Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Testing wireless charge transmit systems for electrified vehicles is challenging without an actual vehicle, as existing methods require a vehicle-mounted charge receive system, making troubleshooting and diagnostics complex and inconvenient.
Innovation Solution
A portable tester that mimics a vehicle-mounted charge receive system, equipped with a receiver coil, load bank, and radio frequency communication module, allowing it to wirelessly interface with the wireless charge transmit system, and featuring vertical and horizontal adjustment devices to replicate the positioning of a vehicle-mounted coil, enabling testing without an electrified vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vehicle-mounted charge receive system is used for testing, then the wireless charge transmit system can be tested, but the testing process becomes complex and inconvenient requiring actual electrified vehicles
Solution Approach 1:
The patent creates a portable tester that copies the essential functions of a vehicle-mounted charge receive system. The portable tester includes a receiver coil, load bank, and communication module that replicate the electrical and communication interfaces of an actual vehicle system, enabling testing without requiring a real electrified vehicle
Solution Approach 2:
The testing system is segmented into a self-contained portable tester unit that can be independently deployed. The tester separates the charging reception and testing functions from the vehicle itself, allowing the transmit system to be tested in isolation with a portable device rather than requiring integration with a complete vehicle system
2Ease of operation
If a portable tester is used to mimic the charge receive system, then testing can be done without an electrified vehicle, but the portable tester must replicate multiple vehicle functions
Solution Approach 1:
The portable tester is designed as a universal testing device that can interface with different wireless charge transmit systems. It combines multiple functions including power reception via receiver coil, power dissipation through load bank, wireless communication via RF module, and mechanical positioning through adjustment devices, making it adaptable to various testing scenarios without requiring vehicle-specific components
3Measurement precision
If coil positioning is precisely adjusted, then power transfer efficiency is optimized, but the positioning mechanism becomes more complex
Solution Approach 1:
The portable tester incorporates adjustable positioning mechanisms including vertical adjustment devices and horizontal adjustment devices that allow dynamic repositioning of the receiver coil. These mechanisms enable precise alignment with the transmit coil during testing while maintaining the ability to quickly adjust and reconfigure the positioning as needed
