ACDC Module Terminal Arrangement for Charging System Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complex structure and assembly difficulties of ACDC and DCDC modules in charging systems for electric vehicles are exacerbated by long, disordered conducting wires that need to bypass multiple components, leading to increased complexity and assembly challenges.
Innovation Solution
The ACDC and DCDC modules are designed with terminals arranged in a length direction on the sidewalls of their housings, reducing wire length and neatness, and incorporating liquid cooling and floating structures to simplify the structure and assembly, while also enhancing reliability and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If terminals are arranged in the height direction of the housing, then the housing can accommodate more components, but the conducting wires become longer and more disordered
Solution Approach 1:
The patent changes the terminal arrangement from the height direction (thickness direction) to the length direction of the housing. This dimensional shift allows conducting wires to connect modules directly without bypassing terminal structures, reducing wire length and arrangement complexity while maintaining housing capacity
2Stability of the object's composition
If conducting wires bypass multiple components to connect modules, then all components can be included in the structure, but the wire length increases and arrangement becomes disordered
Solution Approach 1:
The terminals are pre-positioned on the housing sidewalls in the length direction, anticipating future wire routing needs. This preliminary arrangement eliminates the need for wires to bypass components, directly reducing wire length while maintaining complete structural integration
3Area of stationary object
If terminals are arranged in the height direction, then vertical space is utilized, but wire routing becomes more difficult and assembly harder
Solution Approach 1:
The patent transitions terminal arrangement from vertical (height) orientation to horizontal (length) orientation along the housing sidewall. This dimensional change simplifies wire routing paths and makes assembly easier, while the housing design still efficiently utilizes vertical space for component placement

AI summary
This application provides an ACDC module, a DCDC module, and a charging system. The ACDC module includes a housing, an AC input terminal, a DC output terminal, and a signal terminal. The housing includes a first sidewall. A part of the AC input terminal, a part of the DC output terminal, and a part of the signal terminal are all located inside the housing. The other part of the AC input terminal, the other part of the DC output terminal, and the other part of the signal terminal all pass through the first sidewall and extend out of the housing. The AC input terminal, the DC output terminal, and the signal terminal are arranged in a length direction of the first sidewall. When a conducting wire is arranged between a plurality of ACDC modules, a length of the conducting wire is short, and the conducting wire is arranged more neatly. When the ACDC module and the DCDC module are used in the charging system, a structure of the charging system is simplified.
