In a particular embodiment, an apparatus is disclosed that includes a battery pack structure that includes a plurality of battery cells. The apparatus also includes wireless battery management system that includes a first wireless communication device, a second wireless communication device, and a radio frequency passive repeater. The radio frequency passive repeater includes a conductor cable, a first antenna at a first end of the conductor cable, and a second antenna at the second end of the conductor cable. In this example embodiment, the first antenna is located within a first wireless signal reception zone of the first wireless communication device and the second antenna is located within a second wireless signal reception zone of the second wireless communication device.

Communication in a wireless battery management system for a battery pack structure

A battery management system includes a primary module in wireless communication with a plurality of sensing, or secondary, modules over a range of frequencies within a predetermined frequency band. Each of the primary module and the sensing modules can be configured to transmit with an antenna polarization setting chosen from a plurality of polarization settings. Each of the sensing modules is configured to communicate with the primary with a predetermined one of its polarization settings for each channel. The primary module is also configured to communicate with a respective secondary module with a predetermined polarization setting for each channel.
