1. What are the common phenomena of bms failure?

Common symptoms of BMS (battery management system) failure may include the following aspects:

Insufficient battery or slow charging: BMS failure may cause insufficient battery or slow charging, which may be because the BMS cannot properly perform maintenance on the battery. management and monitoring, resulting in the battery not being fully charged or unable to exchange electrical energy.

Overheating or undercooling: BMS can also monitor the temperature of the battery. If the BMS fails, it may cause the battery to be overheated or undercooled. This may result in shortened battery life or even cause a hazard such as fire.

Inaccurate remaining power: BMS can also monitor the remaining battery power. If the BMS fails, it may cause the remaining power to be inaccurate, which may cause the battery to be turned off or charged at the appropriate time.

Unable to charge or discharge: If the BMS fails, the battery may not be able to charge or discharge, which may cause the battery to not work correctly or even provide power.

2. What are the common faults of brightness circuit?

Common circuit faults include the following:

1. Short circuit: A short circuit will blow the fuse of the lighting lamp, and the lighting lamp will burn out. In fact, it is caused by the collision of two wires in the socket.

2. Circuit break: A circuit break will cause all electrical appliances to be unable to operate normally. That is, the circuit is short, the lamp holder, the switch and the wire are broken, or the fuse is broken or the line entering the home is broken.

3. When installing the lines, each route was not installed properly, the bottom lane was messed up, and all the lines were connected together.

4. Load: The total power of the electrical appliance is too large, which is beyond the range that the circuit can bear. This will also cause a short circuit.

5. Poor contact: It means incorrect contact, poor contact in the hanging box, poor fuse contact, poor contact at the line connector, etc.

This will cause the lights to flicker on and off, and the electrical appliances will not work continuously.

3. Common faults in wiring harnesses?

Wire harness plays a key role in various applications such as automobiles and electronic equipment. Its common fault phenomena mainly include the following:

1. **Poor contact**: This is caused by the connector or other connecting parts Caused by contact problems, it may cause unstable or interrupted circuit signal transmission.

2. **Short circuit between wires**: Due to damage to the insulation layer of the wire harness or incorrect arrangement of wires, unexpected electrical connections may occur between different wires, resulting in a short circuit.

3. **Circuit Break**: If the wire in the wiring harness breaks for some reason, it will cause an open circuit and prevent the current from passing through.

4. **Ground (Ground) Fault**: When the wiring harness comes into improper contact with a metal part of the vehicle, it may cause a ground fault, which usually results in burned circuits or damage to electrical equipment.

5. **Natural aging or damage**: As the use time increases, the insulation layer of the wire harness may crack and the mechanical strength decreases, making the above-mentioned short circuits, open circuits and other problems prone to occur.

6. **Terminal oxidation or deformation**: Terminals are an important part of the wiring harness connection. If the terminals are oxidized or deformed, it will also lead to poor contact or short circuit.

7. **Human reasons**: For example, unreasonable installation location, incorrect wiring, damage to wiring harness components during maintenance, etc., may cause wiring harness failure.

8. **Electrical equipment failure**: Overload or short circuit of electrical equipment may also cause failure of the wiring harness connected to it.

In order to prevent and reduce the occurrence of these faults, it is recommended to take the following measures:

1. Regularly inspect and maintain the wiring harness and its connecting parts.

2. Make sure to use quality materials and correct assembly methods.

3. Avoid excessive bending or pressure on the wire harness.

4. Follow the manufacturer’s instructions for installation and repair of the wiring harness.

5. Repair or replace damaged parts promptly when a fault is detected.

In general, understanding these fault phenomena and preventive measures can help improve the efficiency of the wiring harness and extend its service life.
