AI Technical Summary

Problems solved by technology

When the battery is used in electric vehicles, the traditional welding method to couple the collector area of ​​the battery roll and the conductive sheet will not provide sufficient conductance (that is, the resistance value is too large)
Moreover, because the electric vehicle will vibrate when it is in motion, the welding place is easy to loose due to the vibration, resulting in poor contact
