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 Charging curve for cells at charge rate
  • 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

This will be built using go, and will utilise fyne for UI
