The Art of Producing the Main Control Panel of a Charging Pile

Precision design lays the foundation

Everything starts with design. Engineers carefully draw up a design blueprint for the PCB (printed circuit board) based on the functional requirements of the charging pile. This blueprint not only carries the logic and layout of the circuit, but also serves as the cornerstone of the subsequent production process. Every detail needs to be repeatedly scrutinized to ensure the rationality and efficiency of the design.

Brush solder paste

Fine welding and frame building

On the production line, the PCB board undergoes a precise printing process to apply solder paste accurately to the contacts that need to be soldered. Subsequently, the high-speed placement machine accurately pastes components such as capacitors, resistors, and IC integrated circuits on the solder paste at an astonishing speed. Next, through the reflow soldering technology, the solder paste melts and re-solidifies at high temperature, firmly fixing the components on the PCB board, building a solid frame for the main control board of the charging pile.

AOI Inspection

Strict quality inspection to ensure quality

Quality is the lifeline of the product. After welding, the PCB board needs to be strictly inspected by the AOI optical inspection machine to ensure that every welding point meets the standards. Unqualified products will be reworked immediately, while qualified ones will become semi-finished motherboards and enter the next stage of the assembly process.

Plug-in welding

Manual assembly, excellence

For non-standard components, such as transformers, inductors, and wiring terminals, experienced workers are required to manually insert them. With their superb skills, they install these special-shaped parts one by one on the semi-finished motherboard and fix them with a wave soldering machine. Although this step is time-consuming and laborious, it is another improvement in product quality.

Test packaging

Comprehensive testing to protect safety

After assembly, the motherboard needs to go through a series of rigorous tests: power-on test, operation test, and three-proof (waterproof, dustproof, and anti-corrosion) treatment. Failure in any test will result in the product being returned for rework. Only motherboards that have passed multiple levels of screening and are foolproof can be officially put on the market.

Installation journey of the charging pile main control panel

Accurate positioning, safety first

During the installation process, the motherboard must first be accurately placed in the reserved position of the charging pile housing. At the same time, in order to ensure the safe operation of the charging pile, two thermistors must be installed in the center of the motherboard to monitor the motherboard temperature in real time. Once the temperature is too high, the system will immediately alarm and cut off the power supply to prevent accidents.

Connect in an orderly manner to ensure stability

Next is the connection of the power cord. Workers need to correctly connect the household AC power cord to the interface at the bottom of the motherboard and ensure that the connection is firm and reliable. At the same time, the charging pile gun head and the connecting cable assembly also need to be carefully connected to the top of the motherboard to ensure stable and unimpeded current transmission during the charging process.

Indicator lights and communication interface to improve user experience

In order to improve the user experience, the indicator lights on the mainboard need to be connected to the charging pile shell during the installation process. These indicator lights will indicate the different working states of the charging pile (such as charging, charging completed, etc.) through different colors of light, providing users with clear usage instructions. In addition, the communication interface of the mainboard needs to be connected to the network or other communication equipment to realize remote control, data transmission and other functions, further improving the intelligence level of the charging pile.

Charging pile module

Debug and test to ensure normal functions

The last step is the debugging and testing of the charging pile. Workers need to conduct a comprehensive functional inspection of the charging pile, including whether the plugging and unplugging of the charging pile gun head and the charging operation are normal. At the same time, necessary adjustments and corrections need to be made according to the test results to ensure that the charging pile reaches the best condition before it is put into use.

Charging pile module

The production and installation process of the charging pile main control board is a complex system engineering that integrates precision design, fine welding, strict quality inspection, manual assembly, and comprehensive testing. Every link needs to be refined and strictly controlled to ensure the stability and reliability of the charging pile main control board during use. It is with such a high-quality "heart" that new energy vehicle charging piles can provide more convenient and efficient charging services for the majority of car owners.
