Benifits of Heat Treatment for EV Battery Safety Ventings
The ev battery safety ventings are a key safety protection device for electric vehicles. It is mainly used to control the internal pressure of the battery and prevent dangerous accidents, such as explosions or fires due to overvoltage or overheating. To improve the performance and reliability of ev battery venting, they usually need to be heat treated.
Heat treatment refers to changing metal materials’ physical and chemical properties through heating and cooling to obtain certain organizational structures and properties.
Benifits of Heat Treatment for EV Battery Safety Ventings
Improve Strength and Hardness
The strength and hardness of ev battery safety vents can be improved through an appropriate heat treatment process. This ensures that the safety venting for ev battery packs can maintain their integrity and will not break or deform when subjected to external force or internal pressure, thereby effectively preventing safety issues such as leakage of internal materials in the battery or battery short circuit.
Improve Corrosion Resistance
Lithium-ion battery safety venting usually come into contact with chemicals in the battery, such as electrolytes, etc. These chemicals are often corrosive to a certain extent and can easily corrode metal materials, thereby reducing the performance of the safety vents. Through heat treatment, the corrosion resistance of the safety vents can be improved, its service life can be extended, and the reliability and safety of the battery can be improved.
Improve the Organizational Structure
Heat treatment can change the organizational form of metal materials and further improve their performance. Through a reasonable heat treatment process, internal defects and inclusions are removed, thereby improving its toughness and tensile strength and reducing the possibility of explosion or deformation caused by excessive internal pressure of the battery.
Improve weldability
The ev battery safety venting usually need to be welded to the battery cover to complete the battery assembly. Suppose the welding performance between the safety vents and other metal materials is not good. In that case, it will cause problems such as loose welding joints and leakage. Thus affecting the performance and safety of the battery. The weldability of the safety vents can be improved through appropriate heat treatment, the reliability of the welded joints can be improved, and the overall stability and safety of the battery can be enhanced.
As the models of new energy vehicles increases gradually,there are more and more categories of ev battery safety ventings. It is difficult for battery manufacturers to find safety vent valve manufacturers that can match them, which hinders the large-scale standardized production of power batteries. It is not conducive to reducing the cost of power batteries. Even after passing the test, verifying its feasibility will take a long time. For vehicle companies, it has increased the difficulty of matching and purchasing.
