Abstract
A rechargeable energy storage system and a method of manufacturing includes a battery pack having a battery cell module assembly with an interconnect board disposed between and physically connecting the battery cells with the cell monitoring unit, and a module cover at least partially enclosing the battery cells, the cell monitoring unit, and the interconnect board. The battery pack has relatively high and relatively low loss regions for radio frequency signal communication. A radio frequency manager is wirelessly connectable to the cell monitoring unit by radio frequency signal communication. A signal directing component is operable for transmitting and/or receiving a radio frequency signal between the cell monitoring unit and the radio frequency manager, is configured to direct the radio frequency signal to the relatively low loss region, and is integrated in one of the module cover, the interconnect board, or the radio frequency manager.
