Monitoring system for electric automobile battery charging and replacing station

Abstract

The invention relates to a monitoring system for an electric automobile battery charging and replacing station. The system comprises a superior system, an electricity distribution monitoring system, a charging monitoring system, a battery replacement monitoring system and a video monitoring system; a monitoring work station, a server, a printer, an electricity distribution system communication management machine and an electricity utilization information collecting terminal are connected with a network exchanger of the charging monitoring system through a local industrial Ethernet; a network exchanger of the electricity distribution monitoring system is connected with a communication gateway of the superior system through the local industrial Ethernet; an intelligent communication terminal of the battery replacement monitoring system is connected with the network exchanger of the charging monitoring system through the local industrial Ethernet; and a video server of the video monitoring system is connected with the communication gateway of the superior system through the local industrial Ethernet. The system can meet the requirement of electric energy complement of large commercial vehicles and small passenger vehicles and can realize omnibearing, effective and real-time monitoring on the battery charging and replacing of electric automobiles.

Description

technical field [0001] The invention belongs to the field of low-voltage power distribution technology and power electronics technology, and specifically relates to a monitoring system for an electric vehicle charging and swapping station. Background technique [0002] At present, there are usually two types of charging and swapping stations for electric vehicles: [0003] 1. The electric vehicle charging station, park the electric vehicle at the vehicle charging position, use a high-power DC charger to charge the vehicle, the charging time is longer, the charging station occupies a larger area, and the effective use area is smaller; [0004] 2. Electric vehicle battery replacement station, park the electric vehicle at the exchange potential, remove the battery, replace it with a fully charged battery, and use the sub-box charging system to charge the rechargeable battery in sub-boxes. The battery replacement time is short, but a special battery replacement workshop is requi...

AI Technical Summary

Problems solved by technology

[0003] 1. The electric vehicle charging station, park the electric vehicle at the vehicle charging position, use a high-power DC charger to charge the vehicle, the charging time is longer, the charging station occupies a larger area, and the effective use area is smaller;

[0004] 2. Electric vehicle battery replacement station, park the electric vehicle at the exchange potential, remove the battery, replace it with a fully charged battery, and use the sub-box charging system to charge the rechargeable battery in sub-boxes. The battery replacement time is short, but a special battery replacement workshop is required. At present, large-scale bus battery replacement stations occupy a very large area, and the battery replacement workshop needs about 400 square meters;

[0007] The electric vehicle charging stations that have been built at present cannot fully meet the functions of charging and replacing large and small vehicles, and occupy a large area, have very low efficiency, and the construction and operation costs are very high. We can only redesign the electric vehicle charging and replacing stations to meet the current construction. need

In addition, most of the existing electric vehicle charging and swapping facilities in my country serve specific objects, and their independent operation and service methods are difficult to meet the requirements of the majority of electric vehicle users for convenient, fast and free power services

In addition, as a part of the power grid, the operation and use of electric vehicle charging and swapping facilities are closely related to the safe operation of the power grid. However, the independent operation and service of each charging and swapping station prevents the management system of the power grid from effectively monitoring and managing them.
