Objective
To develop an intelligent and secure Charging Station that enables seamless vehicle-to-infrastructure (V2I) communication, ensuring reliable power transfer and compliance with global EV charging standards.
Solution & Approach
Requirement Analysis & Configuration
• Analysed OEM and industry standards such as ISO 15118 and IEC 61851.
• Configured AUTOSAR-based ECU Extracts using a third-party toolchain for communication and diagnostics.
• Defined data flow for charging session management and backend connectivity.
Network Management and Development
• Integrated CAN and Ethernet-based communication stacks for VCU–Charger interaction.
• Implemented real-time diagnostics, load management, and power optimization algorithms.
• Developed network management modules ensuring robustness under varied power conditions.
Memory and Bootloader Integration
• Integrated secure Flash Bootloader for Over-the-Air (OTA) software updates.
• Enabled firmware version control and rollback features for system reliability.
• Managed persistent data for charging parameters and event logs.
Security Enhancement
• Incorporated cryptographic libraries (HSM/SHE) and certificate-based authentication.
• Ensured end-to-end encrypted communication between charger and vehicle.
• Validated cybersecurity mechanisms against unauthorized access.
Testing and Validation
• Performed functional and communication testing using CANoe, CAPL, and HIL setups.
• Automated charge session and error-handling test cases using Python-based frameworks.
• Executed regression and interoperability testing across multiple ECU variants.
Impact
• Delivered a highly reliable and secure EV charging interface aligned with global standards.
• Reduced validation effort by 40% through automation and reusable test frameworks.
• Enhanced OTA update efficiency and cybersecurity compliance for EV ecosystem integration.
