EV Charger Software Integrator

@Microlent

I can help with this integration end to end. I have experience working at the software–hardware boundary, including firmware update pipelines, remote diagnostics, and secure device management for embedded systems and charging infrastructure. I can design a reliable firmware update flow, integrate diagnostics for real-time and historical health monitoring, and ensure safe remote management without disrupting charging operations. My approach would be: • Review the existing charger firmware architecture and communication protocols • Implement or refine OTA firmware update mechanisms with rollback safety • Build diagnostics for fault codes, performance metrics, and remote health checks • Integrate secure remote management and logging for ongoing monitoring I’m comfortable working with embedded Node.js, Python, and backend services, and with common EV charging protocols and device communication patterns. I can share relevant examples and walk you through a clear technical plan before starting. Ready to discuss details and get started. Best, Jenifer

Requirement is not clear what exactly you are in need of. Can you explain in details whether you need to develop the firmware or it is just amendment to existing firmware. Need to discuss in details. I am from electronics background with over 25 years of programming experience in C, so can assist you with this nicelyThanks

KINDLY READ THROUGH MY PROPOSAL THIS IS WHAT I WILL DO DETAILED APPROACH - Design and implement a firmware update pipeline for your onboard EV chargers (local + remote), including versioning, integrity checks (hash/signature), safe rollback, and staged rollout to avoid bricking units. - Integrate diagnostics & remote management: health/status reporting, error codes, logs, and key measurements exposed via your preferred protocols (e.g. OCPP, REST, MQTT, Modbus/TCP), with clear APIs for your backend/portal. - Work closely with your hardware team to ensure robust handling of power loss, intermittent connectivity, and secure access (auth, TLS) during update and diagnostics operations. RELEVANT EXPERIENCE - Firmware and remote‑update mechanisms for EV / power electronics hardware (charge controllers, DC/DC, AC chargers). - Integration of diagnostics and management tools for field‑deployed devices. QUESTIONS - Which charger platform / MCU / OS are you using currently? - Do you already have a backend/portal for remote management, or should the API layer be defined from scratch? - Are you targeting a specific protocol (e.g. OCPP 1.6/2.0.1) for diagnostics and control?

Hi there, I’ve reviewed your project requirements and I’m confident I can help integrate firmware updates and diagnostic features for your onboard EV charger system. With a strong background in embedded systems, firmware development, and hardware–software integration, I’ve worked on several power electronics and smart charging projects involving diagnostics, remote management, and OTA firmware update mechanisms. My approach will include: Establishing a secure firmware update pipeline (via CAN, UART, or Ethernet, depending on your architecture). Implementing a diagnostic and fault reporting framework compatible with standard EV communication protocols. Ensuring robust error handling, rollback safety, and remote monitoring capability. If you’d like, send me more details on your current hardware platform and communication stack — I can outline a clear integration plan and timeline. Best regards, Samuel Tshibangu
