3S 4 amp 12V 18650 Lithium Battery Charger Board Protection Module
A Battery Management System (BMS) is an electronic system that manages and monitors the performance of rechargeable batteries, such as those used in electric vehicles, grid energy storage systems, and renewable energy systems. The primary functions of a BMS include:
Monitoring the state of charge (SOC) and state of health (SOH) of the battery: A BMS tracks the amount of energy remaining in the battery and determines its overall health, based on factors such as the number of charging cycles and the battery's temperature .
Balancing the cells within the battery: A BMS ensures that the cells within the battery are charged and discharged evenly, preventing any cell from being overcharged or over discharged, which can cause damage and shorten the battery's lifespan.
Controlling the charging and discharging of the battery: A BMS regulates the amount of current flowing into and out of the battery, ensuring that it operates within safe limits and preventing it from overheating or overloading.
Providing protection against overvoltage, under voltage, and overcurrent: A BMS has built-in safety mechanisms that prevent the battery from being damaged due to excessive voltage or current.
Providing communication and control interfaces: Many BMSs come equipped with communication protocols that allow them to interface with other systems, such as a vehicle's powertrain or a home energy management system.
Overall, a BMS is essential for ensuring the safe and efficient operation of a rechargeable battery, and it plays a critical role in maximizing the battery's lifespan and performance.
Welcome to my latest YouTube video! In this demonstration, I will be showingcasing a compact 3S battery management system that's compatible with 18650 lithium-ion cells. I will take you through the process of how to charge the cells using the BMS and test its performance by subjecting it to a 2 ampere load.
When designing a battery-powered project, it's important to create a battery system that can reliably power your project while in the field. This is where a battery management system (BMS) comes in handy. In this video, I will be using a BMS designed for use with 3 lithium-ion cells in series. The BMS comes with three input connections (B minus, B1, B2, and B plus) and a simple 2-pin connection for the load and charger.
I will demonstrate how to connect the cells to the BMS using cell holders for easy testing. I will also show you how to charge the lithium-ion cells using a DC-to-DC buck boost converter module to provide a constant voltage and current.
It's important to note that this BMS does not have a cell balancing feature. Therefore, I will show you how to verify the individual cell voltages to ensure they are all being charged evenly. I will also demonstrate how this limitation can lead to issues such as undercharging, overcharging, and quick depletion of weak cells due to the load, resulting in the BMS shutting off.
To test the BMS's performance, I will apply a constant 2 ampere load to the cells and monitor their voltage levels. You will see how the BMS will shut off the load when the third cell's voltage reaches the over-discharge voltage point.
