EKF-SoC (C++)

C++ implementation of an Extended Kalman Filter for battery State‑of‑Charge estimation.

Requirements

• CMake ≥ 3.16
• C++17 compiler

Quick Start (Unix)

# from repo root
cmake -S . -B build -DCMAKE_BUILD_TYPE=Release -DCMAKE_EXPORT_COMPILE_COMMANDS=ON
cmake --build build -j
./build/ekf_soc_app

Test Data

• All data in signals.csv was generated from a MATLAB/Simulink project described here: https://www.mathworks.com/help/simscape-battery/ref/socestimatorkalmanfilter.html
• The data in signals_with_est.csv is the logged output estimate from running main.cpp
• Run validate_data.py to see a graph comparing the SOC estimate and the true SOC.

Estimate with initial SOC estimate 10% off from true SOC.

Tuning done in MATLAB and Simulink
