Abstract

The present invention refers to a power semiconductor device (1) for a vehicle, a battery system including the same, and the vehicle. The power semiconductor device (1) comprises: a power semiconductor (10); a base metal sheet (20); a flexible printed circuit board, PCB, (30) located between the base metal sheet (20) and the power semiconductor (10), wherein the power semiconductor (10) comprises a first power pad (12) on a side facing the flexible PCB (30); wherein the flexible PCB (30) comprises an electrically conductive pad (31), one side of the conductive pad (31) electrically connected to the first power pad (12) of the power semiconductor (10) and the opposite side of the conductive pad (31) electrically connected to the metal sheet (20).

Description

technical field [0001] The present invention relates to power semiconductor devices for vehicles. Furthermore, in another aspect, the present invention relates to a battery system including such a power semiconductor device and a vehicle having such a battery system. Background technique [0002] In recent years, vehicles using electric power as a source of mobile energy have been developed. An electric vehicle is an automobile powered by an electric motor using energy stored in a rechargeable battery. Electric vehicles may be powered solely by batteries, or may be in the form of hybrid vehicles powered, for example, by a gasoline generator. Additionally, vehicles may include a combination of electric motors and conventional internal combustion engines. Typically, an electric vehicle battery (EVB) or traction battery is a battery used to power the propulsion of a battery electric vehicle (BEV). Electric vehicle batteries are different from starter, lighting and ignition ...
