Wire Harness for Electric Vehicles

Components of Wire Harness for Electric Vehicles

Typically, a wire harness for electric vehicles consists of various components. As a crucial part of electric vehicles, these components must not only meet quality standards but also ensure safety, reliability, and performance in operational settings as required by electric vehicles. Since electric vehicles rely primarily on electric power for propulsion, they tend to have more components compared to traditional cars, usually including:

• Battery harness
• Power harness
• Control harness
• Lighting harness
• Power supply harness
• Instrument harness
• Audio harness
• Airbag harness

The various components of the wire harness for electric vehicles form a large harness assembly, which ensures the vehicle’s performance and normal operation.

Characteristics of Wire Harness for Electric Vehicles

Kaweei has strict standards for wire harnesses used in electric vehicles, requiring them to possess high-temperature resistance, low-temperature resistance, and electromagnetic interference protection. Since the electric drive system and electronic control system of electric vehicles generate significant amounts of heat and electromagnetic interference during operation, the wire harness for electric vehicles plays a crucial role in maintaining the normal operation of the vehicle. Therefore, it is essential that these harnesses can function effectively in both high and low-temperature environments for extended periods.

In addition to this, the wire harnesses produced by Kaweei also feature high flame retardant properties. By incorporating superior insulation materials into the harness, the risk of fire in the event of accidents or other failures is minimized, ensuring the safety of both the vehicle and its passengers. Overall, the characteristics of wire harnesses for electric vehicles typically encompass aspects such as safety, durability, reliability, and waterproofing.

Common Faults of Wire Harness for Electric Vehicles and Their Solutions

Kaweei has summarized the common faults that may occur during the daily use of wire harnesses for electric vehicles, along with their solutions, to help users quickly diagnose and resolve issues.

1. Wire Harness for Electric Vehicles Fractures

   Due to prolonged use or external damage, the wire harness for electric vehicles may fracture, causing circuit interruptions or short circuits. Solutions include repairing the fracture, typically through soldering or replacing connectors.

2. Insulation Wear of Wire Harness for Electric Vehicles

   The wear of the insulation layer can result in short circuits between the wire harnesses or with other vehicle components. The solution is to replace severely worn insulation parts to ensure the harness’s integrity.

3. Connector Failures in Wire Harness for Electric Vehicles

   Loose, oxidized, or damaged connectors in the wire harness can lead to circuit failures or poor signal transmission. Solutions involve cleaning the connectors, ensuring secure connections, and replacing connectors if necessary.

4. Wire Harness for Electric Vehicles Short Circuits

   Short circuits may arise from direct contact between wires or insulation damage. The method to resolve this includes locating the short circuit and repairing the broken circuit or replacing the damaged parts of the harness.

5. Moisture Damage to Wire Harness for Electric Vehicles

   Exposure to humid environments may cause electrical system failures. Solutions involve eliminating moisture from the environment, inspecting the harness for signs of dampness, and replacing damaged sections if needed.

6. Heat Damage to Wire Harness for Electric Vehicles

   Prolonged exposure to high temperatures can lead to aging, hardening, or melting of the harness’s insulation, resulting in circuit short circuits or interruptions. The solution is to prevent the harness from overheating and, if necessary, replace aged sections.

7. Mechanical Damage to Wire Harness for Electric Vehicles

   Impacts or vibrations from the vehicle may cause mechanical damage to the harness, such as crushing, tearing, or cutting. The resolution includes repairing the mechanical damage and replacing any damaged parts of the harness as needed.
