EV Electric Vehicle Charging Cable 7 Core Customized EVVR National Standard

EV New Energy Electric Vehicle Cable (3, 4, 5, 6, 7 - core EVVR National Standard)

1. General Overview
   The EV new energy electric vehicle cable (EVVR national standard) with 3, 4, 5, 6, or 7 cores is a specialized cable designed to meet the demanding requirements of electric vehicle charging and power supply systems. It plays a crucial role in ensuring the safe and efficient transfer of electrical energy within electric vehicles.
2. Core Configuration
   • Number of Cores: Available in 3, 4, 5, 6, or 7 - core options. This variety allows the cable to be suitable for different electric vehicle models and electrical architectures. Each core has a specific function within the vehicle's electrical system, such as power transmission, control signal transmission, or grounding.
   • Core Design: The cores are carefully engineered to handle the electrical loads and signals required by the vehicle. They are usually made of high - quality conductive materials to ensure low resistance and efficient current flow.
3. Conductor Material
   • High - Quality Conductors: The cable's conductors are typically made of materials with excellent electrical conductivity, such as copper. Copper conductors provide reliable power transmission, minimizing power losses during operation. The quality of the conductors is crucial for the overall performance of the cable in the electric vehicle environment.
4. Insulation and Sheath
   • Insulation Quality: High - grade insulation materials are used to coat each core. These materials have excellent dielectric properties, effectively isolating the cores from each other and from the external environment. The insulation can withstand the high - voltage and current conditions within the electric vehicle without breakdown, ensuring electrical safety.
   • Sheath Material: The cable is protected by a durable sheath. The sheath material is designed to be resistant to abrasion, chemicals, and environmental factors such as heat, cold, and moisture. It safeguards the cable from physical damage during installation and operation within the vehicle.
5. Performance Characteristics
   • Electrical Performance: The EVVR cable demonstrates outstanding electrical performance. It has low electrical resistance in the conductors, enabling efficient power transfer for charging the vehicle's battery and powering its electrical components. The cable can also handle the high - current demands during fast - charging scenarios without overheating or voltage drops. The insulation and shielding (if applicable) ensure stable signal transmission for control systems within the vehicle.
   • Mechanical Performance: In terms of mechanical strength, the cable can endure the mechanical stresses within the vehicle. It can withstand bending, twisting, and vibrations that occur during normal vehicle operation. The combination of the core's flexibility and the strength of the sheath allows the cable to maintain its integrity under these mechanical forces.
   • Safety and Reliability: The cable complies with national standards for electric vehicle cables, ensuring its safety and reliability. It has features such as flame - retardant properties to prevent fire hazards in case of electrical faults. The cable's design and construction also minimize the risk of electrical leakage, short - circuits, and other safety - related issues.
6. Applications
   This EVVR national standard cable is widely used in electric vehicles. It is an essential component for connecting the battery to the charging system, as well as for powering various electrical systems within the vehicle, including the motor, control units, and auxiliary equipment. Its reliable performance and compliance with standards make it a key element in the development and operation of new energy electric vehicles.
