# 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 |
