Here is a query from a friend of mine studying for a PhD in the smart grid area. Does anyone have any references or information on this topic? Others who might know more? As a preface, I don't really understand this stuff, so please feel free to reply with technical or dumbed down information. I will pass along verbatim. However, as I read the quote, the question is about EV CHARGERS (emphasis mine) and NOT EVSEs. I'm assuming that the person knows the difference between the two and is asking specifically about the CHARGER's ability to withstand frequency deviations. Thanks in advance.
I was looking for some information about the ability of EV chargers to withstand frequency deviations from their supply. I thought this would be a straightforward Google query, but I can't seem to turn up anything that answers what I'm looking for. The closest sources discuss the ability of smart chargers to use frequency as a signal to determine when to charge (e.g. smart grid applications). That's actually the reverse of what I want. I just want to confirm my assumption that EV chargers are relatively insensitive to frequency variations in the AC source, much like other power electronic interfaces.
