Title: Onboard charger (OBC Gen4.x) and DC-box (DCB 1.2 and DCB 2.0)

Description:

The main function of the component OBC is to convert the AC power from infrastructure to DC power to feed the vehicle HV battery. This component supports the monitoring functions like voltage and current measurements, temperature measurement, and plug detection.

The main function of DCB component is to transfer the High voltage upto 800V(Input) which stepdown to 400v and transfers to HV battery. This component supports the monitoring functions like voltage and current measurements, temperature measurement, and plug detection.

Responsibilities:

• Requirement analysis and test specification creation/updation.
• Test scripts creation/updation in Vteststudio.
• Test bench maintenance as EFK certified individual.
• Involved extensively in executing Regression testing to check quality of software.
• Working closely with IBM Doors and STARC in Test results updating and Bug reporting using Bug Life Cycle.
• Responsible for defect management with supplier to fix defects.
• Conducted root cause analysis on deviations during validation activities, enabling timely resolution of technical issues.
• Implemented continuous improvement initiatives for validation processes, leading to enhanced product quality and cost savings.

Project: CN-OEM (GEELY, ZOTYE, SAIC, etc)

Title: Advanced Driver Assistance Systems (ADAS)

Organization: Worked in Robert Bosch on deputation from L&T technology and services.

Description:
