AI Technical Summary
Technical Problem
Existing DC cable harnesses in electric vehicles face issues with high heat generation, cost, and rigidity, while copper conductors are not optimal for flexibility and tolerance compensation.
Method used
The use of aluminum profiles for DC cables and multiple AC cables with copper for AC cables in a power transmission line assembly, along with a thermal paste to manage heat and flexibility, addresses these issues.
Benefits of technology
The solution provides a cost-effective, lightweight, and efficient charging system with improved heat dissipation and electromagnetic compatibility, reducing charging time and maintaining flexibility.
