Project : HASHTIC (Guided Autonomous Vehicle)

• A guided, autonomous pod that runs on rails. It uses a patented guiding mechanism to switch tracks that requires time-critical decision-making and monitoring.
• Worked on the central CAN network for inter-ECU communication.
• Worked on the control unit responsible for controlling and monitoring the track switch mechanism & braking
• Study, analysis, and design of project architecture.
• Design, development, debugging, and testing of preemptive measures and error-handling scenarios for track switching control unit.
• Study, design, development, debugging of Anti-lock Braking System
• Also worked on 380V power converter responsible for charging the vehicle's battery.
• Study, analysis, and design of project architecture.
• Design, development, debugging, and testing of preemptive measures and error-handling scenarios.

Project : 3.3KW, 7kW, 11kW & 22KW AC Chargers

• An IoT enabled AC charger complying to CCS and OCPP 1.6J standards communicating with an AWS server over WebSocket using WiFi Fallback 4G/BLE. It also features regulation over Control Pilot except 3.3 KW.
• Study, analysis and design of project architecture
• Design, development, debugging and testing of state machine
• Design, development, debugging and testing of pre-emptive measures and error handling scenarios.
• Study, analysis and development of IoT (WebSocket /4G) module
• Study and verification of compliance to OCPP 1.6J & CCS
