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
