Its main purpose is to start the car. With recent advancements, you can purchase a lithium-ion battery to jump start your car, and it only weighs a couple pounds and is the size of your hand. The ongoing transformation of battery technology has prompted many newcomers to learn about designing battery management systems.
A Battery Management Unit (BMU) is a critical component of a BMS circuit responsible for monitoring and managing individual cell voltages and states of charge within a Li-ion battery pack. The BMU collects real-time data on each cell’s voltage and state of charge, providing essential information for overall battery health and performance.
It is also the responsibility of the BMS to provide an accurate state-of-charge (SOC) and state-of-health (SOH) estimate to ensure an informative and safe user experience over the lifetime of the battery. Designing a proper BMS is critical not only from a safety point of view, but also for customer satisfaction.
There are many types of battery management ICs available. The grouping of the functional blocks varies widely from a simple analog front end that offers balancing and monitoring and requires a microcontroller (MCU), to a standalone, highly integrated solution that runs autonomously.
Figure 1. A Simplified Diagram of the Building Blocks of a Battery Management System A battery management system can be comprised of many functional blocks including: cutoff FETs, a fuel gauge monitor, cell voltage monitor, cell voltage balance, real time clock (RTC), temperature monitors and a state machine.
The BMU collects real-time data on each cell’s voltage and state of charge, providing essential information for overall battery health and performance. It constantly monitors and assesses the voltage levels of each cell to ensure uniform charging and discharging, preventing imbalances that could impact battery life.
A Guide to Designing A BMS Circuit Diagram for Li-ion Batteries
An ideal lithium-ion battery charger should have voltage and current stabilization as well as a balancing system for battery banks. The voltage of a fully charged lithium-ion cell is 4.2 Volts. Once the bank reaches this voltage, charging should stop. In this article, we will examine a circuit that allows charging Li-ion cells connected in series while also balancing …
