In today’s rapidly developing new energy vehicle market, Sinopoly, FAW and State Grid have reached a strategic cooperation to jointly explore the innovative application of energy storage technology in the field of EV power swap stations. One of the highlights of this cooperation is the 4 sets of energy storage cabinets provided by Sinopoly, with a total energy storage capacity of 1MWh. Each energy storage cabinet is equipped with an advanced PCS (Power Conversion System), providing strong support for the efficient operation of EV power swap stations.
As an efficient energy storage device, the energy storage cabinet has many significant advantages. It can store electrical energy when the power supply is sufficient, and then release this energy during peak power demand or when there is a shortage of power, achieving peak shaving and valley filling of the power grid. In addition, the energy storage cabinet also has the characteristics of high energy density, fast response time and long service life, making it a key part of the modern energy system. Its flexible storage and release functions effectively solve the problem of unbalanced power supply and demand between day and night, help to achieve peak load regulation of the power grid, and can also effectively deal with the time and instability problems of wind and solar power generation, providing strong support for the large-scale grid connection and consumption of renewable energy.
The energy storage cabinets provided by Sinopoly this time will be mainly used in EV power swap stations to provide stable energy support for the battery swap mode. The addition of energy storage cabinets not only improves the energy supply capacity and stability of the swap station, but also reduces the impact on the power grid by charging the battery during the low-power period at night. At the same time, through V2G technology, excess energy is released to the power grid during the peak power consumption period in the daytime, acting as a virtual power plant to assist the power grid in meeting the peak load demand, achieving efficient use and optimal allocation of energy.
Compared with the traditional charging mode, the EV power swap mode has many unique advantages. The swap speed is fast, and it only takes a few minutes to complete the battery replacement, which greatly shortens the vehicle’s energy replenishment time and improves the vehicle’s operation efficiency, especially suitable for high-frequency operation vehicles such as taxis and online ride-hailing vehicles. At the same time, the battery swap mode is conducive to the centralized management and maintenance of batteries. Professional personnel can carry out unified detection, maintenance and charging of batteries in the swap station, extend the service life of batteries, reduce the battery failure rate, and ensure the safe driving of vehicles. In addition, the swap station can flexibly allocate batteries according to the operation demand of vehicles, realize the optimal allocation of battery resources, improve the utilization rate of batteries, and reduce the operation cost.
At present, the project is still in the initial pilot stage, but it has shown great application potential and development prospects. Sinopoly, FAW and State Grid are all full of confidence in this cooperation and plan to gradually promote the energy storage cabinets and EV power swap mode to the whole province on the basis of successful pilot. With the promotion process, it is expected to promote the coordinated development of energy storage and transportation fields in the whole province, and contribute to the efficient use of energy, the promotion of the electrification process of transportation, and the sustainable development of local economy.
