A Review on Battery Management System

In the modern era, Electric Vehicles (EVs) are widely considered as a superior alternative to traditional automobiles that rely on internal combustion engines (ICEs). The rapid advancement of EV technologies has made battery systems a crucial aspect of their development. In recent times, the upgradation of battery technology along with the increase in demand for high-performance and safe battery system has driven various developments in the battery management system (BMS). The development of a BMS system is also required for the integration of smart technologies such as IoT and machine learning. A BMS is a control process used for managing and monitoring rechargeable batteries to ensure their effective and safe operation. It is responsible for monitoring variables like voltage level, temperature, and charge status and taking necessary actions to maintain them within limits. In this paper SOC, SOH, thermal management, and cell balancing techniques are discussed, which protect against excessive charging and discharging, and overcurrent conditions. This study presents a literature survey on a BMS, for dependable and secure operation of battery systems in the EV.
