G11 epoxy sheet is widely used in new energy vehicles (especially electric vehicles and hybrid electric vehicles) due to its excellent thermal resistance, electrical insulation, mechanical strength, and dimensional stability. Its specific applications in NEVs include:

Insulation Components in Battery Systems

Battery Thermal Insulation and Insulation Plates: Installed between battery cells and enclosures, providing thermal isolation, fire resistance, electrical insulation, and mechanical support.

Cell Spacers: Used between battery cells in modules to prevent short circuits and enhance safety.

Battery Pack (PACK) Structural Components: Employed as top covers, support boards, or inner frames to secure cells and ensure mechanical stability.

Electrical Drive System Insulation Parts

Motor Internal Insulation Support: Used for slot wedges, coil supports, and insulation spacers in motors operating under high-temperature conditions.

Controller (MCU/VCU) Insulation Boards: Act as base or isolation layers for control boards to improve system safety.

Inverter & Power Module Thermal Insulation Boards: Installed between IGBT modules and heat sinks for electrical insulation and thermal protection.

High-Voltage Connections and Power Distribution Systems

HV Connector Insulation Brackets: G11’s high dielectric strength makes it ideal for use in busbar insulation pads and connector brackets.

DC-DC Converter Insulation Layers: Suitable for high-temperature, high-frequency conditions to enhance reliability and performance.

Structural Support & Lightweight Components

Non-metallic Lightweight Structural Parts in Compartments: With high rigidity and creep resistance, G11 can replace certain metal parts to help reduce vehicle weight.

Thermal Insulation Boards in Heat Management Systems: Used in battery thermal management to prevent heat transfer to sensitive areas.
