Battery Management System
Charge | 2019
A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack), by protecting the battery from operating outside its safe operating area, monitoring its state, calculating secondary data, reporting that data, controlling its environment, authenticating it and / or balancing it, monitoring cell voltages, current and temperature and perform cell balancing to protect the cells.
In this project, there will be 4 lithium ion batteries whose voltage and temperature will be monitored on a webpage. An AtTiny will provide all the data using an ESP8266. If any of the battery overcharges, the BMS will balance out the battery voltage and then the final voltage of the battery will be displayed on the webpage.
