Design of Battery Management System

Abstract

The paper reviews the necessity and design of battery management circuitry and describes tests required for characterisation of Li-ion cell. The suggested design implements a novel cell balancing circuit comprising of only two active components. An individual cell monitoring board is economical when compared to open source solutions provided by Texas Instruments and Analog Devices, along with offering improved stack-ability. Design and analysis of cell balancing circuitry and electronic load, which can also be used as a battery-charger is discussed. The effect of the discharging rate on the capacity of a cell is analysed. The proposed design would aid to sustainable development and clean energy systems.
