Problems solved by technology

However, due to the limited load capacity of the grid, the large amount of power required by the charging pile will bring huge pressure to the grid
For example, when a large number of electric vehicles are charged in one time period, a large amount of electric energy will be output from the grid, resulting in a short-term capacity shortage of the grid
Excessive stress on the grid reduces the quality of charge for charging consumers

Abstract

The invention, which relates to the field of electrical power, provides a charging and energy storage integrated system comprising a voltage and current conversion system, an energy storage system, acharging system, and a data monitoring system. The voltage and current conversion system is configured to carry out current conversion or voltage conversion among a power grid, an energy storage system, and a charging system. The energy storage system is configured to store the electrical energy transmitted by the power grid and provide the electric energy for the charging system and / or the powergrid; the charging system is configured to charge an external electrical device by using the electric energy provided by the power grid and / or the energy storage system; and the data monitoring systemis configured to acquire electrical energy regulation parameters and regulate electric energy transmission among the power grid, the voltage and current conversion system, the energy storage system,and the charging system based on the electrical energy regulation parameters. Therefore, the charging quality for charging an external electrical device is enhanced.

Description

technical field [0001] The invention relates to the field of electric power, in particular to an integrated system for charging and storing energy. Background technique [0002] With the widespread use of new energy in various fields, more and more electric vehicles and charging piles have been put into use. Charging piles can be incorporated into the charging network system. In order to meet the charging needs of users, it is necessary to plan the charging network system according to factors such as urban overall planning, power grid planning, user distribution, and user needs. [0003] At present, electrical equipment such as electric vehicles can directly obtain power from the grid in the charging network system through charging piles. However, due to the limited load capacity of the grid, the large amount of electric energy required by the charging pile will bring huge pressure to the grid. For example, when a large number of electric vehicles are charged in a certain...
