Abstract: The disclosure provides a strap pulling device, the strap pulling device comprises a cutter mechanism, a first strap pulling mechanism and a second strap pulling mechanism. The first strap pulling mechanism and the second strap pulling mechanism are configured to alternately clamp a strap at a pulling position located upstream of a cutting position and pull the strap to a transfer position located downstream the cutting position. When the first strap pulling mechanism pulls the clamped strap to the transfer position, the second strap pulling mechanism clamps the strap at the pulling position, the cutter mechanism cuts the strap at the cutting position to acquire a strap segment. When the second strap pulling mechanism pulls the clamped strap to the transfer position, the first strap pulling mechanism clamps the strap at the pulling position, the cutter mechanism cuts the strap at the cutting position to acquire a strap segment.

Abstract: An electrochemical apparatus includes a housing having a cavity and including a wall, where the wall is provided with a stress-weak zone. In this application, the stress-weak zone arranged on the wall of the housing of the electrochemical apparatus is a weak part of the housing. When the electrochemical apparatus generates gas under conditions such as short circuit, high temperature, and overcharge, a pressure inside the housing increases. Under the action of the pressure, the stress-weak zone can form an opening, and the opening allows the inner cavity of the housing to communicate with the external environment in which the electrochemical apparatus is located, to discharge the gas in the inner cavity of the housing, thereby reducing risks of expansion, deformation, or even explosion of the electrochemical apparatus caused by gas generation inside the electrochemical apparatus, and improving safety of the electrochemical apparatus.

Abstract: A stator for an electric machine comprises a stator core and a winding positioned on the stator core. The stator core includes a plurality of teeth defining a plurality of slots. The winding is comprised of a plurality of segmented conductors connected together to provide a plurality of parallel paths per phase for the winding, each conductor comprising (i) an end loop provided on a crown end of the stator core, (ii) two legs extending through the slots, and (iii) two leg ends extending out of the slots on a connection end of the stator core, each leg end having a twist portion. The legs of the conductors are arranged in layers in the slots, wherein the layers include a total number of layers (L), L being greater than five and L/2 being an odd whole number. Each leg end extending from each of the layers has a common twist associated with the layer from which said leg extends.
