Key Responsibilities Component Assembly & Integration: Hand-assemble and install critical EV aggregates, including Motor Controllers, Battery Management Systems (BMS), DC-DC converters, and traction motors (BLDC/PMSM).Wiring Harness Management: Lay out, route, and connect low-voltage and high-voltage wiring harnesses. Ensure correct crimping, terminal torque, and high-grade insulation according to engineering drawings.Testing & Quality Control: Perform End-of-Line (EOL) testing on battery modules and powertrain components using digital multimeters, oscilloscopes, and insulation testers (Megger testing).Software Flashing & Calibration: Flash firmware, upload vehicle-control software, and calibrate parameters using specific automotive diagnostic scanning tools.Troubleshooting & Rework: Diagnose assembly-line faults, communication errors (CAN bus/LIN bus issues), and short circuits. Perform component-level rework or repairs as directed. High-Voltage Safety Adherence: Strictly follow established safety protocols, including the mandatory use of insulated tools, ESD (Electrostatic Discharge) workstations, and high-voltage PPE. Line Documentation: Maintain production logs, log diagnostic fault codes, and complete quality checklists accurately for every batch.
