I'm sorry to hear that your cellphone's charging port has stopped working. You are considering charging your battery by connecting wires from a USB Type-C charger directly to the battery and need to know which wires correspond to ground (negative) and positive.

Direct Answer to Your Question:

In a USB Type-C cable, the primary power wires are:

- VBUS (Positive Voltage): This wire carries the positive voltage, typically +5V.
- GND (Ground/Negative): This wire serves as the ground or negative connection.

However, identifying these wires in a USB Type-C cable is not straightforward due to the complexity of the USB Type-C standard and the lack of standardized color coding in the cables. Additionally, directly connecting a charger to a battery without proper regulation is highly dangerous and strongly discouraged.

Detailed Step-by-Step Problem Analysis:

1. Complexity of USB Type-C Wiring:

- Non-Standard Wire Colors: USB Type-C cables do not have a standardized color scheme for internal wires. Manufacturers may use different colors or even shielded wires, making it unreliable to identify wires based solely on color.

- Multiple Pins and Functions: USB Type-C connectors have 24 pins that handle power delivery, data transfer, and configuration. This includes:

- VBUS Pins: Multiple pins for positive voltage supply.
- GND Pins: Multiple ground pins.
- CC (Configuration Channel) Pins: Used for negotiating power delivery and establishing connections.
- Data Lines: For USB 2.0 and USB 3.0 data transmission.

2. Power Delivery Negotiation:

- Charging Protocols: USB Type-C chargers often utilize the USB Power Delivery (PD) protocol, which requires communication over the CC pins to negotiate voltage and current levels. Without this negotiation, the charger may not provide any power, or it might output a voltage unsuitable for your battery.

- Variable Voltage Output: USB PD chargers can supply voltages ranging from 5V up to 20V. Without proper negotiation, there is a risk of the charger supplying a voltage that could damage the battery.

3. Risks of Direct Battery Charging:

- Lithium-Ion Battery Sensitivity: Lithium-ion batteries require precise voltage and current control during charging, typically managed by the phone's internal charging circuitry.

- Bypassing Safety Mechanisms: Directly connecting a charger to the battery bypasses built-in safety features that prevent overcharging, overheating, and short circuits.

- Potential Hazards: Improper charging can lead to battery swelling, leakage, fire, or explosion.

Supporting Details and Explanations:

- Identification Challenges:

- Use of a Multimeter: To correctly identify the VBUS and GND wires, you would need to use a multimeter to test each wire. However, opening a USB-C cable and testing wires while connected to power poses significant safety risks, including short circuits and electric shock.

- Lack of Guarantee: Even with a multimeter, there is no guarantee that the charger will output power without the proper communication signals.

- Technical Limitations:

- Charger Activation: Some USB-C chargers do not activate power output until they detect a compatible device through the CC pins.

- Voltage Incompatibility: Providing an incorrect voltage to the battery can cause irreversible damage.

Recommended Actions:

1. Professional Repair of Charging Port:

- Expert Service: Have your cellphone's charging port repaired or replaced by a qualified technician. This is often a straightforward repair and ensures that your device remains safe to use.

2. External Battery Charger:

- Dedicated Charging Equipment: If your phone has a removable battery, consider using an external charger designed specifically for your battery model. These chargers include the necessary regulation and safety features.

3. Wireless Charging:

- Alternative Charging Method: If your phone supports wireless charging, using a compatible wireless charger is a safe and effective solution that bypasses the need for the charging port.

4. Data Backup and Device Replacement:

- Safeguard Your Data: If repair is not immediately possible, back up important data using cloud services or by connecting your phone to a computer if possible.

- Consider Replacement: If the device is old or repair costs are prohibitive, it may be time to consider replacing it.

Caveats and Additional Considerations:

- Avoid DIY Charging Solutions:

- Safety Risks: Attempting to charge the battery directly exposes you to significant risks, including electric shock, fire, and damage to the battery and phone.

- Warranty Voidance: Unauthorized modifications or repairs may void any existing warranties or insurance policies.

- Environmental Factors:

- Proper Disposal: If you decide to replace the battery or the device, ensure you dispose of the old battery properly, following local regulations for electronic waste.

- Further Assistance:

- Consult Professionals: If you're unsure about the repair process or need immediate access to your phone, consult with a professional repair service for guidance.

Conclusion:

Directly connecting wires from a USB Type-C charger to your cellphone battery is highly dangerous due to the complexities of USB Type-C power delivery and the sensitive nature of lithium-ion batteries. For your safety and to prevent damage to your device, I strongly recommend seeking professional repair services or using safer alternative charging methods such as wireless charging or an external battery charger.

Please prioritize safety over expediency. If you need further assistance or have questions about the repair process, feel free to ask.
