  In modern systems that rely on the use of Battery Management Systems (BMS),
longevity and the re-use of battery packs have always been important topics of
discussion. These battery packs would be stored inside warehouses where they
would need to be properly monitored and configured before their re-integration
into the new systems. Traditional use of wired connections can be very
cumbersome, and sometimes even impossible, due to the outer layers and
packaging. To circumvent these issues, we propose an extension to the
conventional BMS design that incorporates the use of Near Field Communication
(NFC) for the purpose of wireless battery pack status readout. Additionally, to
ensure that these packs are only managed by authenticated devices and that the
data that is communicated with is protected against outside eavesdropping and
tampering, we present a solution in the form of a lightweight security layer on
top of the NFC protocol. To show the feasibility of our design, an accompanying
prototype has been implemented and evaluated.
