Battery Rejection Management

1. Function Overview

Battery Rejection Management is used to reactivate NG (defective) batteries produced during production, restoring them to normal production status and continuing to flow according to the process flow.

Main Functions:

• Battery Verification: Input battery barcode, the system verifies whether the battery meets the reactivation conditions
• Rejection Activation: Reactivate eligible NG batteries and restore them to normal production status

2. Term Explanation

Term	Definition
NG Battery	Batteries judged as defective during quality inspection in production
Rejection	Reactivate NG batteries to restore normal production
Battery Barcode	Unique identification number of the battery
Activation Status	Whether the battery is currently in a flowable production state
Tray	Production container carrying batteries
Batch	Production batch to which the battery belongs

Key Validation Rules:

Validation Item	Rule Description
Battery Existence	Each input battery barcode must exist in the system
Batch Consistency	All input batteries must belong to the same production batch
Tray Status	If the battery is bound to a tray, the tray cannot be in activated status
NG Status	The battery must have an NG flag; normal batteries cannot be rejected
Activation Status	The battery must currently be in inactive status; already activated batteries cannot be rejected

4. Operation Steps

4.1 Verify Battery

1. Go to [Production Monitoring] → [Battery Rejection Management]
2. Enter battery barcodes in the input box:
   • Method 1: Directly enter multiple battery barcodes in the input box, separated by commas
   • Method 2: Click the 📄 button on the right side of the input box, enter one battery barcode per line in the pop-up multi-line input box, click OK
3. Click the [Verify Data] button
4. The system validates the battery information, and upon passing, displays the battery details in the table below

Table Field Description:

Field	Description
Battery Barcode	Unique identification number of the battery
Batch	Production batch to which the battery belongs
Tray	Tray number bound to the battery
Serial Number	Production serial number of the battery
Activation Status	"Activated" or "Inactivated"
Grade Type	Grade classification of the battery
Grade	Grade information of the battery
Previous Process	Last completed process of the battery
Current Process	Next process for the battery to flow to

4.2 Execute Rejection Activation

1. After verification, verify the battery information in the table
2. Click the [Rejection Activation] button
3. The system pops up a confirmation prompt: "After confirmation, the battery will be activated. After activation, production can only start from the current process, and cannot redo the previous process"
4. Click OK to complete the rejection

[Important]:

• After rejection activation, the NG flag of the battery will be cleared, and the grade information will also be cleared
• After activation, the battery can only continue to flow from the current process and cannot return to the previous process
• This operation is irreversible. Please confirm before executing

5. Common Exception Prompts

Prompt Message	Cause	Handling Suggestion
Battery does not exist in BATTERY_MAP data	Battery barcode input error or not registered in the system	Check if the barcode is correct
Battery batch does not match the first one	Batteries from different batches were input	Ensure batteries from the same batch are rejected together
The tray bound to the battery is still activated	The tray containing the battery is still in production	Wait for the tray to complete before operating
The barcode must be inactive and an NG battery	The battery does not meet the rejection conditions	Only NG and inactive batteries can be rejected
The battery is already activated in the batch, no need to reactivate	The battery is already activated	No operation needed
The battery has no NG information, not an NG battery	The battery is a normal product	Normal batteries do not need rejection
