EV market players are aware that adopting Battery-as-a-Service (BaaS) is significantly going to reduce the capital costs of buying an electric vehicle to about 30-50%. <\/p>\n<p>Certainly, the battery swapping policy will facilitate the EV market to acquire a larger share as more and more electric scooters, cars, buses, and cargo trucks will be driven on the roads. As a result, power designers will face the challenge of delivering systems that can be adapted to a wide variety of batteries and vehicles with vastly diverse performance requirements. Just like the human brain, which controls the whole functioning of our body, a battery management system (BMS) is the brain behind the EV battery pack.<\/p>\n<p>A battery management system has electronic components and a combination of functions and features necessary to meet the battery pack\u2019s safety and operational requirements. BMS looks after the battery\u2019s SOC (State Of Charge) so that it remains in a predefined range and it scans the change in its SOH (State Of Health). This functioning strategy involves shielding from high currents and large temperature variations.<\/p>\n<p>Let us understand the key <b>components of battery management system<\/b>, different parts of battery management system, and battery management system architecture diagram.<\/p>\n<h2>The Importance of Battery Management System<\/h2>\n<p>Battery Management System is the chief in command for performing critical operations in a battery pack and provides the following functionality:<\/p>\n<ul class=\"bullets text-left\">\n<li>Voltage, Current, and Temperature control and measurement<\/li>\n<li>SOC and SOH assessment<\/li>\n<li>Detection of fault<\/li>\n<li>Passive cell balancing<\/li>\n<li>Data storage<\/li>\n<\/ul>\n<p class=\"boxed bg--secondary\" style=\"border: 1px solid #c7c7c7; box-shadow: 0 0 40px rgba(0, 0, 0, 0.2);\"><strong><em><span style=\"font-size:22px; color:#000;\">Check out our customized BMS product range as per your battery pack arrangement.<\/span><br \/>\nWith <a href=\"https:\/\/bacancysystems.com\/battery-management-system?utm_source=blog&#038;utm_medium=bacancy%27s_bms&#038;utm_campaign=components-of-battery-management-system\" target=\"_blank\" rel=\"noopener\">Bacancy\u2019s BMS<\/a>, you can maximize your Lithium-ion battery safety, performance, and longevity.<\/em><\/strong><\/p>\n<h2>Analyzing the Components of Battery Management System for EV<\/h2>\n<p><img decoding=\"async\" loading=\"lazy\" width=\"1100\" height=\"600\" src=\"https:\/\/bacancysystems.com\/blog\/wp-content\/uploads\/2022\/02\/Analyzing-the-Components-of-Battery-Management-System-for-EV-min.jpg\" alt=\"Analyzing the Components of Battery Management System for EV\" class=\"alignnone size-medium wp-image-23914\" srcset=\"https:\/\/bacancysystems.com\/blog\/wp-content\/uploads\/2022\/02\/Analyzing-the-Components-of-Battery-Management-System-for-EV-min.jpg 1100w, https:\/\/bacancysystems.com\/blog\/wp-content\/uploads\/2022\/02\/Analyzing-the-Components-of-Battery-Management-System-for-EV-min-300x164.jpg 300w, https:\/\/bacancysystems.com\/blog\/wp-content\/uploads\/2022\/02\/Analyzing-the-Components-of-Battery-Management-System-for-EV-min-1024x559.jpg 1024w, https:\/\/bacancysystems.com\/blog\/wp-content\/uploads\/2022\/02\/Analyzing-the-Components-of-Battery-Management-System-for-EV-min-768x419.jpg 768w\" sizes=\"(max-width: 1100px) 100vw, 1100px\" \/><\/p>\n<p><em><u>Fig:<\/u> Battery Management System architecture diagram<\/em><\/p>\n<p>Mainly, there are 6 <em>components of battery management system<\/em>. <\/p>\n<p>1. Battery cell monitor<br \/>\n2. Cutoff FETs<br \/>\n3. Monitoring of Temperature<br \/>\n4. Cell voltage balance<br \/>\n5. BMS Algorithms<br \/>\n6. Real-Time Clock (RTC)<\/p>\n<p>Let\u2019s look at the significance and the application of each components of battery management system:<\/p>\n<h3>1. Battery cell monitor<\/h3>\n<p>A battery cell monitor primarily monitors the voltages for battery systems. It is a high-speed system that offers a low overall cost for high voltage measurements.