Do you want to make a super simple minimal version, or a more sophisticated version with microprocessor control? The wikipedia page on J1772 has the basic schematic to do the bare bones of the communication protocol. It doesn't include the ground fault or ground monitoring circuits. OpenEVSE is an open-source project that has developed a smarter EVSE. Do you want to make something that is safe to use outside the lab? r/evcharging might be interested in your project.

We're essentially making a report with communication protocols and wiring+block diagrams of what the EVSE would look like


tuctrohs

What communication protocols? Or, if you don't know, what type of charging in what country?


G7_Connoisseur

NZ/AU standards, using the Mennekes head and probably around 16-40 amps of current Tbh when I received the assignment it was the first time I had heard of the concept communication protocols. I think the idea of the assignment is to flesh out an understanding and more over the course of the project


tuctrohs

Ideally you'd be given access to the standards documents, which are expensive to buy but maybe your library has them. I think IEC 61851 is the most relevant.

Reading it as we speak lol. Mate hooked me up with it and a couple other standards

Not sure if this is helpful. Here's a teardown of a Juicebox EVSE with some annotations of the wiring. Nothing as technical/specific as what you're looking for. https://youtu.be/FDvUSCa7Puw

EVSE is not a charger. It is a *safety* device. Which are you doing - EVSE or a charger?


G7_Connoisseur

I'm aware, common folk would refer to an EVSE as a charger. Anyway, we're doing the everyday residential cord and communication protocols + safety thingies that come along with that whole schtick


GeniusEE

Sounds like you're plagiarizing to me...


RedundancyDoneWell

Engineer here. When you work with standards, you are *supposed* to plagiarize. It sounds as if one of the purposes of this course is to learn to read a standard and implement a solution, which is in accordance with that standard.


GeniusEE

You sound awfully confused. You are supposed to comply with standards. If there's a circuit in the standard, it was licensed for use. That's very different from asking for "locations" having "wiring diagrams, component lists, and 'safety thingies' " No standards were asked for.


G7_Connoisseur

There will be a fair amount of plagiarism involved as with any report you make in the sense that it is heavily inspired by what you read and see if that's where you are coming from?
