Skills and results
What you will learn
You will understand in depth the e-mobility ecosystem from the perspective of high-voltage electrical architecture. You will analyze the difference between low-voltage networks (12/24/48 V) and the HV system of 400 V, 800 V, and emerging architectures. You will learn to read and build power diagrams of an electric vehicle, identifying all the high-voltage elements and their interaction with the rest of the subsystems. You will see how electrical architecture decisions impact range, performance, cost, safety, and maintainability.
You will master the main components of the HV system: high-voltage battery, contactors, precharge, traction inverters, DC-DC converters, AC/DC chargers, DC fast chargers, PTC heaters, electric HVAC compressors, and other auxiliary loads. You will study how they are interconnected in the high-voltage electrical architecture, what electrical requirements each one imposes (voltage, current, ramps, waveform quality), and how to ensure that the electric vehicle operates safely and efficiently in all operating modes.
You will delve into the design of HV wiring and high-voltage connectivity. You will learn to select cable sections, insulation types, shields, HV connectors, bulkheads, and fastening elements. You will see how the physical routing of HV wiring in the electric vehicle is defined, avoiding interference with sensitive areas, complying with bend radii, protecting against impacts, and ensuring correct behavior against EMC, vibrations, temperature, and humidity. You will understand why the design of HV wiring is critical in any high-voltage electrical architecture project.
You will specialize in high-voltage electrical safety. You will delve into insulation, creepage and clearance distances, protection against direct and indirect contact, insulation monitoring, fault management, and the design of HV system disconnection strategies in the event of an accident or failure. You will learn the principles of ISO 6469 and other applicable standards, translating those requirements into practical electrical architecture decisions: where to place contactors, how to divide the HV wiring, how to protect users and technicians from the high voltage of the electric vehicle.
You will develop competencies in the integration between the high-voltage electrical architecture and low-voltage networks. You will study the role of DC-DC converters, the coordination between the HV system and the 12/24/48 V system, safety logic, wake-up and shutdown modes, and communication with the BMS, inverters, and ECUs. You will learn to design a global electrical architecture in which the HV wiring and the low-voltage wiring coexist in a robust, safe, and optimized manner.
