What is the power output of fast charging stations?

Public charging stations are mostly 7KW slow chargers and 30KW fast chargers. Below are specific details about charging stations: 1. Introduction: Charging stations function similarly to fuel dispensers at gas stations. They can be fixed on the ground or walls, installed in public buildings (such as office buildings, shopping malls, public parking lots) and residential community parking lots or charging stations. They can charge various types of electric vehicles according to different voltage levels. 2. Functionality: Charging stations (piles) can provide timed charging, measure electricity consumption, and calculate charging costs, serving as terminals for citizens to purchase electricity. Meanwhile, to improve the efficiency and practicality of public charging stations (piles), functions such as multi-vehicle charging per station and charging for electric bicycles will be gradually added in the future.
While researching electric vehicles, I noticed significant variations in fast charger power outputs. Most public chargers range from 60kW to 120kW, with upgraded 150kW units becoming increasingly common at highway service areas. Tesla's V3 Superchargers can reach 250kW, while Porsche's dedicated chargers even exceed 350kW. However, actual charging speeds are constrained by vehicle limitations - my car's battery management system, for instance, caps at 150kW. Grid support is another factor, as older urban transformers may struggle with chargers exceeding 120kW. Thermal management of charging connectors also plays a crucial role, with overheating triggering automatic power reduction. When selecting chargers, I recommend checking real-time power via apps rather than relying on nominal ratings for more accurate expectations.
When I first switched to an electric car, I was also curious about this. Currently, mainstream fast charging stations are around 120kW, providing enough charge for 200 kilometers in half an hour. There's a significant difference in power among different brands: State Grid commonly offers 60kW, XPeng has 180kW, and NIO's battery swap stations support up to 500kW, though such high power isn't usually needed in practice. Weather has a big impact; in winter, cold batteries can halve the charging power. Choosing a charger depends on your car's charging port specifications—my car, with a 400V system, works best with a 150kW charger. Recently, I've found that charging at night is more time-efficient, as the voltage is stable and power fluctuations are minimal.
