In conventional Automotive Battery Monitoring Systems, measurements are carried out using "wired" solutions and data interchange between measuring unit and central unit takes place using isolated-CAN or isolated-SPI based communication channels. This arrangement comes with some drawbacks like considerable power dissipation, high cost, increased complexity of wiring harness and decreased accuracy. Here in this paper we present a qualitative analysis of different "wireless" communication protocols on the basis of parameters like Range, Power Consumption, Performance, Reliability and Simplicity. Implementation of wireless architecture will not only enable a monitoring system that is cheap and accurate but also result in decrease of the overall weight and size of the battery pack. A number of wireless protocols like ZigBee(IEEE 802.15.4), Bluetooth Low Energy(BLE5.0), Near Field Communication, Wi-Fi(IEEE 802.11) and Wi-Fi HaLow(IEEE 802.11ah) are considered as part of study in this paper.