<\/p>\n<ul class=\"bullets text-left\">\n<li>The easiest way to determine the battery pack\u2019s charge is to monitor individual cell voltage with reference to the set voltage level.<\/li>\n<li>When the voltage of the first cell reaches the voltage limit, the charging automatically trips. It indicates that the battery charging limit has been reached.<\/li>\n<li>If the battery pack has a lesser charge than the average cell, then the least charged cell will reach the limit first, and the rest of the cells will be left partially charged.<\/li>\n<\/ul>\n<h3>2. Cutoff FETs<\/h3>\n<p>FET driver is accountable for connection and isolation between load and charger of the battery pack. The behavior prediction is done through voltage, current measurements, and real-time detection circuitry.<\/p>\n<ul class=\"bullets text-left\">\n<li>They can be connected to a battery pack&#8217;s low or high side.<\/li>\n<li>NMOS FETs activation is needed for enabling high-side connection and requires a charge pump driver. A reference for the solid ground is set using a high-side driver for the rest of the circuitry.<\/li>\n<li>We use a low-side FET driver to reduce costs in integrated solutions since a charge pump is not needed. High voltage devices are not required in such cases.<\/li>\n<li>The ground connection of the battery pack floats using low-side cut-off FETs. This can affect the IC performance, making it more sensitive to insinuated noise measurement.<\/li>\n<\/ul>\n<h3>3. Monitoring of Temperature<\/h3>\n<p>With the increase in product requirements, the batteries have been on a constant surge in delivering currents at fixed voltages. The continuous operation processes may cause a catastrophic event such as fire or explosion.<\/p>\n<ul class=\"bullets text-left\">\n<li>We can identify whether battery charging or discharging is desirable using temperature measurements.<\/li>\n<li>Temperature sensors monitor the energy storage system or cell grouping for compact portable applications.<\/li>\n<li>The circuit temperature is monitored by the internal ADC voltage-powered thermistor. Employing the internal voltage reference helps reduce the temperature inaccuracies and improves the overall measurement system.<\/li>\n<\/ul>\n<h3>4. Cell voltage balance<\/h3>\n<p>It is crucial to determine the health of the battery pack. That is why cell voltage monitoring is done to ensure that the cells are in a proper running condition for attaining a long battery life. <\/p>\n<ul class=\"bullets text-left\">\n<li>The operating voltage ranges from 2.5V to 4.2V in a lithium-ion battery.<\/li>\n<li>The battery life is significantly affected while performing battery operations beyond the voltage range. This reduces the life of a cell, which may even make it unfit for use.<\/li>\n<li>Connecting the battery pack in parallel increases the overall drive current, whereas series connection adds the overall voltage.<\/li>\n<\/ul>\n<h3>5. BMS Algorithms<\/h3>\n<p>To make quick and effective decisions in real-time based on the information received. For this purpose, a microcontroller for <a href=\"https:\/\/bacancysystems.com\/blog\/battery-management-system-for-electric-vehicle\" target=\"_blank\" rel=\"noopener\">battery management system<\/a> is needed to collect, organize and assess the information from the sensing circuitry. <\/p>\n<ul class=\"bullets text-left\">\n<li>Renesas\u2019 ISL94203 is the most famous example of employing a battery management system algorithm. It is a standalone digital solution embedded in a single chip with programmable capabilities.