What is an EV onboard charger?

An onboard charger (OBC) is an essential component in electric vehicles. It works by converting alternating current (AC power) from outlets to direct current (DC energy) which charges the battery.

How does an EV onboard charger work?

When an electric vehicle is plugged into a residential charger or public charging station, the onboard charger communicates with the charger to regulate the power, voltage and charging capacity to deliver a safe charge. The OBC also allows the EV to charge using a wide range of AC power sources with varying voltages and currents without needing specialised equipment.
