Battery Traceability
1. Function Overview
Battery Traceability belongs to the Basic Traceability module of the MES system's Data Middle Platform. It is used to query battery information such as registration batch, tray location, activation status, good/NG judgment, etc., based on battery ID. Users can also access the battery detail page to view process set values and result parameter data for the battery across all processes.
Core Functions:
- Battery Information Query: Query basic information and production status of batteries by battery ID
- Process Tree Display: Intuitively display battery BOM material composition structure as an organizational tree
- Battery Detail View: View detailed process data (set values and result parameters) for each process
- Assembly Detail View: View material input (In) and output (Out) information for the current process
- Deactivate: Deactivate an activated battery, preventing it from continuing production
- Reactivate for Retrial: Reactivate an NG battery to allow it to continue production from the next process

4. Battery Details
4.1 Details Description
Click [Battery Details] button in the action column to enter the full-screen details page. The page is divided into two areas:
- Left - Process Tabs: Display all processes the battery has undergone as buttons
- Right - Process Data: Display detailed process data for the currently selected process
4.2 Operation Steps
- In the query result list, click [Battery Details] button for the target battery row
- System enters full-screen details page, left side shows process tab list
- First process tab is selected by default, right side shows data for that process
- Click other process tabs on the left to switch between different process data
- Click the back arrow in the upper left corner to exit the details page

Other Regular Process Data Items:
Display result parameters configured in the process model for that process. Each result parameter name is displayed with its actual collected value. When a result parameter is "defective" or "defective code", the system automatically converts the defective code to the corresponding defect reason description.
[Note] Capacity grade and grade information are not displayed for loading processes (DENGLU).
4.4 Process Data Search
In the "Item Name" header of the process data table, click the magnifying glass icon to expand the search input box. Enter keywords to quickly filter target data items. Click [Close] button to collapse the search box.
5. Deactivate
5.1 Function Description
Deactivate is used to set an activated battery to stopped status. After deactivation, the battery can no longer continue production. Use with caution.
5.2 Operation Steps
- In the query result list, find the target battery row (status is "Activated")
- Click [Deactivate] button in the action column
- System pops up confirmation dialog: "After confirmation, the battery will be deactivated and cannot continue production"
- Click [OK] to execute deactivation
- After successful operation, the battery's activation status becomes "Stopped"
[Note] [Deactivate] button only displays for batteries with status "Activated". [Note] If no other batteries in the tray are activated after deactivation, the tray will also be stopped.

6. Reactivate for Retrial
6.1 Function Description
Reactivate for retrial is used to reactivate a stopped battery that has been judged as NG, allowing it to continue production from the next process. After activation, the battery can only start from the next process and cannot re-execute the current process.
6.2 Operation Steps
- In the query result list, find the target battery row (status is "Stopped" and Good/NG is "NG")
- Click [Reactivate for Retrial] button in the action column
- System pops up confirmation dialog: "After activation, production can only start from the next process, cannot redo the current process"
- Click [OK] to execute reactivation
- After successful operation, the page automatically refreshes the query results
[Note] [Reactivate for Retrial] button only displays for batteries with status "Stopped" and judgment "NG".
