1. An apparatus comprising:
a battery pack structure that includes a plurality of battery cells grouped into one or more modules; and
a wireless battery management system that includes:
a first wireless communication device;
a second wireless communication device; wherein the second communication device is a module monitoring system, MMS, configured to monitor attributes of the battery cells in the one or more modules and transmit the monitored attributes to the first communication device; wherein the first communication device is a central controller that is configured to receive the monitored attributes from the MMS; and
a radio frequency (RF) passive repeater that includes:
a conductor cable; wherein the conductor cable includes a micro-strip;
a first antenna at a first end of the conductor cable; and
a second antenna at the second end of the conductor cable;
wherein 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.
