Battery Management Systems (BMS) are used to monitor and control battery banks used in many industries and widely plays a vital role in the application of Electric Vehicle Industries. Nowadays, with a dominance of Lithium Ion (Li-Ion) batteries in most energy storage applications, BMS have become the essential device in Electric Vehicle (EV) from both a functionality and safety perspective.
A BMS allows users to monitor individual cells within a battery pack over parameters such as battery charging and discharging rates, state of charge estimation, state of health estimation, cell voltage, temperature, current etc. As cells work together to release energy to the load, it is crucial to maintain stability throughout the whole pack or else cells may get damage. This is where a battery management system (BMS) comes into play for safe operational working of system.
Nvis 425B demonstrates a battery management system which is integrated with controller for actively monitors the critical parameters like voltage, charging and discharging current, temperature along with continuously monitors each cell voltage in a battery pack and performs cell balancing if voltage difference between cells exceeds the threshold value makes the system complete understanding.
