Lithium batteries, with their chemical evolutions, are increasingly used in our life.

The main applications of powerful battery packs are electric mobility and domestic energy storage for photovoltaic panels.

These technologies are improving our lives by helping us to reduce the problem of pollution and will be used more and more in the future.

All lithium batteries need a BMS ... so the BMS is an essential component for an eco-sustainable future!

Green BMS was born for fun, but it can be an interesting project, because it is simple, modular and ... open!

Anyone can make it to manage their own DIY battery system.

Anyone can improve it, customize it and adapt it to their needs.

I believe that the great added value of Green BMS is to be Smart with the Android application: there are few open source projects of this type that include a fully open Android application.

And what about the weak points?

There are many improvements that can be made to the project, here are some examples:

Cell Module:

• Reduce the size: I’d like to modify power resistors in order to reduce each PCB size to adapt it to smaller cells
• Improve the balancing circuit in order to move mosfet protection out from controller logics
• Realize an optional module board that manages more cells at time (for small battery packs).
• Find solutions to make it cheaper

Control Unit:

• Base the Control Unit on a smaller, lower consumption microcontroller (ESP32)
• Increase the number of cells to manage
• Add new interfaces with most popular chargers, using canbus and pwm signals
• Add Low temperature protection
• Add IOT functionality (I'm already working on this …)

Smartphone application:

• Create it for IOS phones
• Add solar panel management

 ... and other important improvements that I have in mind, but which I do not want to anticipate for the moment …

I am proud of this project and happy to share it with the world!

Go green with Green BMS!
