With the continuous upgrading of various technologies of new energy vehicles, the new energy vehicle industry has ushered in rapid development, followed by the increasing demand for charging by users.
Charging pile is an indispensable infrastructure for new energy vehicles. It provides power supply services for electric vehicles, enabling them to drive conveniently.
That's about New energy vehicle charging pile How much do you know? Everything you want to know is here. Let's have a look!

Type of Charge Point
01
According to different installation methods
It is mainly divided into floor mounted charging piles and wall mounted charging piles.
Floor type charging pile: the floor type charging pile is suitable for installation in the parking space not close to the wall.
Wall mounted charging piles: wall mounted charging piles are suitable for installation in parking spaces near walls.
02
Depending on the installation location
It is mainly divided into public charging piles, special charging piles and self use charging piles.
Public charging pile: The public charging pile is a charging pile built in the public parking lot (garage) combined with parking spaces to provide public charging services for social vehicles.
Special charging pile: the special charging pile is the self owned parking lot (garage) of the construction unit (enterprise), and the new energy vehicle charging pile is the charging pile used by the internal personnel of the unit (enterprise).
Self use charging pile: The self use charging pile is a charging pile built in an individual's own parking space (garage) to provide charging for individuals.
03
Depending on the charging interface
It is mainly divided into one pile with one filling and one pile with multiple filling.
One charging pile: one charging pile only charges one electric vehicle.
Multiple charging in one pile: one charging pile has multiple interfaces, which can charge more than one electric vehicle at the same time.
04
According to different power supply modes
It is mainly divided into AC charging pile and DC charging pile.
DC charging pile: the DC charging pile is directly connected to the power grid, which can directly charge the battery of electric vehicles. Generally, three-phase four wire system or three-phase three wire system is used for power supply. The output voltage and current can be adjusted in a wide range, which can realize rapid charging of electric vehicles.
AC charging pile: The AC charging pile does not have charging function, but only provides power output. To charge the electric vehicle, it needs to connect the on-board charger. Electric vehicle charging pile As the power of the electric vehicle on-board charger is generally small, the AC charging pile cannot realize fast charging.
AC/DC integrated charging pile: AC/DC charging pile can realize both DC charging and AC charging. If there is a large demand for charging in the daytime, DC mode can be used for fast charging, and AC charging can be used for slow charging when there are few charging users at night.

Composition and structure of charging post
01
Power Supply
The charging pile needs to be connected to the power supply to provide power.
The power supply can be from the grid, or green energy equipment such as solar panels.
02
Control panel
The control board is the core part of the charging pile, which can control and monitor the charging pile.
Including power calculation, automatic stop function, charging speed control, etc.
03
Charging interface
The charging interface refers to the connection between the charging pile and the electric vehicle, which can exchange information and transmit power.
The charging interface includes DC fast charging and AC slow charging.
04
Protective barrier
The protective barrier is a physical safety device that can protect the charging pile and charging equipment from the impact of external environment, such as bad weather and humidity.
05
Housing
The shell is the external package of the charging pile, which can protect the equipment inside the charging pile from the damage of the external environment, and also play a role in beautification and decoration.
06
Support frame
The support frame is a device used to support the charging interface, which is usually fixed on the charging pile. The support frame can adjust the height and angle of the charging interface to adapt to different models of cars.

Charging mode of charging post
01
DC fast charging
DC fast charging pile can provide higher charging power, usually from 30kW to 120kW or higher.
DC charging pile can greatly shorten the charging time of new energy vehicles and realize fast charging.
Such charging piles are mainly distributed in expressway service areas, large parking lots and other places to provide convenient charging services for long-distance vehicles.
However, the construction cost of DC charging piles is relatively high, and the requirements for the power grid are relatively strict.
02
AC slow charging
AC slow charging charging post uses single-phase or three-phase AC power to charge new energy vehicles. The charging power is relatively low, generally between 7kW and 22kW.
The installation of AC charging pile is relatively simple and the cost is relatively low. It is suitable for slow charging scenarios such as home, community and office.
It can charge the vehicle at night or in idle time to meet daily use needs.
03
Wireless charging
Wireless charging technology mainly includes electromagnetic induction type, radio wave type and magnetic resonance type.
According to the charging state, it can be divided into static and dynamic states. The basic principle is to use two mutual inductance coils to install on the ground and the chassis of the car body, generate excitation current through the input coil, and complete wireless charging through induction of the output coil.
The current wireless charging technology requires that the distance between the vehicle and the ground equipment is close, the coil must be aligned to complete the charging, and it can only be one-to-one.
At present, wireless charging is still in the experimental stage, and it will take some time for it to be widely put into the market.

What factors to consider when charging
01
Self charging demand
First, you need to be clear about your charging needs.
If charging is mainly at home or at work, and there is no rush to replenish energy, then slow charging is enough.
If frequent charging or long-distance travel plans are needed, consider fast charging.
02
Battery performance and connector compatibility
Secondly, pay attention to the specific characteristics of the vehicle battery.
First, electric vehicles of different brands and models may use different types of charging connectors. It is necessary to ensure that the selected charging pile is compatible with the electric vehicle and can provide the correct charging connector.
Second, some batteries may be more suitable for slow charging. In general, slow charging is more conducive to extending the service life of batteries.
03
Charging cost
Thirdly, the charging cost needs to be comprehensively considered.
Charging costs vary with different charging periods. In general, the charging cost of slow charging is relatively low, while that of fast charging is relatively high. New energy vehicle maintenance Therefore, if you are not in a hurry and want to be economical, you can consider using slow charging mode.
