Claim:
1. A wireless battery area network (WiBaAN) system for intelligent battery pack management comprising: a plurality of master battery management units (M-BMUs); a plurality of sensor battery management units (S-BMUs) each connected to at least one corresponding battery cell and at least one sensor configured to monitor said at least one corresponding battery cell, wherein each of said plurality of S-BMUs is connected to at least one of the plurality of M-BMUs by a first wireless mode; at least one top level battery management unit (T-BMU) configured to control the operations of the plurality of M-BMUs, wherein said at least one T-BMU is wirelessly connected to each the plurality of M-BMUs by a second wireless mode; at least one communications controller configured to estimate characteristics of a communication channel used by at least one of the first and second wireless modes, and to determine an optimal set of parameters which minimize noise and interference; and a secondary protection module wirelessly receiving at least one fault signal from at least one S-BMU from the plurality of S-BMUs; wherein at least a first S-BMU of the plurality of S-BMUs is wirelessly connected with at least one second S-BMU in a mesh network such that at least a first M-BMU of the plurality of M-BMUs is able to communicate with the first S-BMU via the second S-BMU.
