EV's can be charged with AC chargers or DC chargers. What's the difference? And why is DC charging so much faster? We answer these questions in this video.
There are inverters for AC-to-DC conversion too. After all, that's what happens in our vehicles when regenerative braking happens: the motor becomes an AC generator, and the traction inverter converts the AC electricity to DC for charging the batteries. A simple rectifier in a DC Fast Charger wouldn't really work because it can't control the DC output voltage. A DC charger needs to be able to adjust the voltage to (a) suit the voltage specs of the vehicle it's charging, and (b) adjust correctly for the batteries' state of charge, so the voltage actually changes during a charging session. An inverter is a complex, CPU-controlled device which can do all of this; a rectifier wouldn't be able to. You're right, though, that the inverters that most people are familiar with convert DC to AC, such as when you've got solar panels on your roof.

Great information. Thank you Dan for all the hard work you put in to these videos!!
Correction… A ‘rectifier’ converts AC to DC
An ‘inverter’ converts DC to AC
Great
Great info, but what's with the protection glasses 🤣. Do you expect the camera to fall on yoir face or what?
Is the term Converter used for the device turning AC into DC while Inverter from DC to AC? Or are the two words exactly the same?
I would say rectifier. :)
AC to DC ....its not Inverter.....its RECTIFIER
I think it is a rectifier not an inverter, converts from AC to DC.

Usually we call AC to DC “converter”, and DC to AC “inverter”.
And the AC to DC converter circuitry contains rectifiers.
Update: On September 18th of 2023, ZEV was delisted from NYSE.
