When talking about the performance of 200A energy storage connector, four points are generally indispensable, and the specific contents are as follows:

1. The yield strength of 200A energy storage connector is also called yield strength, which is the critical stress value of material yield. The so-called yield refers to the transition of metal from elastic state to elastic-plastic state non-uniformly after reaching a certain deformation stress. It marks the beginning of macroscopic plastic deformation. The influence of yield strength on 200A energy storage connector: the higher the yield strength of metal material, the greater the positive force at the end;

2. The tensile strength of 200A energy storage connector. When the material yields to a certain extent, due to the rearrangement of internal grains, its ability to resist deformation is improved again. At this time, although the deformation develops rapidly, it can only increase with the increase of stress until the stress reaches the maximum value. After that, the material's ability to resist deformation is significantly reduced, and a large plastic deformation occurs outside the weakest part. In addition, the cross section of the specimen shrinks rapidly, and necking occurs until it breaks. The maximum stress value before the material is tensilely fractured (the value corresponding to point b) is called the ultimate strength or tensile strength;

3. The elongation of the 200A energy storage connector refers to the percentage of the elongated length to the original length when the metal material is fractured by external force (tensile force);

4. The hardness of the 200A energy storage connector. The ability of a material to locally resist the pressure of a hard object on its surface is called hardness. The local resistance of a solid to the invasion of external objects is an indicator for comparing the softness and hardness of various materials. Because all metal materials of the 200A energy storage connector are extremely thin, they are measured by Vickers hardness (HV). The Vickers hardness (HV) is measured by pressing the material surface with a load of less than 120kg and a diamond square cone indenter with a vertex angle of 136°. The surface area of the material indentation pit is divided by the load value, which is the Vickers hardness value (HV). Hardness is an important parameter for selecting materials for 200A energy storage connectors.
