Description

Technical Field

[0001] The present invention relates to the technical field of energy storage charging and discharging, and in particular to a mobile integrated storage and charging device. Background Art

[0002] The volatility and randomness of the distribution network load are becoming increasingly significant, making the planning and operation management of the distribution network more difficult. After a large number of distributed resources are connected, how to ensure the safety and high-quality power supply of the distribution network is a core issue. Secondly, since the construction of the distribution network lags behind the growth of electricity demand, the distribution capacity in some areas is insufficient, and the problems of short-term heavy overload and low voltage for users are prominent. If only the structural upgrade and transformation of the distribution network is implemented to solve the problem, the economic cost is large, and the contradiction between the rapid growth of user load and the realization of efficient and accurate investment is becoming increasingly prominent. While distributed photovoltaics enters a stage of prosperous development, the power grid's absorption capacity is facing increasing pressure. Due to the rapid development of new energy such as photovoltaics, the transformation of the power grid has not kept up with its pace, resulting in a huge increase in both transformer capacity and power grid absorption pressure. In some areas, problems such as insufficient transmission and transformation capacity and difficulties in peak load absorption during holidays have emerged, which have affected the stable operation of the power system. Therefore, for power grid companies, how to solve this challenge and promote the absorption of new energy is an important task currently faced, and it is urgent to take multiple measures to resolve the problem of new energy absorption. At the same time, the level of electric vehicle infrastructure construction is difficult to keep up with the rapid development of electric vehicles, resulting in many problems such as difficulty in finding charging piles, long queues, and long time consumption. The satisfaction of electric vehicle users has declined, which has restricted the development of electric vehicles to a certain extent.

[0003] In this context, energy storage technology and equipment are developing rapidly. It can realize the efficient and friendly use of green energy, improve the randomness and volatility of distributed new energy, and reduce energy costs through energy storage, such as peak shaving and valley filling, demand response, and grid peak and frequency regulation. However, in terms of the participation of distributed energy storage in the operation and management of distribution networks, most of the energy storage devices are still fixed energy storage, which is not movable, has low energy storage utilization, and does not integrate multiple module functions such as charging piles, trailers, and 220V sockets. There is still a lack of a mobile storage and charging integrated device for distribution network management, user charging, and disaster relief and power supply. While meeting the needs of distribution network management, it can alleviate the charging needs of electric vehicle users and serve as a temporary power source to ensure power supply in disasters. Summary of the invention

[0004] In view of this, the main purpose of the present invention is to provide a mobile integrated storage and charging device. Aiming at the short-term heavy overload, high / low voltage of users, photovoltaic power reverse transmission and other types of operation scenarios in the operation of the distribution network, as well as the problem of difficulty in charging for electric vehicle users, the device integrates energy storage batteries, DC charging piles, trailers, 220 / 380V AC low-voltage sockets and other modules.
