Jun 21, 2023
From the adoption demand, the overall cost of DC electric vehicle charging stations is high, and the cost of AC electric vehicle charging stations is low. If you install your own electric vehicle charging station, it is recommended to use AC electric vehicle charging station, AC electric vehicle charging station charging power can reach 7KW, the average full charge takes 6-10 hours, when you get home from work, you can park the electric car directly, and the next day after charging it does not affect the use. At the same time, the demand for power distribution is not very large, and the general 220V power supply can be accessed. Individuals do not have too high standards for full time, DC electric vehicle charging stations are suitable for new residential areas, parking lots, and places with relatively large charging mobility.
From the perspective of installation, the installation cost of DC electric vehicle charging stations is relatively high, and the line laying is even higher than the equipment cost. AC electric vehicle charging stations can be used when connected to a 220V power supply. AC electric vehicle charging station larger charging power is 7KW, DC electric vehicle charging station charging power is usually 60KW to 80KW, single gun input current can reach 150A--200A, which is a huge test for power supply lines, most of the usual community transformers can not bring several such electric vehicle charging stations, residential communities almost can not be installed. Some large vehicle DC electric vehicle charging stations can reach 120KW to 160KW, charging current can reach 250A, the construction line standards are very strict, the distribution cabinet load standards are very high.
From the user's point of view, it is definitely the faster the charging efficiency, the better. Fuel vehicle refueling is a matter of a few minutes, electric vehicle charging if the time is too long, will definitely affect the customer experience, if the use of DC electric vehicle charging station, charging Z more than 1 hour to achieve, if the use of AC electric vehicle charging station, may take 6--10 hours to complete the charge, if you encounter the need to use a car or run a long distance, this kind of charging method is extremely inconvenient, obviously there will be no fuel vehicle refueling convenience to come quickly.
