Description
In this article we will learn **how we can measure the individual cell voltage of the cells used in a Lithium battery pack** and will design a simple circuit using op-amps to measure the individual cell voltages and **display it on a LCD screen using Arduino**. The mileage and performance of an [Electric Vehicles](https://circuitdigest.com/article/an-engineers-introduction-to-electric-vehicles) depends on the capacity and efficiency of its Battery Pack. To maintain the battery pack in full health is the responsibility of the Battery Management System (BMS). A BMS is a sophisticated unit in an EV which does a lot of activity like monitoring the cells, balancing them and even protecting them from temperature changes. Check out the complete project explanation here: [Project](https://circuitdigest.com/microcontroller-projects/multi-cell-voltage-monitoring-for-lithium-battery-pack-in-electric-vehicles)
