Analyze the advantages and disadvantages of the four configurations of electric vehicle charging stations
Electric vehicles are a trend in the current automotive industry. Future electric cars and hybrid cars will become the mainstream of the automotive industry. At present, some big automakers in Germany have shifted their focus to the manufacture of electric vehicles, and China, as a populous country, is accelerating the development of electric vehicles. With the electric vehicle supporting facilities also improved, electric charging piles and electric vehicle charging stations were included in key construction projects. Maybe someone would ask if electric car charging poles and electric car charging stations aren't the same thing? Although they are all used to charge cars, they are essentially different. The electric vehicle charging station and the electric charging car charging pile are two completely different concepts. The charging pile is fixed on the ground and utilizes a special charging interface to provide AC power to the electric vehicle with the on-board charger and has corresponding communication and metering. Fees and security features. The electric vehicle charging station refers to a charging station, which is the same size as the current gas station. The charging station contains a total of four modules: power distribution system, charging system, battery scheduling system, and charging station monitoring system. After understanding the difference between them, the focus is to introduce the configuration of the electric vehicle charging station: The configuration of the electric vehicle charging station is divided into four types: conventional charging, mechanical charging, portable charging, and rapid charging. Each configuration has its advantages and its disadvantages. What are the advantages and disadvantages of these four charging station configurations? A conventional charging mode: A charging station is configured with 20 to 40 electric cars. This charging mode takes into consideration that it is fully charged with evening valley power. Although the cost is reduced, the charging equipment is not fully utilized. Another model is to configure a charging station with 60-80 electric cars. The charging equipment is fully utilized but increases configuration costs and peak power load. Second, mechanical charging mode: Electric car users can rent a fully charged battery at any time and replace the exhausted battery. This mode improves vehicle usage and saves the user time. The mechanical charging mode is very suitable for taxis and running business vehicles, but it requires the standardization of batteries and electric vehicles. This method still needs to invest in various aspects of management and improved design of electric vehicles and batteries. Third, portable charging mode: The external power source of the portable charging mode can be directly connected to the villa or general residential area. There must be a centralized underground parking garage in the general residential area, which will be more secure. The portable charging mode can be used to improve the charging of electric vehicles on the basis of existing resources, but the design of specific schemes is more complicated, and it is necessary to organize supporting schemes according to the power supply facilities of the community or villas. It will take a long time to popularize the portable charging mode. After all, this is the construction of private houses in residential buildings. Fourth, fast charging mode: The quick charging station can generally charge 8 electric vehicles at the same time. The charging speed is fast, the waiting time is short, the battery life is long, and there is no need to build a matching parking lot. The use of fast charging chargers is inefficient, installation costs are high, and billing is complicated. The new energy vehicle charging station is currently in the domestic implementation stage. With the increasing number of electric vehicles, corresponding supporting facilities such as charging stations will be further improved.
