Galvanic isolation enhances EV/HEV safety, performance and reliability.

The article focuses on the circuit assemblies of electric vehicle (EV) and hybrid electric vehicle (HEV) and galvanic isolation. It notes that the five main circuit assemblies of EV/HEV battery management systems include on-board charger, direct current (DC/DC) converter, and auxiliary inverter. Moreover, galvanic isolation insulates functional sections of electrical systems to avoid current flow between the sections while allowing energy or information to be exchanged between the sections.
