Hello,

My name is Ricky Gu. I was the guy behind the eBeetle cross Canada in 14 days back in summer 2010. See this article for more info: http://www.wired.com/autopia/2010/09/electrified-beetle-goes-coast-to-coast-in-canada/

Today I released the new revision of the same BMS that powered our vehicle across Canada to the open source community. It is released under Creative Commons Noncommercial Share-Alike license.

I know there are many experts on this forum and I know with your expertise, we can make a super awesome BMS and help drive the EV community forward.

To see the project, please go here: https://github.com/rickygu/openBMS

Last but not least, please do help spread the words on other forums and communities.
 
just to be absolutely sure im not jumping to conclusions, would that bms allow you to string as many a123-m1's together in whatever pattern you liked, within reason? what components and settings would need to change? would it allow a simple charger to be plugged in and the bms deals with the detail?
i have a 21 cell 72v (69.3?) pack in mind, but how would i string the bms together?
loving your work

each board can read 12 cells, so you have 2 bms boards, talking to one central micro controller. which can cut off charger/motor controller and display data.
 
i have no experience of the opensource or circuit board world, whats involved in contributing? can i just buy the built up board, download the code, wire up batts and test? if thats it, im totally interested. im not able to make my own boards, not enough soldering experience with cboards. whats the price likely to be for a board? when would it be available and is there a faq page i missed?
