The broad adoption of electric vehicles can have a substantial effect on urban air quality, national energy independence, and international trade balance. The main technological component for the creation of viable electric vehicles is an efficient battery. This paper presents an improved and easy-to-use battery dynamic model where the type of battery used in this work is the first Ni-MH battery popular in electric vehicles. The battery model that was presented in this paper is a model that is already available in the Matlab library, but it has been explained during charge and discharge process and its outputs are obtained in an easier way for the readers, as the battery was a simple Ni-MH battery, whose four main outputs were Battery voltage, state of charge SOC, motor speed and motor armature current signal.
