Patent number: 10811663Abstract: Methods and systems for welding a terminal of a battery cell to corresponding terminal tab or busbar are described using a magnet that causes the terminal and tab/busbar to be placed in physical contact. The terminal of a battery cell is aligned in contact with the tab/busbar by the force of a magnetic field. A welder, e.g., a laser welder, can then generate a laser weld beam to weld the terminal of the battery cell to the tab/busbar. Next, the laser weld beam is narrowed, reducing the first diameter to a smaller second diameter. Without touching the tab/busbar or terminal of the battery (which could affect the welding operation), the magnetic field can cause a force that brings the tab and terminal in contact during welding.Type: GrantFiled: May 12, 2017Date of Patent: October 20, 2020Assignee: NIO USA, Inc.Inventors: Austin L.
