1.Core Materials for Electric Vehicles

As the global push for carbon neutrality accelerates, electric vehicles (EVs), as a symbol of green mobility, are becoming a vital force in driving energy transformation and promoting sustainable development.

Amid the rapid adoption of EVs, copper materials are standing out for their excellent electrical conductivity, thermal conductivity, and corrosion resistance. These superior properties enable copper to play a critical role in the EV “Three Electric Systems” — the battery, electric motor, and electronic control unit — significantly improving energy conversion efficiency, driving range, and durability. As a result, copper has become one of the core materials for optimizing the performance of these systems.

2.Copper Applications in the Three Electric Systems of Electric Vehicles

Battery: The "Super Artery" of Energy Transmission

Keywords: High Electrical Conductivity, Excellent Ductility, Superior Flexibility, Corrosion Resistance

In automotive battery systems, copper is primarily used in the production of battery electrodes, wiring, tabs, and thermal management components. Thanks to its excellent electrical conductivity, copper ensures efficient current transmission and minimizes energy loss, which in turn helps reduce battery heat generation. Additionally, copper's outstanding thermal conductivity significantly lowers the risk of thermal runaway and enhances battery stability in high-temperature environments, ensuring safe vehicle operation.

Electric Drive: The "Power Heart" of Efficient Propulsion

Keywords: Low Resistive Heat Loss, High Thermal Conductivity, High Mechanical Strength

The drive motor is the power core of electric vehicles, serving as the bridge for electromagnetic conversion through windings formed by multiple interconnected wires. Copper wire is the ideal material for these windings. During vehicle operation, motor windings must carry extremely high currents, and copper's excellent electrical conductivity enables efficient current transmission with minimal resistive loss, thereby enhancing motor efficiency.

Under extreme conditions such as sustained high-speed driving, copper's superior thermal conductivity helps dissipate heat generated during motor operation, preventing overheating. This ensures stable and reliable performance while reducing safety risks caused by excessive motor temperatures.

Electronic Control: The "Intelligent Brain" of Full-System Control

Keywords: Electromagnetic Interference Resistance, Fast Signal Transmission, Miniaturized Adaptation

The electronic control system is the core of intelligent control in vehicles, consisting of sensors, control units (MCUs), actuators, and circuits. The MCU, as the "brain" of the system, is responsible for regulating key functions such as battery management, motor speed, and energy recovery. It serves as the central hub that ensures the efficient collaboration of the Three Electric Systems.

In the electronic control system, copper is primarily used for the interconnection of various circuits, ensuring fast and accurate signal transmission, reducing electromagnetic interference, and enabling precise control of vehicle components. Additionally, copper's corrosion resistance makes it suitable for stable use in complex electrical environments, protecting delicate circuits from damage and enhancing system reliability. Its excellent plasticity and ductility also provide conditions for the integration and evolution of the control system. By optimizing the arrangement and combination of copper wiring, it can accommodate more compact circuit layouts.
