Abstract: An inverter may include a housing having a body and a protruding rim extending from the body, wherein the protruding rim surrounds a cavity that extends through to the body. An inverter may include one or more electrical receptacles, wherein the one or more electrical receptacles are disposed within the cavity such that a portion of at least one of the one or more electrical receptacles extends above the protruding rim. An inverter may include a metal sheet, wherein the metal sheet is molded to an inner surface of the protruding rim such that the protruding rim extends past the metal sheet, and wherein the metal sheet circumferentially surrounds the cavity.

Abstract: An inverter assembly may include a housing with a base and side walls, wherein one of the side walls includes an opening extending through the wall, and wherein the side walls form a periphery around an interior of the housing. An inverter assembly may include a header with a body, the body having a first end and a second end, wherein the body further includes a flange disposed between the first end and the second end, and wherein a portion of the body extends through the opening such that the flange abuts the side wall. An inverter assembly may include a bracket positioned within the interior of the housing and coupled to the housing. An inverter assembly may include a choke that is fully enclosed in a circumferential direction, wherein the choke is positioned within the bracket and against an inner surface of the bracket facing the opening.

Abstract: Provided are methods for preparing a nickel-cobalt-aluminum precursor material and a cathode material with a gradient distribution of aluminum element. The precursor material and the cathode material based on the precursor material prepared by the methods are of sphere or sphere-like shapes in which the distribution of the aluminum element is changed in a gradient manner, and the particle size distribution is uniform. The synthesized material has a high tap density, is not sensitive to ambient carbon dioxide and moisture, and has a good processability, a high specific capacity and a good stability property.
