The embodiment of the invention provides an all-in-one power supply device, a power assembly and an electric vehicle. The all-in-one power supply device comprises a groove-shaped shell and a capacitor filtering integrated module. One capacitor filtering integrated module is used for integrating one bus capacitor, one EMC filtering assembly and two first connecting copper bars, and one bus capacitor and one EMC filtering assembly filter high-voltage direct current received by the two first connecting copper bars. The groove-shaped shell is further used for fixing a high-voltage connector, and the two first connecting copper bars are used for being directly and fixedly connected with two high-voltage lap joint copper bars of the high-voltage connector respectively and electrically connected with the positive electrode and the negative electrode of the power battery through the two high-voltage lap joint copper bars. According to the power supply device, the capacitor filtering integration module is directly in lap joint with the high-voltage connector, excessive cables and switching copper bars do not need to be used, the line layout in the power supply device is simplified, the assembly difficulty is reduced, and the integration level of the power supply device and deep fusion between electrical assemblies in the power supply device are improved.
本申请实施例提供一种多合一供电装置、动力总成及电动车,多合一供电装置包括槽形壳体和一个电容滤波集成模组。一个电容滤波集成模组用于集成一个母线电容、一个EMC滤波组件及两个第一连接铜排,一个母线电容和一个EMC滤波组件对两个第一连接铜排接收的高压直流电进行滤波。槽形壳体还用于固定一个高压连接器,两个第一连接铜排分别用于直接固定连接一个高压连接器的两个高压搭接铜排并通过两个高压搭接铜排电连接动力电池的正负极。通过一个电容滤波集成模组直接搭接高压连接器无需使用过多的线缆、转接铜排,简化了供电装置中线路布局、降低了装配难度,还有利于提高供电装置的集成度以及供电装置内电气组件之间的深度融合。
