive sector have also laid a firmer foundation for their future prospects. I. Advantages of using static transfer switches in energy storage vehicles The GSS three-phase static transfer switch (STS) holds significant value in energy storage systems. A static transfer switch is an electronic-based switching device that enables power transfer through the on/off operation of electronic components. Compared to traditional mechanical transfer switches, high-speed contactless static transfer switches and rapid power-failure detection enable swift, safe, and efficient switching between dual power sources. They offer greater reliability and stability. In the application of energy storage vehicles, GSS static transfer switches are primarily used to facilitate rapid switching between different power sources while ensuring a stable power output during the switching process. They play the following important roles: 1. Energy conversion: Energy storage systems typically involve charging and discharging processes; during these processes, STSs enable quick switching between various power sources, thereby ensuring efficient conversion and transmission of energy. 2. Fault protection: STS is capable of detecting faults in the power grid or energy storage system, and it can quickly switch to a backup power source in the event of a fault, thereby ensuring the safe and stable operation of the energy storage system. 3. Load management: The STS can achieve intelligent switching between different power sources based on load requirements, enabling the energy storage system to respond more flexibly to varying load demands and thereby improving energy utilization efficiency. 4. Emergency backup power supply: In energy storage vehicles, the STS static switch can be used to connect to an emergency backup power supply, such as a backup battery pack or other alternative power generation devices, to provide continuous power support in the event that the main power source fails.
