Next-Generation Battery Management Systems (BMS) for Electric Mobility

Mohammed VI Polytechnic University (UM6P)

Doctoral research focused on next-generation battery management systems (BMS) for electric mobility. This work builds on previous LiFePO₄ battery modeling and advanced estimation of state of charge (SoC) and state of health (SoH), using an equivalent circuit model (ECM) with three resistor-capacitor pairs (3RC), an unscented Kalman filter (UKF), and a long short-term memory (LSTM) neural network. It also covers real-time embedded hardware and Internet of Things (IoT) telemetry for connected e-mobility.

Project: Smart BMS for Electric Mobility (Hardware, Algorithms & IoT Supervision)

  • Root-cause fix: Resolved a premature shutdown defect at 20% state of charge (SoC) and energy-gauge instability on electric scooters through a coordinated hardware, software, and process approach, supported by a safety-architecture-compliant digital twin aligned with International Electrotechnical Commission (IEC) 62133 and International Organization for Standardization (ISO) 26262 standards.
  • Estimation architecture: Designed a hybrid state-of-charge (SoC) estimation stack using an equivalent circuit model (ECM) with three resistor-capacitor pairs (3RC), an unscented Kalman filter (UKF), and a long short-term memory (LSTM) residual observer. It was validated through model-in-the-loop (MiL) simulation, with a root-mean-square error (RMSE) below 2%, and an instrumented hardware-in-the-loop (HiL) prototype.
  • Embedded hardware: Designed and routed a 16S STM32-based BMS board in Altium Designer, with bidirectional active balancing (LTC3300-1) and a finite-state machine (FSM) safety supervisor.
  • Industrial supervision: Built a real-time Message Queuing Telemetry Transport (MQTT) dashboard using a Representational State Transfer (REST) application programming interface (API) for production monitoring, battery-pack traceability, and key performance indicator (KPI) analysis.
