One of the benefits of EVs, in terms of convenience to owners, is the ability to charge the onboard batteries in a few different ways. This makes it easier to power up no matter where the vehicle is. Standalone AC and DC charging stations can provide faster charges, with DC being the fastest. Onboard chargers, though slightly slower, are the most convenient because they only require a standard wall outlet to plug into. This article from Melexis explores efficient electronics design schematics for EV onboard charger circuits.

Onboard charger

The function of the onboard charger is to efficiently, reliably and safely convert AC electricity from the electrical grid (e.g. household plug) to DC electricity so it can be stored in the battery of the electrified vehicle (xEV). Melexis offers an integrated selection of components that perform exceptionally well in EV onboard charging applications.
