EV On-Board Charger

What is an EV on-board charger?

The on-board charger(OBC) in electric vehicles converts alternating current from the grid into direct current to charge the vehicle’s traction battery. At the same time, it features an inverter function that allows for energy transfer from the battery back to the alternating current grid.
