Design of Active Battery Management System for Electric Vehicle Battery

Abstract

In the literature, according to the special properties of li-ion cell physics, li-ion based battery technology must be used with caution in electrical vehicles. A balancing battery pack is one that has been regularly maintained. When all of the cells in the battery system are charged to the same level of charge, the balancing process takes place. The voltage of the cell is frequently the basis for this level. Numerous periods of recharging, during which the state of charge of each battery starts to differ considerably, cause a li-ion based rechargeable battery to become unbalanced. Temperature, cell chemistry, and the use of a BMS are just a few of the many factors that might cause this unbal- ancing. In this topology, the battery management system (BMS) will be examined as a method for balancing. This study will concentrate on the BMS as a tool to balance the battery cells, it offers a way to increase battery efficiency and longevity. To develop a fresh strategy for an effective system, two concepts based on earlier designs will be used. This design circuit helps to examine battery with new stage of working for electrical vehicles. A major advantage of balancing a lithium-based battery system is that it allows the system to run more efficiently. The capacity of the batteries decreases when they are charged and drained. Unbalanced cell discharging and charging shortens the time it takes for the cell capacity to be depleted until the system becomes useless or until the time it takes for the system to fail is shortened. The end user may obtain the most energy and life out of the battery system as a whole by evenly charging and discharging each single cell, which also saves money and resources. While the technology for using batteries as an energy source is currently behind, their power capacity, size, and impact on the environment are all constantly improving. As a result, it is impossible to overestimate the relevance of contemporary battery technology.
