Automotive Electronics Manufacturing in Sri Lanka: Capabilities & Standards

Automotive Electronics Manufacturing in Sri Lanka: Capabilities & Standards

Automotive Electronics: A Growing Industry

The automotive industry is undergoing a fundamental transformation driven by electrification, autonomous driving, and connected vehicle technologies. The average modern vehicle contains over $3,000 worth of electronic content — from engine management and safety systems to infotainment and advanced driver assistance (ADAS). This growth creates enormous demand for reliable automotive electronics manufacturing and cable harness assembly.

EV Cable Harness Manufacturing

Electric vehicles require fundamentally different cable harness architectures compared to internal combustion vehicles. EV cable harnesses must handle high-voltage power distribution (400V-800V), battery management system interconnections, and charging infrastructure connectivity — all while meeting stringent safety and EMI shielding requirements.

TOS Lanka's automotive harnessing division manufactures EV cable harnesses including battery pack interconnects, motor controller wiring, and on-board charger harnesses. Every EV harness assembly undergoes 100% high-voltage continuity testing and insulation resistance verification before shipment to global automotive OEMs.
