What is the difference between DC charging pile and AC charging pile? Which is better?
Jul 27, 2023
Difference 1: DC pile power is large, AC pile power is small
The charging power of DC charging pile is large, the power varies from 30kw ~ 480kw, 20/30/40kw small DC charging pile is suitable for household + commercial, and the DC pile with higher power is only suitable for commercial use.
The power of AC charging piles is relatively small, common 3.5kw, 7kw; A small number of charging piles have a power of 11kw and 21kw.
Difference 2: DC pile charging is fast, AC pile charging is slow
DC charging pile adopts direct current, and the charging speed is fast; The AC charging pile adopts alternating current, and the charging speed is slow. A 55kw car battery pack, it only takes 1-3 hours for the DC pile to be fully charged, while the AC pile takes about 8 hours.
The difference between AC charging pile and DC charging pile mainly has these aspects: different charging time, different charging methods, different electricity consumption, different appearance, different charging power, and different installation locations.
Difference 3: DC pile volume is large, AC pile volume is small
Due to the large number of internal components, the volume of the DC pile is relatively large, and its charging gun head is nine-hole. The modules of the AC pile are relatively few, the volume is relatively small, and its charging tip is 7 holes.
Difference 4: DC piles are more suitable for commercial use, and AC piles are more suitable for household use
Due to the large power and the rated voltage exceeding the household electricity voltage, the DC pile is more suitable for commercial use. Only 20/30/40kw small DC piles, can be used for domestic use. The AC pile has small power, and household electricity meets its rated voltage, which is more suitable for household use.
The above is the general difference between DC charging piles and AC charging piles. Who are these two types of piles suitable for?
For private car owners, installing a 7kw AC pile can meet daily needs. For taxi/ride-hailing/truck drivers, the daily charging demand is high, and it is more suitable to install a small DC charging pile of 20/30/40kw. As for the DC pile with greater power, it is more suitable for the construction of charging stations.
