A Distributed Design Architecture for Li-ion Battery: Integration of COTS ICs, μ Cs and CAN Bus

In the proposed paper1,2 the modular and autonomous architecture concepts are deeply analyzed and applied to the design of an innovative Li-ion modular battery as test case. The single module integrates 6 terrestrial Li-Ion cells, the charge/discharge electronics and PIC microcontroller that supervises battery health and provides monitoring to an on-board computer. A Controller Area Network (CAN) bus connection is implemented in several battery modules and the communication protocol has been developed and tested.
