We are looking for a skilled Battery Management System Engineer with a solid understanding of BMS architecture, components, and safety features. The ideal candidate should have experience in failure analysis, problem-solving, and Li-Ion batteryassembly, including cylindrical, pouch, and prismatic cells, along with expertise in LV and HV battery system handling.
Experience with communication protocols such as RS485, Modbus, and CAN is essential, along with the ability to implement custom communication protocols provided by BMS manufacturers. The role also requires proficiency in preparing SOPs, work instructions, and quality checklists. Familiarity with battery chemistries like NMC and LiFePO4 and an understanding of their impact on BMS behavior are required. Knowledge of functional safety standards (e.g., ISO 26262) is a plus. Additionally, the ability to integrate BMS data into higher-level systems or dashboards for monitoring and control is crucial for this role.
Responsibilities
- Design, develop, and test embedded software and firmware for BMS applications.
- Integrate and configure BMS hardware including microcontrollers, sensors, and communication interfaces (CAN, UART, SPI, I2C).
- Implement state-of-charge (SOC), state-of-health (SOH), and cell balancing algorithms.
- Collaborate with hardware engineers to design PCB layouts and perform hardware-software co-validation.
- Work with cross-functional teams to ensure compliance with electrical, thermal, and mechanical battery requirements.
- Develop diagnostic tools and support root-cause analysis of field issues.
- Document software design, validation protocols, and change logs.
