Embedded C Firmware for AC EV Charging Station (ISO 15118)
We are an Israeli company developing an AC electric vehicle (EV) charging station, and we are seeking an experienced embedded systems developer to implement the firmware in C for the station's controller.
The firmware should fully manage the operation of the AC charging station, including compliance with international EV charging standards.
Responsibilities:
Develop embedded firmware in C for an AC EV charging station.
Ensure full or partial implementation of ISO 15118 (Plug & Charge, communication protocols).
Support for IEC 61851 (control pilot signaling and basic safety requirements).
Interface with hardware components: relays, sensors, LEDs, HMI elements.
Implement safety monitoring (overcurrent, overvoltage, GFCI, etc.).
Integrate communication interfaces: UART, CAN, RS-485, or Ethernet.
Optional: backend integration via OCPP or equivalent
Requirements:
Strong experience in Embedded C programming.
Knowledge of EV charging communication protocols – especially ISO 15118 and IEC 61851.
Experience with microcontrollers (STM32, ESP32, etc.).
Familiarity with EVSE hardware and AC power systems.
Ability to read hardware schematics and integrate with PCB design team.
Good documentation and communication skills.
Deliverables:
Production-grade, well-documented firmware in C.
Integration guide and flashing instructions.
Assistance during system bring-up and testing.

99 1 day20 000 USDThis project sounds like a solid start for building a dependable and standards-friendly EV charger.
Before I get into the details and create a timeline, could you tell me how you’d like to handle the budget? Do you prefer setting a fixed price for each milestone, or would you rather go with hourly work?
Either way works for me. If you already have a budget range in mind, just share it so I can plan accordingly.
Looking forward to your reply.

We are basing our development on an open-source project by Everest (Linux Foundation Energy).
The selected developer will work on adapting and extending this codebase to match our hardware configuration and comply with standards such as ISO 15118 and IEC 61851. -
Hi, I'm interested but I have some questions.
How should testing be handled? Will you provide remote access to hardware, or do I need to emulate or purchase test boards?
-
Hi
We can provide a SW that emulates the EV behavior using USB-RS485 adaptor.
We of-course verify in our place that your output is working with the real HW
