EV simulation

[CRBAman]

Hello!


Maybe somebody have circuit board for simulating different stated of the EV for EVSE?
Something like this:

That looks like one of OpenEVSE's products. What are you asking about it?

Yes, I want to make my own simulator. Its simply board, but I need a scheme

It's a very simple schematic...you just need a diode and a few resistors (you can add some switches to switch in various resistor values if you want to make it dynamically switchable). I was able to easily create one on a breadboard. See this page for more details:

The links are broken, but here's the really basic schematic for the various states:

And here's the "enhanced" one with the switch/jumper in place:

thank you so much! I've checked googlecode, but didnt find it! Thank you!

The second schematic is more accurate since you go by stages ( connect to charge).

The first is more convenient since you can use a toggle switch.

Chris has posted both first and second versions complete with eagle files on github.

If you just want to simulate charging with a ballpark value then a 820 ohm resistor in series with a 1N4148 will do the job.
