Abstract: An electrochemical apparatus, including a housing. The housing includes a main body part and a sealed part extending outward from an edge of the main body part. The main body part is configured to accommodate an electrode assembly. The sealed part includes a first outer edge, an outer arc edge, and a second outer edge. The outer arc edge connects the first outer edge and the second outer edge. The outer arc edge protrudes toward the main body part. A minimum curvature radius of the outer arc edge is rmin mm, satisfying: rmin?0.3, which can reduce the stress concentration at the outer arc edge of the sealed part under drop conditions, thereby reducing the risk of tear and damage to the sealed part of a battery under drop conditions, which otherwise causes safety accidents.

Each leg end extending from each of the layers has a common twist associated with the layer from which said leg extends.

Abstract: Embodiments of the disclosure provide a control circuit operable to control voltage delivery to a multi-component load. The control circuit is electronically coupled to a first component of the multi-component load. The control circuit is further electronically coupled to a second component of the multi-component load. The control circuit is operable to, responsive to an output voltage of a source, generate a second component voltage and provide the second component voltage to the second component of the multi-component load. A peak value of the second component voltage is less than the output voltage.

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: The present disclosure provides a battery piece feeding device and a soldering stringer, the battery piece feeding device is configured to lay battery pieces onto a soldering conveying device, the battery piece feeding device includes two picking mechanisms, both of the picking mechanisms are configured to alternately pick up the battery pieces from a battery piece picking position and lay the picked battery pieces onto the soldering conveying device. When one picking mechanism picks up the battery piece from the battery piece picking position, the other picking mechanism lays the picked battery piece onto the soldering conveying device. By arranging the two picking mechanisms and controlling the two picking mechanisms to alternately pick up the battery pieces from the battery piece picking position and lay the picked battery pieces onto the soldering conveying device, the battery piece feeding device greatly improves the battery piece feeding efficiency.

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.
