Layout considerations and manufacturing difficulties of bicycle charging pile PCB

  • With the popularization of green travel concepts and the rapid development of the electric bicycle market, the demand for bicycle charging piles is growing. As the core component of bicycle charging piles, the design and manufacturing quality of PCB (printed circuit board) is directly related to the performance, safety and reliability of the entire charging equipment. This article will discuss the layout considerations and manufacturing difficulties of bicycle charging pile PCB.
  • What is a bicycle charging station: A bicycle charging station is a device that provides charging services for electric bicycles. It is usually installed in public places such as residential areas and shopping malls, and supports charging multiple electric bicycles at the same time. It has a self-stop function when fully charged to ensure charging safety, and through intelligent management, it is convenient for users to view charging status and consumption details.
  • Let us take a look at the upstream and downstream industries of the bicycle charging pile industry and the related industry overview.

  • It can be clearly observed that the upstream industry mainly focuses on the production of materials themselves and related products and equipment, while the midstream industry mainly focuses on the production and installation of bicycle charging piles, and its technical details and process requirements are more critical. Entering the more detailed mid- and downstream fields, we can find its close connection with the PCB industry (printed circuit board industry). Finally, the downstream industry covers a variety of applications and services to meet the diverse needs of the market.

  • Take the lithium battery we are familiar with as an example, because various control systems, such as lithium battery and other charging pile products, require PCB to implement.
  • So what are the PCB products in the bicycle charging pile industry like? The editor specially found several charging pile boards of our JSY-MK-1092 for everyone to see, which are as follows.

From the above picture, what are the characteristics of the bicycle charging pile PCB board?

  • 1. Detailed circuit patterns are printed on the PCB board, including the layout of various electronic components such as resistors, capacitors, integrated circuits and other connectors.
  • 2. There is a clear area division, such as "card swiping area", indicating that the charging pile supports card payment or identity authentication function.
  • 3. The PCB version information is clearly marked, such as " USY1092M(V1.1) " " JSY1092M(V1.1) " , etc. This helps to track and manage different versions of circuit boards.
  • 4. The PCB board integrates multiple protection devices, such as overvoltage protection, overcurrent protection, short circuit protection and overheating protection, to ensure the safe and reliable operation of the charging pile under various environmental conditions.

What should we pay attention to in the design and manufacturing of bicycle charging pile PCB ?

  • First, since the bicycle charging pile equipment itself is small in size and belongs to high-power charging pile equipment, the charging pile contains a large number of electronic components and electronic circuits. The most worrying problem is the adhesion of the charging pile relay contacts . When the contacts are adhered, the charging current may become unstable, increasing the risk of burning and explosion of the charging pile. The most serious consequence is a safety accident.

Therefore, when designing and manufacturing bicycle charging pile PCB boards, we should pay attention to the following points:

  • 1. Follow the signal integrity principle as much as possible, isolate high-frequency, low-frequency, analog and digital signals, and reduce signal interference. Rationally wire and set up appropriate hierarchical structures to achieve circuit stability and reliability.
  • 2. Considering the high-power characteristics of the 2-way charging pile, good heat dissipation performance should be designed.
  • 3. When PCB wiring is directed and laid out, the wiring should avoid being too dense and crossed to reduce electromagnetic interference and crosstalk.
  • 4. The manufacturing process of PCB boards complies with relevant standards and specifications, such as IPC-A-600H and IPC-J-STD-001E, to ensure quality and consistency.
  • 5. Prevention of relay contact adhesion: Choose reliable quality relays and ensure that the contact materials are resistant to high temperatures and wear. Design a reasonable heat dissipation structure around the relay to reduce the contact temperature. Use auxiliary circuits or monitoring mechanisms to detect and handle relay contact adhesion.
  • 6. Since the charging pile contains a large number of electronic components, attention should be paid to electrostatic protection during the manufacturing and assembly process to avoid damage to the components caused by static electricity.

What are the difficulties in manufacturing bicycle charging pile PCB?

  • 1. Heat dissipation problem: High-power charging piles require good heat dissipation design to avoid high temperature causing component failure, especially relay contacts.
  • 2. Welding accuracy: Temperature, time and pressure must be strictly controlled during the welding process to ensure the quality of the solder joints and prevent welding defects.
  • 3. Relay contact adhesion: This is a key difficulty in manufacturing. The contact material should be high temperature resistant and wear resistant, and a reasonable heat dissipation structure should be designed to reduce the contact temperature. At the same time, it is necessary to ensure that the contacts are opened or closed synchronously to avoid adhesion and circuit failure.

Why choose JSY-MK?

  • Shenzhen Jiansiyan Technologies Co., Ltd.'s patented "control method, storage medium, control device and relay for preventing contact adhesion" provides an effective solution. The technology tests the closing or opening action time of the electric control device and accurately controls it according to the occurrence time of the AC zero crossing to ensure that the opening or closing operation is performed at the right time, thereby avoiding the problem of contact adhesion.
