  In the last several years, wireless Battery Management Systems (BMS) have
slowly become a topic of interest from both academia and industry. It came from
a necessity derived from the increased production and use in different systems,
including the electrical vehicles. Wireless communication allows for a more
flexible and cost-efficient sensor installation in battery packs. However, many
wireless technologies, such as those that use the 2.4 GHz frequency band,
suffer from the interference limitations that need to be addressed. In this
paper we present an alternative approach to communication in BMS that relies on
the use of Near Field Communication (NFC) technology for battery sensor
readouts. Due to a vital concern over the counterfeited battery pack products,
security measures are also considered. To this end, we propose the use of an
effective, and easy to integrate, authentication schema that is supported by
the dedicated NFC devices. To test the usability of our design, a demonstrator
using the targeted devices was implemented and evaluated.
