BMS- Thermal Conductive Potting
PRODUCT DESCRIPTION
BMS (Battery Management System) – Thermal Conductive Potting is a solution that involves encapsulating electronic components in a thermally conductive potting compound to enhance heat dissipation and protection. This method plays a crucial role in maintaining the durability and efficiency of the BMS in demanding environments.
Product details
🔎 Key Functions of Thermal Conductive Potting
✅ Effective Heat Dissipation – High thermal conductivity potting compounds help transfer heat from electronic components to the environment, preventing overheating.
✅ Component Protection – Provides resistance against moisture, dust, and chemicals, prolonging the lifespan of BMS circuits.
✅ Vibration & Shock Absorption – Reduces mechanical stress, particularly in EVs and energy storage systems.
✅ Excellent Electrical Insulation – Prevents short circuits, ensuring the safety of the BMS system.
✅ Fire Resistance – Some potting compounds meet UL94-V0 standards, minimizing fire risks in case of thermal runaway.
🔹 Common Types of Thermal Conductive Potting Materials
🔸 Silicone Potting Compound – Excellent heat resistance, flexibility, and ideal for high-temperature environments.
🔸 Epoxy Potting Compound – High mechanical strength and chemical resistance but may be more brittle than silicone.
🔸 Polyurethane Potting Compound – Flexible, highly moisture-resistant, and well-suited for high-vibration conditions.
