This article provides a literature review on different types of battery models. These battery models having various characteristics are discussed and also described. Important battery parameters such as state of health (SOH), state of charge (SOC), operating time etc. are explained in this document. that affect battery performance. This document provides brief information on battery models. Furthermore, the merits and demerits of these battery models are summarized. The battery is used to store energy, basically to convert chemical energy into electrical energy or vice versa. This property of the battery is very useful in the power system. It is used everywhere for energy availability. Some of its main applications have been developed in the last decade of the year, these are:• The battery is in electric vehicles[1].• For energy storage in plants we use battery energy storage plants. In this we compensate for the active or reactive power flow.• Batteries are used in uninterrupted power supplies.There are many parameters related to battery modeling such as internal resistance, discharge type and discharge mode.Internal resistance consists of Self-discharge resistance, Resistors of charge and resistance to discharge, overload and excessive discharge[2]. In the type of discharge one is the continuous discharge in which the battery supplies the energy to the load without any pause and the other is the intermittent discharge which supplies the energy to the load for a period due to which recovery of the voltage occurs due an increase in tension. The discharge mode consists of constant load, constant current, constant power and charge/discharge rate. The high charging/discharging speed reduces battery life, to avoid this problem a battery management system will be introduced[3]. A control method is used to avoid...... half of the paper ......its part is the VI characteristics where and provides the transient response, and [24]. This modified model is used to predict the battery operating time and IV characteristics, but this model is not suitable for the transient response occurred due to a short duration load. This model is used in lithium-ion, NiMH, and lead-acid batteries to predict SOC, terminal voltage, and power losses. Accurate determination of the battery in this model, the discharge capacity is a function of the discharge rate i(t), temperature and number of cycles and also includes the rate factor. SOC and is given by the equation: This article is a literature review of different types of battery models. These models have different properties and different characteristics. State of charge, autonomy etc. we have different models for different applications like HEV/EV we use adaptive model
