Responsibilities
- Design, code, debug and maintain application-layer and low-level software for BMS products, implementing core functions such as battery status monitoring, SOC/SOH estimation, fault protection and balancing control.
- Develop communication protocols between the BMS and other system components such as inverters, charging piles, EMS and display panels (e.g. CAN (CANopen, J1939), Modbus, RS485, Ethernet) to ensure real-time and reliable data exchange.
- Implement and optimize core battery pack algorithms, including high-precision SOC, SOH and power boundary (SOP) estimation, continuously improving accuracy and robustness.
- Design and implement fault diagnosis mechanisms and protection logic for over/under-voltage, over-current/short-circuit, over/under-temperature and insulation detection to ensure safe system operation.
- Produce technical documents such as software design specifications, communication protocol documents, test reports and fault analysis reports, and support the team in product certification.
Must Have
- Proficient in C++, with good programming habits and code-standard awareness.
- Familiar with mainstream MCU architectures such as ARM Cortex-M, with relevant embedded development experience.
- Understanding of battery operating principles and lithium-ion battery characteristics, and familiarity with basic BMS functional modules (voltage/current/temperature acquisition, balancing, protection, etc.).
- Familiar with the CAN bus and higher-layer protocols, with development experience in at least one mainstream communication protocol.
