A Critical Approach Towards a Smarter Battery Management System for Electric Vehicle

The most basic component in the Electric Vehicle is the Battery, that acts as a main source of energy and gives it mobility which is sustainable. In electric vehicles, the technology which is highly acknowledged and used for energy storage is based on Lithium chemistry. However, there is scope for research is still open. This includes the selection of the materials for cell manufacturing. The development of algorithms and designing of the electronic circuits for a better and effective utilization of the battery is also one of the area of research. For optimal performance of the batteries, it is important to keep check on the vital operational parameters of the battery during the charging and discharging. A battery management system (BMS) is one such mechanism for monitoring of the battery internal and ambient temperature, current, voltage and controlling the charging and discharging operation. In this paper, some of the interesting approaches and system for battery management is discussed. The requirement for the state of art system for optimal battery performance and its general architecture is also discussed.
