Automated Battery Management System for E Vehicles

Abstract

The Electric Vehicles (EV) Battery Management System (BMS) is a crucial part of EVs because it does important tasks like controlling charging and discharging, state detection, fault diagnosis and warning, data recording and analysis, etc. Nonetheless, new battery types are continually developing due to the quick advances in electrochemistry and materials related to batteries. An essential component for any system is the battery, which requires perfect maintenance to ensure optimal performance. It is now crucial to maintain the health of batteries in today's technologically advanced culture. In a fuel-cell/battery hybrid system, fuel cells, lithium-ion batteries, and related dc/dc converters are all included. Utilising energy management systems allows power sources (such as fuel cells and lithium-ion batteries) to be allocated according to demand. The state-machine approach is suggested due to the EV's limited compute capability and its simplicity in engineering implementation. Battery lifespan as well as efficiency can be significantly increased with the use of EB Power, AC/DC, and DC/DC converters for battery management. Furthermore, precise battery condition tracking and management are made possible by the combination of parts like PT/CT sensors, ADC converters, and PIC controllers. The use of an LCD screen and LM35 sensor improves accessibility for users, and the integration of IoT technology enables remote control and data collection and processing. Battery control is now an effective instrument for extending battery life and enhancing overall device performance due to its cutting-edge capabilities.
