A Wireless battery area network permits the wirelessly monitoring and controlling of individual batteries within large-scale battery applications. The system automatically configures its wireless nodes in the network and provides for the linking of a plurality of batteries (10) to a master battery management unit (M-BMU) (100) by establishing a wireless battery area network within a battery pack that include slave units (S-BMU) (210). The entire system may also be controlled by a top level battery management unit (T-BMU) (510). The system and method allows for the monitoring of voltage, current, temperature, or impedance of individual batteries and for the balancing or bypassing of a battery. A communications controller allows for optimization of wireless communications parameters and beamforming.
A wireless battery area network (WiBaAN) system for intelligent battery pack management comprising:
The system of claim 3 further comprising a secondary protection module configured to wirelessly receive at least one fault signal from at least one S-BMU from the plurality of S-BMUs, wherein the secondary protection module is configured to wirelessly receive the at least one fault signal when at least one M-BMU from the plurality of M-BMUs is not responsive to the at least one fault signal from the at least one S-BMU from the plurality of S-BMUs.
The system of claim 3 wherein the plurality of battery cells are housed in a metal case and wherein the plurality of S-BMUs is mounted directly on said metal case.
The system of claim 3 wherein each of the plurality of S-BMUs is wirelessly connected with at least one other S-BMU in a mesh network such that each of the plurality M-BMUs is able to communicate with a first S-BMU by communicating with a second S-BMU that is in communication with the first S-BMU.
