Custom High-Voltage Charging Harness for EV Tier 1
How Cablum helped a global OEM achieve IP67 sealing and 360° EMI shielding under an aggressive 8-week SOP timeline.
Key Outcomes
The Challenge
A Tier 1 supplier of EV charging systems required a high-voltage harness that could withstand extreme temperatures (-40°C to 105°C) and provide superior EMI shielding to prevent interference with sensitive vehicle electronics.
The project was further complicated by an aggressive, time-sensitive product launch schedule and the absolute requirement for production under strict IATF 16949 standards.
Our Engineering Solution
Our engineering team collaborated directly with the client's design engineers to propose a comprehensive solution:
Material Selection
Selected specialized XLPE wires & TE Connectors for high-temp resistance and a TPU overmold for durability.
Double Shielding
Engineered a double-layered shielding design (Al-foil + tinned copper braid) to provide 360° EMI protection.
The Results
-
Zero Defects Validation:
Passed 3000-hour thermal shock & vibration testing with zero failures.
-
On-Time Launch:
Met the critical Start of Production (SOP) deadline despite tight timelines.
-
IATF Compliance:
Full PPAP Level 3 documentation provided and approved on the first submission.
