Information

Information on the Launch of the Tumanako projects can be found here: http://carrott.org/cgi-bin/twiki/view/ElectricSaker/Tumanako

Follow the Tumanako blog.

Please join our development mailing list: http://lists.sourceforge.net/lists/listinfo/tumanako-devel

If you are interested in helping out please send an email to the mailing list to introduce yourself. We are particularly interested in hearing from developers with C, C++ and Java experience. Electrical engineers and embedded developers are also welcome.

Projects

Battery Management System

The Tumanako EVD5 Battery Management system is a modular BMS capable of monitoring and balancing Lithium Ion cells. Each board monitors 5 cells and a central control computer controls the battery charger. Communication between nodes is via an RS485 bus. This BMS specifically measures bypassed current.

Also discussions and development of a LTC6802 based BMS are underway. It is simpler and cheaper and likely to provide everything one needs.

For more information and the continuing discussion around these options, please visit the BMS Pages.
