What is the charging power of electric vehicles?

Electric vehicle charging power is 7KW/14kW. New energy charging piles are divided into two types: AC charging piles and DC charging piles. AC charging piles are for slow charging, while DC charging piles are for fast charging. New energy DC charging piles convert the 380V power supply into high-current DC charging voltage through a transformer, with a charging current that can reach 32A and a charging power of up to 45KW. New energy fast charging pile equipment adopts an integrated AC/DC structure. It can achieve both DC charging and AC charging. During the day when there is a high volume of charging business, DC charging is used for fast charging. At night when there are fewer users at the charging station, AC charging can be used for slow charging operations. According to the installation location, charging piles can be divided into public charging piles and dedicated charging piles: Public charging piles are built in public parking lots combined with parking spaces to provide public charging services for social vehicles. Dedicated charging piles are built in parking lots owned by construction units for use by internal personnel. Private charging piles are built in personal parking spaces to provide charging for private users. Charging piles are generally constructed in conjunction with parking spaces in parking lots. The protection level of charging piles installed outdoors should not be lower than IP54. The protection level of charging piles installed indoors should not be lower than IP32.
I've been driving an electric car for almost two years now, and the changes in charging power have been quite significant. A regular household socket only delivers 1 to 3 kilowatts, which barely gets you anywhere after an overnight charge, making it suitable for unhurried daily commutes. After installing a dedicated charging station, the power can be boosted to 7 to 11 kilowatts, allowing a medium-sized battery to be fully charged in just a few hours. Public fast-charging stations are even more exciting, with DC charging power ranging from 50 kilowatts to 350 kilowatts. For example, Tesla's Supercharger supports 250 kilowatts, enabling a majority of the range to be replenished in under half an hour—ideal for long-distance trips. However, the higher the power, the faster the charging, but it may also impact battery health. Using slow charging over the long term is generally safer. The vehicle's battery and supporting systems are also crucial; always check the manual to avoid overloading. I always remind everyone to choose a charging method based on their actual needs rather than blindly chasing high speeds.
As an average car owner, my experience is that charging power varies greatly. Home slow charging typically ranges from 3 to 7 kW—it's cost-effective and quiet, charging overnight to full by morning, which is quite convenient. When traveling, I look for public fast chargers starting at 50 kW, with the highest reaching 350 kW. It's like a charging feast—super fast, adding dozens of kilometers of range in just ten minutes. However, in rural areas, charging stations are scarce, often forcing reliance on low-power equipment and long waits. Charging speed also depends on the car model; newer Max versions support faster charging, while older models are slower. Overall, shorter charging times save time, but high-power stations cost more. I recommend frequently checking map apps to find suitable charging points that balance efficiency and cost.
