A closer look at minimizing AC charging losses: From the breaker to EV (Part 1)

Charged EVs

OBC: The onboard charger, a piece of power electronics equipment that converts the AC power from the grid to a DC voltage that is used to charge the battery (technically, it would make more sense to call this the charger). To summarize, while charging, current flows through various wires, cables, and connectors from the grid ?
