Skills and results
What you will learn
You will understand the central role of the on-board charger within the electric vehicle and e-mobility ecosystem: power paths from the grid to the battery, interaction with the BMS, coordination with the DC-DC converter and the traction inverter. You will study the differences between unidirectional on-board chargers and bidirectional chargers, and you will see how V2G, V2H, and V2X functions are changing the role of the electric car, transforming it from a mere load into an energy resource connected to the grid. You will be able to read and build high-level schematics of OBC chargers and bidirectional charging systems.
You will master the fundamentals of power electronics applied to on-board chargers and bidirectional chargers: AC-DC conversion, power factor correction (PFC), isolated DC-DC topologies, sizing of magnetics, filters, and key components. You will understand how to choose the appropriate on-board charger topology based on power, battery voltage, grid requirements, and the need or not for bidirectional charging. You will learn to compare architectures and to argue technical decisions based on efficiency, power density, and cost criteria.
You will delve into modern power devices (IGBT, Si MOSFET, SiC, and GaN) specific to on-board chargers and bidirectional chargers. You will analyze how SiC and GaN technologies enable more compact, lighter, and more efficient OBCs, both in charging mode and in V2G/V2H mode. You will learn to read datasheets, to select devices based on voltages, currents, and switching, and to integrate them into specific bidirectional on-board charger topologies.
You will specialize in control and firmware for on-board and bidirectional chargers. You will study PFC control, current and voltage loops, modulation of isolated DC-DC converters, power limit management and protection, as well as control strategies specific to bidirectional charging and V2G, V2H, and V2X modes. You will see how these algorithms are implemented in DSPs, microcontrollers, or FPGAs, moving from simulation to the real code that governs an on-board charger and a bidirectional charger.
You will develop competencies in on-board charger integration and bidirectional chargers in the electric vehicle: connection to the HV system, coordination with the BMS, grounding architecture and EMC, thermal management, protection, insulation and safety requirements. You will understand how the OBC communicates with the rest of the vehicle through communication buses, how bidirectional charging is coordinated with the battery state, and how the charger’s impact on the HV-LV electrical architecture is managed.
