The relay is to short out the pre-charge resistors when pre-charge is over.shuma89 said:I also see on the plate 3 big resistors 1 black relay and 1 big 310v 1.0 mf capacitor. I want to know what is function of relay and also want to see the schematic of them.
While you may well be able to replace the input diodes with a bridge rectifier off the Waffle Plate™, I suspect that replacing the IGBTs will be impractical. You'll likely have to find a second-hand plate from another charrger, or perhaps a whole charrger from a wrecker. It's not clear to me that the iMiev Waffle Plate™ will be similar enough to the Nissan one.Where can i see the waffle plate's igbt models?
I've never hear of a source for a new plate.I also want to know, if it possible where can anyone buy the waffle plate a new one.
Someone did replace just some small capacitors in one; see the iMiev topic, near the end. For example, here. But that was a pretty mild repair compared with replacing IGBTs.Anyone have repaired the waffle plate?

There isn't a good schematic for the Nissan OBC, but it is fairly similar to the Mitsubishi iMiEV OBC, so you can use the schematic of the pre-charge circuit here as a guide. There is an index on page one of that topic to guide you to other topics that may be of interest.

[edit]
That's why i asked about your experience level with electronics repairs--it takes a vacuum desoldering station to remove the 72 solder joints on the waffle plate.

SageBrush said:I'm encountering intermittent L2 charging problems as of yesterday. I'm just at the beginning of trouble-shooting but I'd like to at least know how to remove the charger port to have a good look at it if needed. A small voice is telling me to look for a gnawed wire.
Does anybody have a link to a good video of the steps involved ?
nlspace said:This schematic is on page 1 of my OBC troubleshooting thread. The black epoxy on the waffle plate is very difficult to remove, let me know if you find a way to do it. The part number of the 600V 20A diodes is Shindengen DF20L60; The IGBTs were identified but i can't remember just now, will have to get back to you.
