Use this BMS for a Powerwall like battery #1

Could this BMS be used in an application like the Tesla Powerwall?

evanmj commented 7 years ago

I believe the tesla power wall has a BMS / charge system onboard already. From the little bit I know about his project (I've just discovered it), the answer to your question is yes... if you had a bunch of lithium cells and needed to balance and maintain them, this system would do it. You could in theory pull the BMS out of the tesla power wall and put in your own, but that would probably not make sense. A BMS for a car and for a 'powerwall' are the same essentially. The batteries don't know or care what they are supplying, as long as they are kept balanced and happy. :)

Thanks. Yea, I meant to create something like a power wall. Not use this BMS in an actual Tesla Powerwall. :)

Hey how far were you able to get with this? Looking at building something similar.

joanbarros commented 5 years ago

I've not been able to dedicate much resources to this (time and money). Hopefully, I'll be able to in the following months... Although no hard dates yet... 😕

No problem I'm looking at several different bms systems currently designing the enclosure. Thinking a modular array with bays that allow for use of lead acid batteries and lithium ion similar to server hard drive bays.

I have also done some small research about DIY powerwall BMS options. Sadly, I have not found any good and open modular BMS like this project. If anyone finds one, or can improve this project, it would be awesome!

For non-modular FOSS BMS, I have used Electrodacus smbs120 and works fine at least in my test-bench. But it is not modular in the sense that this project aims to be.

In projects like this and that in 3d printing I used to forget that the other open source contributors are still learning as I am. Many know more but they got to their minimum viable product so stopped.