<\/li>\n<li>The memory space and microcontroller for battery management system clock cycles can be cleared using these standalone solutions.<\/li>\n<\/ul>\n<h3>6. Real-Time Clock<\/h3>\n<p>Allowing the user to know the battery pack\u2019s behavior before any alarming event, the real-time clock acts as a black box system for time-stamping and memory storage.<\/p>\n<ul class=\"bullets text-left\">\n<li>The BMS electronics is kept away from synchronizing with a third-party battery pack through battery authentication.<\/li>\n<li>The peripheral power circuitry is used around the components of battery management system through voltage reference\/regulator.<\/li>\n<\/ul>\n<h2>How does Battery Management System work?<\/h2>\n<p>The battery management system tracks the status of each cell in the battery pack. Determining the SOC (State of Charge) and SOH (<a href=\"https:\/\/bacancysystems.com\/blog\/state-of-charge-calculation-for-battery-energy\" target=\"_blank\" rel=\"noopener\">State of Health<\/a>) helps estimate the amount of current needed for a safe charge and discharge operation without harming the battery.<\/p>\n<p>The current limits act as a cut-off and prevent the battery from overcharging. This safeguards the cell voltages of the battery pack from high or low  fluctuations, which immunes the battery life.<\/p>\n<p>The BMS consistently tracks the charge and discharge activities for the battery pack and monitors cell voltages. This data is useful in deciding if the battery is drained, sustaining passive cell balancing.<\/p>\n<p>The CAN (Controller Area Network) bus is the reliable unit for internal communications, driving most of the messaging protocols. The IEM (Intelligent Electric Meter) estimates the state parameters of the battery pack, total current, and battery pack voltage. It transfers the information to the CMU (Central Monitoring Unit) or the sub-controller unit. <\/p>\n<p>The sub-controller unit quickly checks the temperature and voltage signals and sends data to the CAN bus. The BCU (Battery Control Unit) obtains the signals from the CAN bus and responds by transmitting back the control signals required in battery pack managing and modeling.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" width=\"1100\" height=\"696\" src=\"https:\/\/bacancysystems.com\/blog\/wp-content\/uploads\/2022\/02\/How-does-Battery-Management-System-work-min.png\" alt=\"How does Battery Management System work\" class=\"alignnone size-medium wp-image-23915\" srcset=\"https:\/\/bacancysystems.com\/blog\/wp-content\/uploads\/2022\/02\/How-does-Battery-Management-System-work-min.png 1100w, https:\/\/bacancysystems.com\/blog\/wp-content\/uploads\/2022\/02\/How-does-Battery-Management-System-work-min-300x190.png 300w, https:\/\/bacancysystems.com\/blog\/wp-content\/uploads\/2022\/02\/How-does-Battery-Management-System-work-min-1024x648.png 1024w, https:\/\/bacancysystems.com\/blog\/wp-content\/uploads\/2022\/02\/How-does-Battery-Management-System-work-min-768x486.png 768w\" sizes=\"(max-width: 1100px) 100vw, 1100px\" \/><\/p>\n<p><em><u>Fig:<\/u> Battery Management System layout<\/em><\/p>\n<p class=\"boxed bg--secondary\" style=\"border: 1px solid #c7c7c7; box-shadow: 0 0 40px rgba(0, 0, 0, 0.2);\"><strong><em><span style=\"font-size:22px; color:#000;\">Explore how Bacancy can help you build a high performing electric vehicle, e-rickshaw\/scooter battery with long-lasting battery life.<\/span><br \/>\nGet in touch with the <a href=\"https:\/\/bacancysystems.com\/?utm_source=blog&#038;utm_medium=leading_product_engineering_company&#038;utm_campaign=battery-management-system-for-electric-vehicle\" target=\"_blank\" rel=\"noopener\">Leading Product Engineering Company<\/a><\/em><\/strong><\/p>\n<h3>Types of Battery Management Systems:<\/h3>\n<p>Based on the topology of the battery packs, there are 4 types of battery management systems.
