One of the requirements in electrical system is rechargeable battery and its precise management. The Battery management system BMS monitors very important battery parameters i.
Open circuit voltage and integral of discharging current of the battery be used for estimation of SOC and are the function of SOC. The on line measurement and comparison of the predicted and measured terminal voltage and integral of current provides a tool for estimating the SOC and SOH.
The BMS is also used for calculating secondary reports and reporting the generated data. The BMS also helps in controlling or balancing battery environment.
In this research paper attempt is made to design the battery management system for electrical system or plug-in vehicles. The rechargeable battery plays major role for deciding many electrical specifications of battery operated vehicle. The high level of energy and power density of batteries makes them suitable as the energy storage in electric, hybrid electric vehicle, and plug-in vehicles.
Multi-battery parameter reading or recording is an important way for studying the functions the rechargeable battery. Monitoring of the battery performance parameters gives more information about the battery status and health of the battery. Recently, many commercial data acquisition systems are available and are also powerful. The battery management system BMS is an electronic system that manages battery and battery parameters precisely.
The BMS system monitors important battery parameters like state of charge, state of health, coolant flow for air or fluid, ampere hour counting, terminal voltage and flowing current in and out. The BMS helps in controlling or balancing battery environment. As far as electrical vehicles concern the fuel gauge of the battery makes direct use for decision making for driving a car. Instead of displaying battery parameters like voltage, current and AH values, the mileage and SOC in terms of fuel gauge is displayed on the computer screen.
After complete development of the system it would be directly displayed on car dashboard. Owing to the improvement of computing power, computer-aided multi-unit acquisition and separation rapidly proliferated during the last two decades. To utilize this technology is, however, not easy since task-specific designs are usually mandatory.
To overcome this obstacle, a commercially available National Instrument NI USB , data acquisition system is used to evaluate, this research paper describes a design and development of a real time monitoring system for the measurement of battery performance parameters. The battery performance parameters are computed continuously with designed hardware and software setup. The designed system monitors battery related parameters and provides information regarding health of the rechargeable battery.
This experimental data could be used to know certain parameters of battery like rate of charging, rate of discharging and power drawn by electrical loads.
Real time monitoring system provides key information to the user in an electrical car or battery operated systems or electrical power system in deciding mileage, range, specifications and other related parameters.
The BMS system monitors very important battery parameters like state of charge, state of health, coolant flow for air or fluid, ampere hour counting, terminal voltage and flowing current in and out. The state of the battery and it may be as represented by various electrical parameters of the battery i.
In this work the terminal voltage, temperature, state of charge SOC or depth of discharge DOD are displayed on the screen of computer as shown in fig.
In this monitoring system range of vehicle in km and amount of state of charge in percentage is displayed and which is needed for driver of the electrical vehicle. PresentationLoad Follow. Insurance Lead Management.
