Evolving Battery Management Systems for EV

In the new age of technology, we face different problems such as an increase in global warming and pollution, depletion of conventional energy resources, and carbon footprint. This leads to the use of electric vehicles. Choosing an energy storage system for these new technologies is an important task. So battery technology can be a good solution to the question. Hence, the Battery technology plays an important role in energy storage in these areas. It satisfies the purpose of being portable with a small size and can be placed anywhere. The performance of the battery depends on various factors like chemistry, temperature variation tolerance, load profile, and charging-discharging algorithm. For monitoring and controlling the Battery performance, a battery management system is established. BMS requires estimation of different parameters for the choice, monitoring, and controlling of the battery for better performance and efficiency when used for an Electric Vehicle. The paper covers topics related to battery parameter importance, estimations, and battery management systems for efficient operation. Common observations are like battery SOC estimation, SOH estimation, and SOT estimation for an efficient BMS.
