What is Charging Pile?

Charging piles, whose function is similar to that of gas pumps inside gas stations, can be fixed on the ground or wall, installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential community parking lots or charging stations, and can charge various models of electric vehicles according to different voltage levels. Charging piles can be classified in different ways as follows.


1 According to the installation method

It can be divided into floor-mounted charging piles and wall-mounted charging piles. The floor-mounted charging post is suitable for installation in the parking space not close to the wall; the wall-mounted charging post is suitable for installation in the parking space close to the wall.

2 According to the installation location

It can be divided into public charging piles and special charging piles. The public charging pile is built in the public parking lot (library) combined with parking spaces to provide public charging service for social vehicles; the special charging pile is built in the unit (enterprise) own parking lot (library) for the internal personnel of the unit (enterprise), and the charging pile built in the individual own parking space (library) to provide charging for private users. Charging piles are usually built in combination with parking spaces in parking lots (warehouses).

3 According to the number of charging interfaces

It can be divided into one pile and one pile with multiple charges.

4 According to the charging mode

Charging piles can be divided into DC charging piles, AC charging piles and AC/DC integrated charging piles.

5 According to charging speed

There are two charging methods: regular charging (slow charging) and fast charging (fast charging). Charging time varies according to different vehicle batteries, ambient temperature, etc. Slow charging is usually full in 5-10 hours, fast charging can be full in 20-30 minutes 80%, 1 hour completely full.

Equipment manufacturers and charging operators.

1 The charging pile equipment itself does not have too high technical content, unified standards,good compatibility,stable quality and proper construction will do. Competitive differences are mainly reflected in the stability of the equipment produced, cost control, brand reputation and bidding ability.

2 Charging operation is related to many aspects.

The basic profit model of charging operation are: service fee, power price difference, value-added services, and the upcoming national subsidies. As an emerging industry, and is involved in the state control of the power industry, service charges and electricity prices are subject to national guidance, can not be freely priced, the geometry of subsidies have not seen a specific number, the space for value-added services and a variety of commercial expansion is still in the process of exploration, so although a large number of charging piles are under rapid construction, but the charging operation of the industry itself is full of uncertainty.

3 At present, there are four kinds of construction and operation modes: government-led, business-led, mixed mode, and crowdfunding mode.

1) Government-led is invested and operated by the government. The advantage is the strong promotion, the disadvantage is the financial pressure, operational inefficiency, not necessarily adapt to the market.

2)Enterprise-led is invested and operated by enterprises, with electric vehicle sales and charging pile production. The advantage is the high efficiency of operation and management, the disadvantage is the lack of unified management, may produce disorderly competition.

3) Hybrid model is supported by government participation and enterprises are responsible for construction. The advantage is that it can make the government and enterprises complement each other and promote industrial development faster, but the disadvantage is that it is influenced by policies.

4) Crowdfunding model is to integrate the government, enterprises, society and other parties to participate. The advantage is that it can improve the utilization of social resources, adapt to the market, and focus on user needs. The disadvantage is that it is difficult to integrate the interests of all parties, and it ultimately depends on the guidance of policies.
