The differences between AC charging piles and DC charging piles are: charging time, car charger, price, technology, society, and application.
1. In terms of charging time, it takes about 1.5 to 3 hours to fully charge the power battery at a DC charging station, and 8 to 10 hours to fully charge at an AC charging station.
2. In terms of car chargers, the AC charging station charges the power battery and needs to be charged with the car charger on the car. The direct charging of the DC charging station is also the biggest difference from DC charging.
3. In terms of price, AC charging piles are cheaper than DC charging piles.
4. In terms of technology, DC piles can more effectively realize group management and group control, flexible charging, and optimize investment and yield through technical means such as charging piles. In many cases, AC piles are tricky in these aspects, and the heart is powerless of.
5. In terms of society, since DC piles have greater technical requirements for capacitors, when investing in the construction of charging stations with DC piles as the main body, it is necessary to increase the power capacity, and there are more safety issues. In terms of safety management, DC pile groups are often more complicated and strict, while AC piles are more flexible. Many cities and real estates allow AC piles to be installed in underground garages, but very few are willing to build DC pile groups in underground parking lots, mainly because of Security considerations.
6. In terms of application, DC piles are suitable for operational charging services such as electric buses, electric leasing, electric logistics, electric private cars, and electric network reserved cars. However, due to the high charging rate, it is easier for operating companies to estimate investment costs. In the long run, private electric vehicle users will be the main force, and private communication piles will have more room for growth.
