In this paper, functions of BMS in elections vehicles are explained. The BMS consists of number of electronics components for monitoring and controlling the functions of batteries in electrical vehicles (EVs). Nowadays, the EV has more concentrations because it has number of merits like compact in size, does not require fossil fuel so it is environment friendly, and cost-saving. The main components in EV are batteries because batteries decide the performance and efficiency of EV. So, we should give more importance to batteries.

INTRODUCTION: Electric vehicles (EV) are playing a key role because of its zero-emission of harmful gases and use of efficient energy. Electric vehicles are equipped by a large number of battery cells which require a effective battery management system (BMS) while they are providing necessary power. The battery installed in a electric vehicle should not only provide long lasting energy but also provide high power. Lead-acid, Lithium-ion,-metal hydride are the most commonly used traction batteries, of all these traction batteries lithium-ion is most commonly used because of its advantages and its performance. The battery capacity range for a electric vehicle is about 30 to 100 KWH or more. Battery management system (BMS) makes decisions based on the battery charging and discharging rates, state of charge estimation, state of health estimation, cell voltage, temperature, current etc.
Review of Battery Management Systems (BMS
The most crucial component of any electric vehicle (EV) is its battery storage, which stores the energy needed for the vehicle to function. So, an effective battery management system is required in order to get the most out of a battery while also ensuring its safe operation. BMS is a crucial component of any electric car, so there is still a lot of research going on to improve battery management systems. Monitoring, regulating, and optimizing the performance of the battery modules in an electric vehicle is very important. Another is the ability to regulate how the components are disconnected from the system in case of irregular conditions. This management system is nothing but the "battery management system (BMS)". BMS keeps track of the parameters, calculates SOC, and offers essential services to assure the battery's safe functioning. The functionality of BMS, topologies of BMS, and future technologies like wireless BMS are all thoroughly reviewed in this paper.
Analysis of Battery Management Systems
IRJET, 2022
The battery management systems also referred to as BMS is a battery management unit that is not only responsible to measure the state of battery accurately, but it also ensures safe operation and also a prolonged battery life. Because of their high energy density, lifespan, nominal voltage, power density, and low cost, lithium-ion (Li-ion) batteries have received a lot of attention in the EV industry. A smart battery management system (BMS) is an essential component in electric vehicles it not only measures the states of the battery accurately, but it also ensures safe operation and extends battery life. Estimating the state of charge (SOC) of a Liion battery accurately is difficult due to the battery's highly time variant, non-linear, and complex electrochemical system. So in this paper we will study about the various parameters related to battery performance like the state of charge, state of health and also look at over charge and under charge circuits that were designed to monitor the battery health.
CAN Communication Based Modular Type Battery Management System for Electric Vehicles
Elektronika ir Elektrotechnika, 2018
Lithium ion batteries are widely used in portable electronic devices and electric vehicles. Although battery technology has been significantly improved, it does not fully meet the energy requirements of electric vehicles. Electric vehicle batteries are built by serial and parallel connections of many cells to provide sufficient power. Differences between cells during battery usage can shorten the battery life and even worse can cause fire and explosion. Therefore, there is a need for a battery management system to ensure that the voltage, temperature and current information of the battery cells are used as optimum conditions. Cell balancing should be used to ensure that the battery cells are charging simultaneously. Cell voltage and temperature are measured by connecting auxiliary slave board to each series battery pack. This information is controlled by a master board. In this application, the excess energy is converted to heat by the load resistor on the utility boards. Fuzzy logic control is used to control the load resistor with the switching element. The charge status of the battery was estimated using the main battery current and the mains voltage with the master board. This application has been tested on an electric vehicle. A low cost modular battery management system has been developed that can control the safe charging and discharging of the vehicle battery.
A Review on Electric Vehicle Charging Systems
IRJET, 2022
Electric vehicles powered by batteries are becoming increasingly popular around the world. Several causes are driving this trend, including the need to reduce air and noise pollution and reliance on fossil fuels. To have a better understanding of how batteries behave in various situations. It is vital to be aware of certain battery performance factors in certain circumstances. A battery management system includes a battery fuel gauge, an optimal charging algorithm, and circuitry for cell and thermal balance. It estimates essential states and parameters of the battery system, such as battery impedance, battery capacity, state of charge, state of health, power decline, and remaining useful life, using three non-invasive measures from the battery: voltage, current, and temperature. This paper reviews several papers published regarding EV charging types, methods, BMS, state of charge.

This review paper discusses and compares various techniques presently used in improving the performance of Electric Vehicles (EVs) through different Battery Management Systems (BMS). Further, this paper discusses an improvised BMS based on the electrochemical properties of the battery. EVs use Permanent Magnet Synchronous motors, which are driven by the rechargeable batteries. Lithium-ion batteries are used in EVs. The present technologies can cover a distance of around 320 kilometers in a single charge of the battery module. The two important properties of an electrochemical battery are the Recovery effect and Rate Capacity effects have a decisive effect on the performance of the battery. These two effects and the surrounding temperature of the battery have been considered in the proposed new BMS. This would further increase the distance covered by the EV for a single charge which will result in the number of charging and discharging cycles, thus extending the overall life of the secondary batteries.
Battery-Management System (BMS) and SOC Development for Electrical Vehicles
—Battery monitoring is vital for most electric vehicles (EVs), because the safety, operation, and even the life of the passenger depends on the battery system. This attribute is exactly the major function of the battery-management system (BMS)—to check and control the status of battery within their specified safe operating conditions. In this paper, a typical BMS block diagram has been proposed using various functional blocks. The state of charge (SOC) estimation has been implemented using Coulomb counting and open-circuit voltage methods, thereby eliminating the limitation of the stand-alone Coulomb counting method. By modeling the battery with SOC as one of the state variables, SOC can be estimated, which is further corrected by the Kalman filtering method. The battery parameters from experimental results are integrated in the model, and simulation results are validated by experiment.
