True Adam.. But the blocks are not "hot" (er in the sense of connected to any side of the power) are they? I can't remember his name BUT he did die ( of over excitement ) from PLAYING a gaming computer LOL !

You have water- cooled your controller right ( I have been lurking)

I have not water cooled my controller yet, but have designed the block needed to water cool it.

I am currently working on rebuilding my little milling machine to allow me more opportunity of milling PCB's and the water blocks. Once its back together, I have a 2 parts that I need to make for my father-in-laws car, then I plan to mill a water block for the current controller.

If somebody is willing to try it out, I would Love to see how it does.

Nice! Are you going to use a small pump and , say, an oil cooler radiator with fan to disperse the heat away?

I'm sure people will jump at the chance to try it !

AVR-CANbus

Hi All,

It would be greatly appreciated if the ReVolt Wiki could be updated as the open source Controller, BMS, Charger project files become available. Thanks !!!

I ran across this website Development and Prototype boards and tools for PIC AVR and MSP430 for an AVR-CANbus controller. They have a lot of nice AVR header and development controller PCB’s. The AVR-CAN development PCB uses a Microchip MCP2551 CANbus controller and a handful of discrete parts.

The CANbus interface to the AVR looks simple enough http://www.olimex.com/dev/images/AVR-CAN-sch.gif, I don’t know how complicated the changes to the Cougar firmware would be? But since Paul is using the CANbus on his new BMS and Charger it would be nice to have a version of the Non-Synchronous Cougar Controller that had a CANbus interface too.

A question that I have to the forum is: would the firmware for the Cougar Controller be compatible with, or could it be ported over to a larger AVR controller (AT90CAN128)? More memory, more I/O, etc….. I also like the idea of using a Daughter Microcontroller PCB. Having a standard ReVolt control board you could swap or upgrade the Daughter Microcontroller PCB with different Micro’s AVR, PIC, etc… of course it would need the different firmware too.

Comments ???

-Mark

Paul could i ask you to do a few mods to the "special" code again? Would you be able to increase the on delay to 10 secs and set it up so it cant energise during precharge?

I can try to post the schematics and parts list-inductor designs. I don't know the first thing about computors. It's open-source. I think it should have it's own thread-is there one now for us? Can someone open one? I also designed a speed control for the A/C compressor motor, and the 90 (?) amp erzatz alternator.

I'm going to TRY to post the 8 pages. There are rweally 3 inductors on one page-OK for me but to make it more clear, there are 4 inductors to make L1, and one has an extra few turns, then L2 is on the same page. 7 out of 8 pages are over the size limit. What do I do?

One solution would be to host the pictures or pdf. files in a web server service, like photobucket.com, no pun intended, and include a shortcut link in any thread for people to see them.
I will contact you soon fellow LIander.
