3 topics across all disciplines.
EV and hybrid topologies
How the engine, motor, battery and wheels are arranged in series, parallel and power-split hybrids, what changes in a pure battery vehicle, and why the layout decides what the vehicle is good at long before any component is sized.
High-voltage safety and isolation
Why an EV traction system is deliberately isolated from the body rather than earthed to it, how the interlock loop and isolation monitor work, and the shutdown sequence that has to be followed before anyone opens an orange cable.
Battery management systems
How a BMS estimates state of charge when it cannot measure it directly, what state of health really means, why cells drift apart and how balancing pulls them back, and what the thermal circuit is protecting.
