Protection against electric shock: Insulating materials prevent current leakage to the vehicle chassis, thus protecting occupants and responders.
Risk of fire and explosion: Lithium-ion batteries, commonly used in EVs, can be flammable. Good insulation reduces the risk of overheating and explosion.
02. Performance
Energy efficiency: Proper insulation minimizes unwanted current loss, improving overall battery efficiency.
Cell durability: Insulating materials protect cells from mechanical and chemical damage, prolonging battery life.
Thermal management: Insulation helps maintain a stable temperature, essential for cell operation and to prevent damage caused by extreme temperatures.
03. Reliability
Failure prevention: Effective insulation reduces the risk of sudden failures and extends battery life.
Long-term stability: High-quality insulating materials resist wear and degradation over time, ensuring consistent performance.
In short, electrical insulation in electric vehicle batteries is crucial to ensure safety, performance, durability and compliance with standards. Advances in insulating materials and thermal management technologies will continue to improve the reliability and efficiency of EVs, while reducing their environmental impact.
