As humanity is evolving the consumption of energy is increased. Continue power supply is not possible everywhere. So that we require energy storage devices. The stored energy is used in the places where the supply of energy is not available. The stored energy need to be a monitor protected and easy to use. With rapidly evolving technology of the smart grid and electric vehicles (EVs), the battery has emerged as the most prominent energy storage device, attracting a significant amount of attention.
The battery is a fundamental component of electric vehicles, standalone & other portable devices, which represents a step forward towards sustainable mobility. As an electrochemical product, a battery acts differently under different operational and environmental conditions....
The uncertainty of a battery’s performance poses a challenge to the implementation of these functions. It is a critical component of many electronics and electrical devices. Due to their high efficiency and high energy density, lithium-ion batteries have been adopted for mobile electronic devices and electric vehicles. Battery have been increasingly used further for various applications, such as small mobility vehicles (electric motorcycles, golf carts, etc.), stationary batteries for HEMS ( High Energy Management System ), trucks/buses and industry machinery. The very recent problem of pandemic have laid a increased risk of power failure and power demand, which on the edge resulted to a shortage of power supply and resources, this problem has emerged a bigger threat to many researches, manufacturing & production units, education and many other essential services, to satisfy their needs. Therefore this project on battery technology is helpful in satisfying their needs, which is growing very quickly, developing cells structure with higher power and energy densities, it is equally important to improve the performance of the battery management system (BMS) to make the battery a safe, reliable, and cost-efficient solution, to supply energy needs under power failure and even during power supply with self-sustaining technology to cater any load variations and demands.
A battery management system (BMS) is an electronic regulator that monitors and controls the charging and discharging of rechargeable batteries. It is simply battery monitoring, keeping a check on the key operational parameters during charging and discharging such as voltages, currents and the battery internal and ambient temperature. The monitoring circuits would normally provide inputs to protection devices which would generate alarms or disconnect the battery from the load or charger should any of the parameters become out of limits. The specific characteristics and needs of the smart grid and EVs, such as deep charge/discharge protection and accurate state-of-charge (SOC) and state-of-health (SOH) estimation, intensify the need for a more efficient BMS. The BMS should contain accurate algorithms to measure and estimate the functional status of the battery and, at the same time, be equipped with state-of-the-art mechanisms to protect the battery from hazardous and inefficient operating conditions. This BMS include the best choice of the cell materials and the development of electronic circuits and algorithms for a more effective battery utilization
Our project on Battery management system is providing the function of monitoring the storage energy protection from overload and overheating and easy to use for charging and discharging purpose. The stored energy can be transferred from one place to another place easily in the form of battery, cells or any store energy storage device. This project initially reviews the most interesting modeling approaches for predicting the battery performance and discusses the demanding requirements and standards that apply to ICs and systems for battery management. Then, a general and flexible architecture for battery management implementation and the main techniques for state-of-charge estimation and charge balancing are analysed, simulated and reported. Finally, we describe the design and implementation of an innovative BMS, which incorporates an almost fully-integrated active charge equalizer.
