Outdoors fixed installation fast-charging system with small shock load for parking space

Abstract

The invention provides an outdoors fixed installation fast-charging system with a small shock load for a parking space. The outdoors fixed installation fast-charging system with the small shock load for the parking space aims to ensure the power supply stability and the power grid safety of an installation and application site, and realize the management requirement of the quality of power grid supply on the premise of rated load control of a user side under an original low-voltage electric supply power grid circuit. The outdoors fixed installation fast-charging system with the small shock load for the parking space is characterized by comprising a control / inversion component, an intelligent control component I, an AC / DC conversion component, an intelligent control component II, a storage battery pack, a direct-current busbar and a charging part, wherein the intelligent control component I is provided with a power input end connected with an external electric supply grid and a power output end connected with the AC / DC conversion component; the AC / DC conversion component is connected to the direct-current busbar; the storage battery pack is connected onto the direct-current busbar in a hanging way, is controlled by the intelligent control component II, and comprises a storage battery management component and a plurality of capacitor storage battery packs; the charging part is powered from the direct-current busbar and is controlled by the intelligent control component II.

Description

Technical field [0001] The invention relates to an outdoor parking space fixed installation small impact load fast charging station system, which is used for power distribution load and power quality management for end users of a low-voltage power distribution system. Background technique [0002] At present, various electric vehicle charging piles and mobile and fixed fast charging stations have many related control and management technologies. The fast charging stations under the known technical system structure must use 10kV grid dedicated distribution load The power distribution network and lines can only be constructed in China, and some off-grid energy storage charging stations are designed and manufactured using solar power generation systems. There are still some objective problems in the implementation of the above two methods, such as: 1. The connection between dedicated line charging stations and the municipal power grid involves the distribution of power supply loads ...

AI Technical Summary

Problems solved by technology

There are still some objective problems in the implementation of the above two methods, such as: 1. The connection between the dedicated line charging station and the city grid involves the distribution of power supply load and the management of power quality under the conditions of local users. From the perspective of power supply technology, it is often subject to some Irresistible constraints (apply for a patent 10KV high-voltage load line or independent high-power low-voltage power end users to increase and upgrade the capacity of power transformers, etc.) make it impossible to implement installation and construction

2. The fully off-grid charging station is completely isolated from the mains grid. Although it does not involve a dedicated line for the grid, the applicability and flexibility of the distribution layout are reduced due to the relevant environment and system structure, thereby reducing the effectiveness of the system. Utilization rate, market acceptance is very low
