Abstract
A battery module includes: a plurality of battery cells; a printed circuit board arranged within a short distance to the battery cells; a passive radio frequency identification tag; and a radio frequency receiver on the printed circuit board. The radio frequency identification tag is attached to at least one of the battery cells and is configured to measure a temperature of the at least one battery cell to which it is attached. The radio frequency identification tag is configured to harvest energy supplied by the radio frequency receiver and to wirelessly send temperature signals corresponding to the temperature of the at least one battery cell within an operating range limited to the short distance. The radio frequency receiver is configured to wirelessly supply energy to the radio frequency identification tag and to receive the temperature signal sent by the radio frequency identification tag.
