What is the wattage of new energy vehicle charging piles?

Charging piles are divided into two main categories: AC piles and DC piles. Generally, AC piles have a power of 7KW and use 220V single-phase power supply. Below is relevant information about electric vehicles: 1. Two types of charging piles: Charging piles are divided into AC piles and DC piles. Generally, AC piles have a power of 7KW and use 220V single-phase power supply; DC piles come in various power levels such as 30KW, 60KW, 100KW, 150KW, and 200KW. The actual charging power is determined by the matching result between the electric vehicle's battery parameters and the charging pile, and it varies with the charging state. 2. Depending on the vehicle's battery capacity: The exact wattage depends on the vehicle's battery capacity. Generally, small and medium-sized electric vehicles have a capacity of 18 kWh when fully charged. If it takes 6 hours to fully charge, then 18/6 = 3 kW. To calculate, you need to know the input voltage and current of the charger. Moreover, during charging, the current consumed by the charger continuously changes and does not stay at a fixed value. The calculated result is only a reference value.
As a long-term electric vehicle user, I find the topic of charging station power quite important. I personally use a home charging station with a power output of around 7 kilowatts, which is pretty much the standard level. A full charge usually takes about 8 hours—for example, when I plug it in after getting home in the evening, it's fully charged by the next morning, which is super convenient. As for public charging stations, the power varies widely: common fast chargers range from 50 kilowatts to 150 kilowatts. Like the last time I used a 120-kilowatt station at a highway service area, it added over 200 kilometers of range in just half an hour, saving both time and hassle. However, it's important to note that very high power may not be suitable for all households, as the home electrical grid might not support it. It's best to have a professional check the voltage and safety measures before installation. Overall, choose the power based on your lifestyle—7 kilowatts is sufficient for urban commuters, while frequent long-distance drivers should prioritize high-power public stations.
