Stand alone OBC/PDModule EV system Can 2015

[TrueSoln]

Just managed to get the charge light to come on
So think I have work out the CAN message to get the OBC live.
So I'm simulating the VCM with an UNO
And sending
14D, 1F2 and 50B message to it.

I'm still connected to Leaf Junction box and the battery management unit
Will look at logs now to work out if actual charging, and I will have to sort out cooling system for OBC before leave on two long ?

Does any one how hot the OBC (On board charger) and PDM (DC/DC Junction box/Power delivery module) would get during a standard charge done at home ?

ie how long could i leave on with out cooling it?

@TrueSoln, Very interesting information.
I want to test today too, but in the data stream I didn 't have id-14d. What is the syntax of this command?

The PDM can be used up to a few hundred watts uncooled. The charger same deal, maybe 250-500W uncooled for like 10 minutes. Efficiency is quite good, in excess of 85% for both, and there's a shit ton of aluminum to dissipate the few dozen watts it wastes.

Without a cooling system PDM Leaf 2013- 2017 heats up 10 minutes to 80-90 degrees Celsius and limits the current to 5 A, I personally checked on the car.

@ybpvin Reminder I'm using Gen1 the OBC is separate and in the boot of car, from message seen I think I recall that Message ID:1d4 may not be on Gen2.

PDM separate in Gen1 and if just using relay to charge and not on for DC conversion should not heat up too much.
But are working on what cooling paths for this also.

Not actual felt any heat but my charge did seem to stop working and I turned off.
Tried again in morning and was able to see charge light again.
I took some of the CAN message during this and will see if can see a fault code,
but Kenny and I think it might have a thermal cut off, but don't take that as fact unless any one can confirm.

I'm thinking that it go hot and stopped charging.
Working on water cooling now so can try again for longer.
Just trying to see what parts have about house to create water paths

@TrueSoln, I have a similar problem. The charger starts, there are no errors, but charging does not go ((

How do you know the charger starts ?
Is this a Gen1 or Gen2 and have you connected all the wires to the PDM (Junction box)
As when my starts to charge I can hear relays in PDM that come on.

Do you actual see the orange charge light come on one the charger module on wall ?

Did you ever get that counter added to your CAN code--i put an example code in the other thread that you were asking about. Do you have bypass wires for the HV interlocks? What are you using to negotiate the J1772 protocol with the EVSSE and the OBC?
Good luck and be safe,

We assembled the installation on the car, as shown in the video. PDM unit and engine. I put together a can-translator and connected to the installation. The high voltage battery is connected directly. We used Consult 3 to diagnose the errors. When PDM is healthy and working, a quiet whistle is heard. I can 't hear that sound.

I borrowed my native charging unit from the Nissan Leaf for the test. Wires are connected according to standard scheme. Can-data I recorded from a serviceable car. Edited and removed the ID that forms the engine. But battery charging is not going on.
