Abstract
The battery is one of the fundamental parts of electric vehicles, mobile phones, laptops, and other electronic equipment. Among all types of rechargeable batteries, lithium-ion batteries are more beneficial because of their appropriate features than other batteries and govern the battery market. In this article, we introduce a Battery Management System for overcoming the electrical and temperature hazards of lithium-ion batteries. The proposed Battery Management System is solely general and manages 10.8V to 48V battery pack at all stages of charge, discharge, and electrical rest, individually. In this way, the battery is protected against over-current when charging and discharging, over-voltage, under-voltage, over-temperature, and under-temperature. The system also has short circuit protection and reverses the connection of the charger protection. The main application and approach of the proposed Battery Management System is electric vehicle battery (48V/50Ah) management. Also, the proposed Battery Management System can work in Master-Slave configuration for high-voltage battery pack management.
