1. Battery Management System (BMS) and Battery Pack
   Applied Materials: Conductive sponge, electromagnetic shielding plastic, conductive coating.

Scenario Description: Electromagnetic interference (EMI) between cells inside the battery pack needs to be prevented. Conductive sponge is used for sealing and shielding, while meeting lightweight requirements. For example, Kanglida's conductive sponge is applied in BMS modules of BYD, NIO and other vehicle models to shield interference between cells and ensure sealing performance.

The battery shell adopts conductive plastic or metal soft magnetic powder coating (such as Zircotec's ElectroHold EMI SHIELD), which realizes electromagnetic shielding and flame retardant functions, with a thickness of only 50μm, light weight and high temperature resistance.

2. High-Voltage Electric Drive System
   Applied Materials: Electromagnetic shielding plastic, carbon nanotube composite material.

Scenario Description: High-voltage components such as motor controller (MCU) and drive motor generate strong electromagnetic interference during operation. Qifu Plastic's electromagnetic shielding carbon fiber composite material is used in the shell of the electric drive system, replacing metal to achieve a 50% weight reduction, while meeting EMI shielding requirements (attenuation ≥ 60dB). Sinto metal soft magnetic powder is used in motor iron cores to reduce eddy current loss, improve power density, and act as an electromagnetic shielding material to reduce interference.

3. Vehicle-Mounted Electronics and Communication Modules
   Applied Materials: Conductive sponge, carbon nanotube coating.

Scenario Description: Precision electronic devices such as 5G T-BOX and ADAS sensors require high electromagnetic compatibility. Conductive sponge is used in radar and camera shells to shield external interference and adapt to vibration environments (e.g., Kanglida products can withstand temperatures from -40℃ to 150℃).

Carbon nanotube coating is applied in autonomous driving modules (such as the Faraday cage shield of Tesla Cybertruck) to prevent electromagnetic pulses (EMP) from affecting vehicle-mounted electronic systems.

4. High-Voltage Connectors and Harness Interfaces
   Applied Materials: Conductive sponge, conductive plastic.

Scenario Description: High-voltage connectors need to achieve both conductive sealing and electromagnetic shielding. Conductive sponge is used for interface sealing, with both elasticity and conductivity, preventing interference caused by loose plugging and unplugging.

Conductive plastic (such as carbon nanotube composite material) is used in connector shells, replacing traditional metal parts, reducing weight by 30% and meeting EMC standards.

5. Vehicle Body and Chassis Structure
   Applied Materials: Conductive aluminum foil, electromagnetic shielding coating.

Scenario Description: The body frame and chassis integrate electromagnetic shielding functions to prevent external electromagnetic interference from affecting in-vehicle systems. Conductive aluminum foil (such as Zircotec series) is used in body panels, with both lightweight and shielding performance.

Tesla Cybertruck adopts a Faraday cage cover made of carbon fiber-copper-nickel composite material to resist extreme electromagnetic environments.

6. Technical Trends and Advantages
   Lightweight: Conductive plastic replaces metal to reduce weight by 30%-50%.

Environmental Compliance: Water-based coatings and heavy metal-free materials meet RoHS standards.

Multifunctional Integration: Coatings simultaneously achieve flame retardancy, dielectric properties and EMI shielding (such as Zircotec OMNI SHIELD).
