Battery Management System
Simscape™
Battery™ includes Simulink® blocks that perform typical battery management system (BMS) functions,
such as state estimation, battery protection, cell balancing, and current management.
Use these blocks to implement estimation algorithms for battery cell state of charge and
battery cell state of health, simulate battery cell balancing algorithms, size the
balancing resistors, get and apply battery charging and discharging limits based on the
internal states, simulate battery protection algorithms, and much more. These libraries
are fully compatible with the custom battery models that you can generate by using the
buildBattery function.

Explore Techniques to Estimate Battery State of Charge
Explores different techniques to estimate the state of charge (SOC) of a battery, including the Kalman filter algorithm and the Coulomb counting method. The Kalman filter is an estimation algorithm that infers the state of a linear dynamic system from incomplete and noisy measurements. This example illustrates the effectiveness of the Kalman filter in dynamically estimating the SOC of a battery, even when starting with inaccurate initial conditions and when the measurements are noisy. The SOC of a battery measures the current capacity of the battery in relation to its maximum capacity.
Peak Shaving with Battery Energy Storage System
Model a battery energy storage system (BESS) controller and a battery management system (BMS) with all the necessary functions for the peak shaving. The peak shaving and BESS operation follow the IEEE Std 1547-2018 and IEEE 2030.2.1-2019 standards.
Protect Battery During Charge and Discharge for Electric Vehicle
Efficiently charge and discharge a battery for an electric vehicle (EV) and handle battery faults. Portable electronics and EV widely use li-ion batteries as power source due to their high-energy density. But li-ion batteries also have safety issues due to extreme conditions such as over-discharge, over-charge, high temperature, and low temperature. These extreme conditions can damage the battery and effect its performance in the long term. In some cases they can cause loss of stability which leads to thermal runaway.
