Classification by charging method
DC charging pile (fast charging)
DC charging pile, commonly known as "fast charging", directly converts 380V industrial electricity into DC power to charge the car battery. Since DC power can directly charge the power battery, the charging speed is relatively fast, and it can generally be charged to 80% of the power in half an hour. However, the cost of DC charging piles is relatively high, and it has a certain impact on the battery life, so it is usually used for emergency charging or fast charging during long-distance travel.
2. AC charging pile (slow charging)
AC charging pile, commonly known as "slow charging", converts 220V AC power into DC power through an on-board charger to charge the car battery. Although the charging speed is slow, it generally takes 6-8 hours to fully charge, but the cost of AC charging piles is low, and the damage to the battery is less, which is suitable for daily family use or long-term charging at night.
Classification by installation location
1. Public charging piles
Public charging piles are mainly installed in public places such as shopping malls, hotels, scenic spots, and highway service areas for social vehicles to charge. Public charging piles have the characteristics of high charging power, fast charging speed, and large number, which can meet the charging needs of new energy vehicles of different brands and models.
2. Special charging piles
Special charging piles are mainly installed in fixed parking spaces such as residential areas and office places of new energy vehicle owners for charging specific vehicles. Special charging piles have the characteristics of moderate charging power and low charging cost, which makes it convenient for car owners to charge anytime and anywhere.
3. Classification by power size
1. Low-power charging pile
The charging power of a low-power charging pile is generally below 3.3kW, which is suitable for home use or small parking lots. Although the charging speed is slow, the price is relatively low, which is suitable as a home backup or temporary charging device.
2. Medium-power charging pile
The charging power of a medium-power charging pile is generally between 7kW-20kW, which is suitable for public places such as shopping malls, hotels, and scenic spots. The charging speed of medium-power charging is moderate and the price is moderate, which can meet the charging needs of most new energy vehicles.
3. High-power charging pile
The charging power of a high-power charging pile is generally above 50kW, which is suitable for places such as highway service areas and large parking lots. The charging speed of a high-power charging pile is very fast, and it can fully charge an electric vehicle in a short time, but the price is relatively high, which is suitable for long-distance travel or emergency charging.
4. Classification by communication method
1. Wired charging pile
The wired charging pile communicates and transmits data with the electric vehicle through a wired method. This type of charging has a faster charging speed, but requires the use of a dedicated charging cable and interface, which is not easy to carry and move.
2. Wireless charging piles
Wireless charging piles communicate and transmit data with electric vehicles wirelessly. This type of charging does not require the use of charging cables and interfaces. You only need to park the electric vehicle in a designated location to charge. Although the charging speed of wireless charging is relatively slow, it has the advantages of convenience and beauty, and is one of the important directions for the development of charging piles in the future.
Summary
As an important supporting facility for new energy vehicles, charging piles are of various types and have different functions. As a buyer, you need to make comprehensive considerations based on your actual needs and scenarios when choosing charging. I hope this article can provide you with some useful references and suggestions to help you better choose and use charging piles.
