Abstract: Battery Management Systems (BMS) is a vital piece of electric vehicles and the hybrid electric vehicles. precision of these systems has consistently been a state of conversation as they for the most part give a mistake of greatest 10% considering all the parameters together. The BMS plays out the assignments by incorporating at least one of the capacities, for example, examining the voltages of  battery cell and the temperatures in battery module, testing the voltages of the battery, inspecting the current of the battery, just as cells adjusting and finding state of charges .In this paper we are discussing about the cell voltages, battery temperatures, battery voltages, and battery currents. sampling of cell voltages, temperatures, cell balance can done with the use of the special type of the Integrated Circuit (IC). This special IC settle the issues of inspecting cell voltages in Li-ion battery, that have several cells. This paper also determines the parameter of the battery.
