This series will focus on the voltage and current monitoring solutions within Hybrid-Electric Vehicle/Electric Vehicle (HEV/EV) system – specifically on overcoming the challenges of high voltages and maintaining an isolation barrier. We will discuss specific op amp parameters to consider for monitoring within the on-board charger (OBC), battery management system (BMS), DC/DC converter, and inverter end-equipments. Part 1, covers system-level powertrain and other major end-equipment overviews.
