Please post any questions here about problems you are having with your BMS and more importantly help and advise in rectifying those faults. :wink:

Hello,

Let me introduce myself. I have been converting electric vehicles for about 6 years and have over dozen projects completed. I am in the process of building the Peter Perkins BMS system for two trucks and for several e-trikes.

I have some video of what I got going on. But I was looking for the hex files for watchdog, the slaveboard 12f683 and the masterboard 18f. I'm doing it in PIC.

I was using Isaac Thompson's modified program, but he changed the setting from LiFePO4 to LiCoO2, so now I wish for some nice clean versions.

I guess once I get those loaded up. I can report back here.

Again, thanks in advance!

Making another masterboard....

I was also trying to find a decent BOM list.

Looks like some of the parts on the masterboard are not required.
I am doing PIC not the PICaxe.

In particular

looks like c7, c9 are deleted.
what about c8, c11? are they required?

It says that r19 & r20 are not needed if using 12f683 pic for watchdog.
I soldier those in all ready, since I'm using 12f683 should I remove them?

Also is vr5 required?

what's the speaker requirements?

where do you buy the i2c temp sensor?

I can't remember the details of all your questions, you should be able to find them among the various topics in the BMS thread. Everything in here relates to the BMS project started by Peter. Some quick links;

A recent version of the Master http://www.batteryvehiclesociety.org.uk/bvsorguk/forums/download/file.php?id=145 from page 47 of the Old BMS software thread.

This picture of the master may help

There might be a few changes since this was taken, but it should be a start.

I'm on my way out the door right now, but have a good dig through the forums and load V30 onto your master and see if it works. Note that the hex will only work on the pic it was compiled for. Look in the source code (.txt) for details.
