Description
Smart BMS with all the features
Greetings everyone,
I designed this 7S BMS (Battery Management System) for monitoring as well as Balance Charging the battery.
it includes all the feature like
- Over current protection
- short circuit protection
- Over Voltage Protection
- Under Voltage Protection
- Over Temperature protection
- individual cell Voltage monitoring
This can charge battery with a maximum of 10A and can be programmed for any type of cell i.e. Li-ion, Li-Po, Li-fe and Ni-cd.
You can monitor cell Voltage over WiFi.
You can program it however you want.
Note: This version of the schematic is wrong. The latest version is linked at Smart BMS V2

Smart BMS with all the features
It is a 7S BMS based around ESP8266.
using the WIFI of ESP8266 one can monitor as well as change setting of the BMS over WiFi.

Hey.. Thanks for the feedback.. as i can see i have mistakenly interchanged the resistor in voltage divider.. i have rectified that issue in the next iteration you can check that out and please let me know how i can improve this design.. Link for the next iteration : https://www.pcbway.com/project/shareproject/Smart_BMS_V2.html Thanks and Regards Parmesh
