I have updated the schematic again. I got some input from mrbigh to put in a 5v regulator with some capacitors to protect the arduino. It...
Yeah, sorry, I'm not real knowledgeable when it comes to electronic schematics. :) I believe its now updated correctly. I have also expanded...
Yup, that is the plan. No need to worry about unbalancing as they'll only be on momentarily as the system shuts down. This should take less than...
Whoops, yes you are totally right. Those need to be split up and run to their corresponding pack negative terminals. Updated the diagram.
Well, pbui had a very good suggestion, get a diagram up. So, I did this over lunch. Please poke holes in it so I can improve it. :) The main...
The opto-isolator I'm using is the LTV-816. There are many out there that will work though. The two power source issue is only kind of an issue...
Yeah, thats pretty much how my setup is working. The opto-isolators are really just mini relays for logic controls (and are cheap). I don't have...
Three weeks go by very quickly. Tonight I got the additional circuit board all soldered up. It basically houses the opto isolators so no...
I'd be more concerned about the pack overcharging than the charger thinking the pack is fully charged.
As I said, I have an update on this project. I got it wired up enough to test out and see that its working. I'll definitely need to get it all...
Bleh, I just overcharged last night. I plugged in and forgot about it. A few hours later I went out and the pack was 57.7V, both balancer...
Looking good Dan. I'm quite interested to see how well this works out.
You pretty much have it. When plugged in for charging, the arduino will be powered by a wall wart power supply. However, when on the road, the...
I don't think the converter senses anything. It has a set voltage output and it just pumps that out period. As the voltage of the OEM pack nears...
Ah yes, so he can match weak and strong cells together. I forgot about that. Thanks.
Today was the first time I got to drive the car since installing the block heater and wooooooow does it work great. The coolant from the thermos...
Why are you balancing at the top if you are wanting to balance at the bottom?
Well, I'm back from vacation, and ready to finish this thing up! Today I took the time to reprogram the arduino for use with the celllogs. Using...
The PHEV is installed for those who haven't followed that decent sized thread. However, it has some major problems and needs some help in the...
The celllogs have arrived. They are very small which is kind of nice. The bad thing? They don't come with wiring harnesses for the batteries!...
