Step 1 Install the BMS and Accessories
Firstly we need to fix the BMS On the board of the cover ,in addtion. there is some other accessories need to be install in addvance
Step 2 Lifepo4 Cell Sorting and Pairing
firstly We will test the capacity . Voltage and Inner resistance of each cell, according to the related standard like capacity difference within 2Ah. same voltage and the inner resistance within 0.02 to combined with the battery .then we need for each pack .like 4pcs . 8pcs or 16pcs .make sure they will have the high consistence when they work together . It will guarantee the whole pack work effectively and fluently with long life
Step3 Assembled Module
We will connect the required batteries (sorted according to specifications) by connecting their positive and negative terminals, and use corresponding specifications connecting strips to link them. Additionally, we will secure them with insulating materials around the perimeter for further fixation, ensuring they remain tightly bound and will not loosen during use
Step4 Scan and Archive
In this step ,Scan all the barcode to get the battery actual data for each pack, It is very important and necessary . we will keep this data as our history record so that can we can track it for each cell.in future , if there is any problem of the pack we can check the original data for repair . It is one step of our quality control .
Step5 Put The Module into box
after the previous , then we Put the whole Module into box based on the wall of the BMS and accessory then add the bottom of the box , and fix them
Step6 polarity detection
In this step we will Check whether each pole post is connected with correct polarity (positive/negative) to prevent errors during assembly that could lead to failure in the entire Parker manufacturing process
Step7 Electrode Post Cleaning
we will do this step to Ensure that the surface of each electrode post is smooth and clean to prevent issues, such as omissions or displacement during the laser welding process.
Step8 Linker Sheet Inspection
we will Check that each linker sheet is properly connected and free of omissions, and place them in the correct positions to facilitate the subsequent laser welding process
Step9 Laser Welding
then we will Use a computer-controlled fully automatic laser welding machine to perform welding
Step10 Welding Point Inspection
In this step we will Inspect each welding point to ensure secure bonding, checking for any脱落 or missed pole pillars. Install PCBA retaining strips on the welded module if no errors are found to ensure insulation and safety.
Step11 Data Line Welding
Based on the previous Laser weld pre-positioned data collection lines to ensure firm fixation and safety
Step12 bundle insert gray ribbon cables
after that .we will test whether various cable assemblies function properly. If everything is normal, organize and bundle them neatly for aesthetics and install the ribbon cables.
Step13 Install power cables
then we will Laser weld pre-positioned data collection lines to ensure firm fixation and safety
Step14 ATE Testing
After previous step , we will Use dedicated equipment to test battery charging/discharging functionality, checking for overcurrent, overvoltage, undervoltage conditions.
Step15 Install upper cover
After testing is complete, install the entire Parker’s upper cover, completing the finished product.
Step16 Aging Test
Then we will Conduct further aging tests on the finished product using specialized equipment to verify capacity retention, internal resistance changes, voltage consistency, temperature control, etc.
Step17 Packaging
finally we will Package the finished product in paper or wooden boxes based on specifications for safe shipping
