# OpenBPS

A free and open source hardware project to build a USB battery profiler and simulator. 

The software interface will allow for controlling the OpenBPS through it's various modes.

## Features

- Battery Profiling
    + Build discharge profiles for user selectable current draw
    + Save profiles in open format and plain text for easy analysis
    + Characterise a cell or batteries internal series resistance

- Compatible Cells/Batteries
    + Coin cells
    + A/AAA
    + Lithium
    + Li-Ion / Li-Poly (upto two in series)

- Cell / Battery Simulation
    + Low noise power supply
    + Output voltage follows profiled battery curve (whether profiled with device or supplied via CSV)
    + Simulation can be set to start and finish at different states of charge

This project will be updated as I work on software features and hardware design
