What is the battery of an electric vehicle?
1 Answers
Currently, the batteries used in electric vehicles are: ternary lithium batteries, lithium iron phosphate batteries, and nickel-metal hydride batteries. Among them, nickel-metal hydride batteries are the most stable, lithium iron phosphate is the safest, and ternary lithium batteries have the highest capacity. Below is a detailed introduction: Ternary Lithium Battery: Excels in cooperation, offering the highest capacity for the same weight. However, its tightly packed components can lead to higher temperatures, so ternary lithium batteries have strict cooling requirements. To ensure safety, each battery cell must have a protective device. Lithium Iron Phosphate Battery: Favored by most automakers. Although its capacity per unit weight is not as high as that of ternary lithium batteries, it has excellent thermal stability, is less prone to overheating, and requires lower cooling component costs. Additionally, it offers advantages such as high energy density, compact size, long battery life, and good safety.
