Let the 32700 battery no longer run "streaking" and introduce the battery pack processing process
A single battery cell cannot be used. Only by combining many 32700 battery together with a protective circuit and protective shell can it be used vertically. This is called a battery module.
A battery module is composed of many cells. Through strict screening, the cells with good consistency must be assembled into modular battery modules according to precise design, and single cell monitoring and management devices must be installed. In addition, each module has its own fixed identification code, so if there is a problem, the entire process can be traced.
The processing process from a simple battery cell to a battery pack is also quite complex and requires multiple processes. It is not at all simpler than the manufacturing process of 32700 battery.
1. Loading materials
The battery core is transferred to the designated position, and the robot automatically grabs it and sends it to the module assembly line.
2. Give the battery core a bath - plasma cleaning process
Clean the surface of each cell. Ion cleaning is used here to ensure that contaminants during the process do not adhere to the bottom of the 32700 battery.
Why use plasma cleaning technology? The reason is that plasma cleaning technology is the most thorough stripping cleaning method among cleaning methods. Its biggest advantage is that there is no waste liquid after cleaning. Its biggest feature is that it is very effective on metals, semiconductors, oxides and most polymers. Materials, etc. can be well solved and can achieve overall and partial cleaning as well as complex structures.
3. Combine the battery cores - apply glue to the battery cores
Before the battery core is assembled, the surface must be coated with glue. In addition to fixation, the purpose of glue can also be used for insulation and heat dissipation. High-precision gluing equipment and robots work together to apply glue at a set trajectory, while monitoring the quality of the glue in real time to ensure the quality of the glue and further improve the consistency of each set of different battery modules.
4. Build a home for the battery core - welding of end plates and side plates
Battery modules are mostly welded with aluminum end plates and side plates, and are solved by robot lamination and end plate and side plate welding.
5. Wire harness isolation board assembly
After the welding monitoring system accurately locates the welding position, it binds the material barcode of the wire harness isolation plate to the MES processing scheduling management system to generate a separate code for traceability. After coding, the wiring harness isolation board is automatically loaded into the module through a robot.
6. Complete the series and parallel connection of batteries - laser welding
Through automatic laser welding, the connection between the pole posts and the connecting piece is completed, and the battery series and parallel connection are realized.
7. The critical step before going offline - offline detection
Check the full performance of the module before going offline, including module voltage/resistance, battery cell voltage, withstand voltage detection, and insulation resistance detection. The standardized module design principle can be customized to match different models, and each module can also be installed in the best suitable space and predetermined position in the car.
Each battery pack contains several 32700 battery, integrated with connectors, controllers and cooling systems, and packaged in an aluminum shell. It is automatically tightened by bolts and connected by electrical connectors. Even if a failure occurs, only a single module needs to be replaced instead of the entire battery pack. The maintenance workload and risk are greatly reduced. To replace the module, only the cooling system needs to be dismantled. The solution does not involve other components.
