Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing charging circuit designs for electric vehicles require separate circuits for different regional standards, leading to high R&D, testing, and material management costs due to the need for multiple designs and materials to adapt to various national or regional standards.
Innovation Solution
A charging circuit board that integrates a first reserved area with a second resistor and a wake-up module, and a second reserved area with a wake-up switch module, allowing it to adapt to both Chinese/European and American/Japanese standards by replacing devices in these areas, enabling the sampling of slow charging pilot signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate circuits are designed for different regional charging standards, then each standard can be properly supported, but R&D costs, testing costs, and material management costs increase
Solution Approach 1:
The patent implements a universal charging circuit board that can support multiple regional charging standards (Chinese, European, North American, and Japanese standards) through a single unified design. The circuit board includes configurable components such as resistors, capacitors, and diodes that can be adjusted to match different standard requirements, eliminating the need for separate dedicated circuits for each region and reducing overall system complexity
Solution Approach 2:
The circuit board employs dynamic configuration capabilities where component values and circuit parameters can be changed based on the detected charging standard. The system includes detection circuits that identify the required standard and automatically adjust circuit parameters accordingly, allowing the same physical hardware to adapt its behavior to match different regional requirements without manual reconfiguration
2Adaptability or versatility
If multiple separate circuits are designed for different standards, then each standard is supported, but the number of materials increases leading to higher material management costs
Solution Approach 1:
The circuit board uses a unified set of components that can serve multiple functions across different standards. By using configurable resistors, capacitors, and diodes with adjustable parameters, the same physical materials can be used to support Chinese, European, North American, and Japanese standards, significantly reducing the total quantity of different materials required compared to having separate dedicated circuits for each standard
3Adaptability or versatility
If different circuits are designed to adapt to controllers for various standards, then each standard can be accommodated, but R&D and testing costs increase
Solution Approach 1:
The patent develops a single universal circuit board design that can be manufactured once and used across all regional standards, eliminating the need for multiple separate R&D projects and testing programs. The unified design reduces development time, manufacturing setup costs, and quality assurance expenses while maintaining full compatibility with Chinese, European, North American, and Japanese charging standards through configurable parameters
