The importance of having an effective battery management system (BMS) for high power battery-powered applications especially in the electric vehicles and hybrid electric vehicles that are on the road today. However, due to inaccurate balancing of the battery cells, EV manufacturers are struggling to maintain and improve the reliability of the battery pack. Moreover, traditional BMSs lack functions which enable the battery data to be sent back to the manufacturer for monitoring and conducting long-term profiling of the EVs battery pack in order to ensure its reliability. This thesis aims to implement the Internet of Things concept into a BMS which will allow its data to be accessed online. Simple data processing was done in the cloud as a proof of concept that the raw data from the BMS could be processed in the cloud while providing almost real-time data for monitoring. Further implementation will be able to estimate the battery health based on the data received. The main challenge was building the voltage measurement circuit with off-the-shelf components, while still maintaining accuracy of the voltage readings and overcoming the high common-mode voltage of the battery pack.
