Yield strength refers to the maximum stress a material can withstand before it begins to deform. In the context of EVs, yield strength is important for components such as the vehicle’s frame, battery casing, and suspension system, which must endure significant forces during everyday use or in the event of a collision. Materials with higher yield strength, such as high-strength steel or aluminum alloys, are often used in EVs to provide durability while keeping the vehicle lightweight, which is crucial for maximizing range and efficiency.
