Help,how to build a BMS with LTC6802-1 for 48V 100HA,

[qli029]

hi, there,

My supervisor asks me to build a BMS with LTC6802-1 for 48V 100HA, Li-Ion batttery pack (15 cells )
How can I start to work on it?

My background: I am a student. My major is power system engineering, with some power electronics knowledge.
i dont have any electronics design experience, never do DSP programming. BUT i have to learn them now.

my project is to integrate a modular based micro-grid, which include Wind turbine and solar power and a Li-Ion battery storage. they all connect to a 400V DC bus.
but the battery will be charged by 100~120V DC. all the sub-systems are built in the lab except the battery storage. Nobody work on the battery storage, so my supervisor pass it on me, poor me .

can some1 give me any idea? tech me how to start it from very beginning, (i read some literature for the pass two weeks, but no very helpful)

by the way, LTC6802-1 and DSP (TMS320F28335, TI chip) are available for me only.

If anyone have any literature that you think useful for my BMS-design, please email me: vincentli123@hotmail.com

thankz very much for any help.

Hi Vincent,
Did you read all the literature available here....http://www.linear.com/pc/productDetail.jsp?navId=H0,C1,C1003,C1037,C1134,P86662 ?

If you have no design experience, you're in for one heck of a project!
I found Linear's datasheet, design notes and the evaluation board's user guide to be invaluable and fairly clear on what was needed for a successful design. There's even a reference design schematic! It should be all you need to create a, let's say, 4S prototype that you can extend out to two LTC6802's handling your 15 cells at a later date.

Specifically what were you having trouble understanding?

Pardon my posting my response here but I'm a firm believer in the idea that if you post on a forum asking that others take the time to help you out that you should take the time to come back to that forum for the help and not request that we also go through the trouble of e-mailing it to you.

Good luck with the project!

hi john,

Thankz for the suggestion, i read the litterature from the website that you give me.
I will build a simple, prototype circuit to see how the chip perform, i think that will help me to understand what is going on,
I will come back with some questions later,

thankz everybody,
