1, Save space.

When designing DC charging modules or combined charging stations, it is crucial to consider heat dissipation issues. Consequently, these charging stations often require a large size and occupy significant space. However, a 20KW fast charger can be much smaller and more easily installed on a pedestal or a wall.


2, Lower power supply requirements.

Compared to high-power DC chargers, 20KW DC fast chargers have lower power requirements, which makes them suitable for places with insufficient power capacity. Additionally, the 20KW DC charger is a good fit for parking lots, convenience stores, schools, hospitals, and other locations where cars are parked for extended periods. Typically, a 20KW DC charger can provide a 20KWh charge in 1 hour, which is equivalent to 30-50% of an electric car’s power capacity.


Compared to the 3-phase 22KW charger, the 20KW DC fast charger has wider compatibility since not all electric vehicles support AC 22KW charging. Most only support a maximum of 7KW AC charging.
