Types of car charging piles
Leave a message
Car charging piles can be mainly divided into the following categories:
Classification by charging method:
AC charging pile (slow charging): The AC power of the power grid is transmitted to the vehicle, and the vehicle charger is used to convert it into DC power to charge the battery. Suitable for scenes such as homes and company parking lots, with low installation costs, low charging power, and long charging time.
DC charging pile (fast charging): Directly convert the electric energy in the power grid into DC power and input it into the battery of new energy vehicles. The charging speed is fast and suitable for scenes such as high-speed service areas and public charging stations. The equipment cost is high and the grid load requirements are strict.
Portable charging pile: Lightweight and easy to carry, it charges new energy vehicles through ordinary household power supply and is suitable for temporary or emergency use.
Classification by installation scenario:
Public charging pile: Set up in public areas such as urban streets, shopping malls, and parking lots, including AC and DC types, to meet the needs of most users.
Dedicated charging pile: set up for specific units or individuals, such as company fleets, taxi-dedicated stations, etc., and the right of use is limited to specific user groups.
Home charging pile: installed in private parking spaces or garages, usually AC charging piles, suitable for users with high daily frequency.
Classification by interface type:
National standard interface charging pile: adopts national standard interface (GB/T), unifies market charging standards, and facilitates users to use public charging facilities.
International standard interface charging pile: such as CHAdeMO, CCS, etc., mainly used for charging facilities for imported vehicles and international markets.
Dedicated interface charging pile: some brands develop dedicated interfaces for their new energy vehicles to improve charging efficiency and compatibility, but the scope of application is limited.
