Automobile charging pile manufacturing

Construction of global charging facilities is expected to accelerate. New global energy vehicles are developing at a high speed. Charging and power exchange are two important ways to make up energy. At present, charging is a plan for many car companies to choose. With the development of the new energy vehicle industry, charging facilities have also developed rapidly as its supporting service industry. The construction of electric vehicle charging stations, as necessary supporting facilities for the promotion of new energy vehicles, has become an important industry that supports the development of the new energy vehicle industry, stimulates investment demand, and promotes economic growth. Next, we will discuss the development of electric vehicle charging piles together.

Electric vehicle charging piles are divided into two modes: DC and communication.

1、New energy vehicle power batteries are mainly replenished by charging and power replacement.

2、According to different charging technology, charging piles can be divided into DC piles and AC piles. DC charging piles, commonly known as “fast charging,” can provide enough power to meet fast charging requirements. AC charging piles, commonly known as “slow charging”, just play the role of controlling the power supply, and the charging speed is slow.

DC charging
Charging method: Provide DC power supply directly for power batteries.
Power level: Charging pile power generally exceeds 60kW.
Charging speed: charging speed faster.
Cost: The equipment is more complex and the cost is higher.
Volume size: larger volume, larger area.
Application scenarios: centralized locations for operating vehicles such as buses, taxis, logistics vehicles, heavy trucks, as well as public service locations such as charging stations, highway service areas.

AC charging
Charging method: Provide AC power for the vehicle charger.
Power level: Charging pile power is generally 7kW.
Charging speed: Slow charging speed.
Cost: The technology is less mature.
Volume size: Small size and easy to install.
Application scenario: residential community, public parking lot, shopping center, etc.

DC fast enough class: according to the number and structural form of the charging gun

DC charging piles are mainly divided into: 30kW, 60kW, 120kW, 150kW, 180kW, 240kW, etc. and a larger power charging pile according to the power size. In addition, DC charging piles can also be divided into single guns and double guns according to the number of charging guns: divided into integrated and multi-body types according to the structure form.

Types of DC charging piles

Single gun: The separate charging interface charges new energy vehicles, and the charging power is the maximum output power of the equipment.

Multi-gun: Two charging interfaces can be one new energy vehicle or charging two new energy vehicles at the same time. Charging power is accumulated for the output power of the two charging interfaces. When only one car is charged, the power is the maximum power of the charging pile; when both cars are charged, the receiving power of the bicycle is half power.

One-on-one: All components of the charging pile are integrated.

Separation: separate control units, billing units, charging interfaces, human-computer interaction interfaces and other parts.

High-voltage fast charging is the future development trend of electric vehicle charging piles.

Fast charging can be divided into high voltage fast charging and high current fast charging. High-current fast filling requires high heat dissipation, while high-voltage fast charging can improve safety and energy conversion efficiency. Therefore, high-voltage fast charging has been favored by most pile companies and car companies.

At present, the charging pile industry is in the process of development from low voltage/low to high voltage/high power.

The charging module is the main technical barrier of the fast charging pile.

The charging module is the “heart” of fast charging piles. Key technologies focus on the topology of power electronic power conversion circuits. With the increase of the voltage and power level of the charging module, the difficulty in all aspects has also increased. At the same time, it must ensure its safety. And reliability and progress have improved the technical threshold of the charging module.

Production steps of electric charging piles

The production process of charging piles can be divided into five steps: design, procurement, processing, assembly, and testing.

Step 1: Design. During the design phase, a specific charging pile solution needs to be formulated according to the needs of customers. The designer needs to consider the height of the charging gun, the location of the charging port, and the charging speed. At the same time, in the design process, the appearance and stability of the appearance must be considered to ensure the appearance and stability of the charging pile.

Step 2: Procurement. After formulating a specific loading pile plan, the necessary materials and accessories must be purchased. These materials and accessories include charging controllers, charging plugs, cables, aluminum alloy cases, control chips, etc. The materials and accessories purchased must have stability, reliability and quality assurance.

Step 3: Processing. After purchasing the required materials and accessories, a series of processing processes are required, such as sheet metal processing, casting, injection molding, precision processing, etc. to make the final loading pile product. In the processing process, we must pay attention to the processing accuracy and processing quality to ensure the stability and reliability of the loading pile.

Step 4: Equipment. After the processing is completed, it is necessary to assemble the processed components, including installing charging controllers, charging plugs, cables, etc. During the assembly process, you must pay attention to the installation location and connection method of each component to ensure that the structure of the charging pile is stable, safe and reliable.

Step 5: Test. After completion of the assembly, strict testing and testing are required to ensure that the loading piles meet the relevant standards and regulations of the country and regions. The test process includes electrical characteristics testing, charging speed testing, safety performance testing, etc. Only by passing various tests and inspections can the charging pile enter the market.

This electric AC charging pile is an intelligent, easy to install charging pile that allows you to add intelligent services and remotely manage charging piles. Combined with mobile applications, it provides a series of functions to control your charger status, user, charging schedule, energy consumption, etc. Intelligent features make it an ideal choice for home or commercial charging.
