The difference between DC charging station and AC charging station
Source:
1. Charging speed
DC charging station: Due to its high charging power, usually above 60kW, there are other specifications such as 30kW, 120kW, 160kW, 360kW, 380kW, etc. Supercharging stations can even reach 800kW, so the charging speed is faster. In an ideal situation, the battery can be fully charged within 20-150 minutes;
AC charging station: The charging power of AC charging stations is generally low, usually around 7kW, and there are other specifications such as 3.5kW and 11KW, so the charging time is longer, usually taking 8-15 hours to fully charge the battery;
2. Charging pile cost
DC charging station: The manufacturing and installation costs of DC charging stations are relatively high, requiring large volume transformers and AC-DC conversion modules, which are much more expensive than AC charging stations;
Communication charging station: The manufacturing and installation cost of communication charging stations is relatively low, the structure is simple, the volume is small, and it is easy to install and popularize;
3. Volume of charging station
Due to the large number of internal components, the volume of the DC pile is relatively large, and its charging gun head has nine holes;
The modules of the communication station are relatively few and the volume is small, with a 7-hole charging gun head;
4. Impact on batteries
DC charging station: DC charging stations may cause certain damage to the battery during the charging process, as their output current is high and they release more heat during charging. High temperatures may lead to a sudden decrease in battery capacity and damage to the battery cells;
AC charging station: Due to its low charging power and long charging time, AC charging stations do not cause excessive impact on the battery, which is beneficial for extending battery life;
5. Protection level
DC charging station: Generally, DC charging stations are more commonly used in complex outdoor scenarios, facing more complex weather such as rain and snow, with higher protection levels, generally above IP54 protection level.
AC charging station: Generally, DC charging stations are more commonly used in indoor garage scenarios, facing relatively simple environments and requiring lower levels of protection.
6. Adapt to the scene
DC charging station: Due to its fast charging speed, DC charging stations are suitable for installation in charging stations next to highways, taxi and bus stops, and other scenarios that require high charging time.
Communication charging station: Communication charging stations are suitable for installation in residential areas, parking lots, and other places to meet daily charging needs, especially suitable for night charging because users can charge at night and the battery will be fully charged the next day when using the vehicle.
