Laser welding of power batteries is a core process in battery manufacturing, directly impacting battery safety, sealing, and conductivity. Laser welding of power batteries spans the entire process from cell to module to pack, involving welding of positive and negative battery terminals, lithium battery safety vents, battery adapters, battery casing assembly, and module and pack
Research shows that lithium batteries will lose more power as the number of charging cycles increases, especially with high-power fast charging technology, which will cause the internal temperature of the battery to rise, so safety must be put first. For new energy vehicles, thermal runaway is the most serious and most frequent safety accident. How
In the prismatic battery battery safety system, the bursting discs(rupture disks) plays a crucial role as the “last line of defense”. Its performance is directly related to the safety level of the battery pack and even the entire vehicle. When selecting suppliers, automakers must not only stay at the level of meeting basic specifications and parameters, but
In the design of vehicle wiring harnesses that pursue high assembly, functional integration, and intelligent architecture, highly integrated connectors (taking into account both high-power power supply and small signal transmission) have become the mainstream choice. Selecting connectors of different grades according to application scenarios and functional requirements is the basis for ensuring that their lifespan
The role of Gas Sensors in Fire Robot Dogs Gas sensors play a vital role in fire robot dogs. They can detect and transmit data such as flammable/toxic gases in real time, providing a scientific basis for commanders to help them predict potential dangers in advance and develop reasonable rescue plans. The specific functions are
Precision sheet metal punching is a high-precision metal processing method. It is a process that uses the principle of plastic shearing. On a special press, a non-traditional precision punching die is used to make the material to be processed undergo plastic shear deformation under the action of huge pressure, thereby achieving material cutting. This method
Tesla’s decision to use cylindrical batteries as the power source for its electric vehicles was based on many considerations, and this choice has become one of the technical features of Tesla’s electric vehicles. Tesla’s Reasons for Choosing Cylindrical Batteries The reason for Tesla’s selection of cylindrical batteries is not single but the result of the
Press-fit terminals, as electronic connectors, are widely used in various electronic devices to achieve connections between circuits. In the design of press-fit connector pins, the design difference between blind-holes and through-holes has an important impact on their performance and application scenarios. The following is a detailed discussion of the difference between blind-holes and through-holes in
In the semiconductor industry, chip packaging and testing plays a vital role as a bridge between design and manufacturing. It not only affects the final performance of the chip but also directly affects the market competitiveness and cost-effectiveness of the product. The Significance of Chip Packaging and Testing Chip packaging and testing is the process
