The growing interest in Electrical Vehicles (EVs) opens new possibilities in the use of Li-ion batteries in order to provide ancillary grid services while they are plugged to recharging stations. Indeed, Vehicle-to-Grid (V2G), Vehicle-to-Building (V2B), Vehicle-to-Home (V2H) as well as Vehicle-to-Vehicle (V2V) services can be carried out depending on the particular installation and on the connection to the distribution grid of the considered recharging station. Even if these are interesting and challenging opportunities, the additional charging/discharging cycles necessary to provide these services could decrease the expected life of EV batteries. For this reason, it is of paramount importance to study and develop reliable models of the batteries, which take the aging phenomena affecting the reliability of the Li-ion cells into account to evaluate the best charging/discharging strategy and the economic revenues. To this aim, this paper focuses on a battery pack made up with Li-ion nickel–manganese–cobalt (NMC) cells and proposes a semiempirical Electrothermal Aging Model, which accounts for both calendar and cycle aging. This modeling phase is supported by several experimental data recorded for many charge and discharge cycles at different C-rates and for several temperatures. Thus, it is possible to analyze and compare scenarios considering V2G services or not. Results show that the considered battery is subjected to a life reduction of about 2 years, which is a consequence of the increased Ah charge throughput, which moves from 120,000 Ah over 10 years (scenario without V2G services) to almost 230,000 Ah over 8 years (scenario with V2G services).

“…The equivalent circuit consist of the voltage source, internal resistance and parallel resistance and capacitance branches. There are few methods able to recognize the number of branches needed to accurately map the experimental data and the model of the specific battery [1]. The application of the experimental data to the model (the parameters estimation) can be performed with the use of various methods, such as curve fitting using MATLAB R (The MathWorks Inc., Natick, MA, USA) functions [1].…”

“…The application of the experimental data to the model (the parameters estimation) can be performed with the use of various methods, such as curve fitting using MATLAB R (The MathWorks Inc., Natick, MA, USA) functions [1]. Estimation of the model parameters is performed using pulse charging or discharging experimental tests [1][2][3][4][5][6][7][8][9]. In [2], the impact of the temperature was additionally taken into consideration, although it is not in the scope of this paper.…”

Abstract:The aim of the paper is to present the battery equivalent circuit for electric vehicle application. Moreover, the model described below is dedicated to lithium-ion types of batteries. The purpose of this paper is to introduce an efficient and transparent method to develop a battery equivalent circuit model. Battery modeling requires, depending on the chosen method, either significant calculations or a highly developed mathematical model for optimization. The model is evaluated in comparison to the real data measurements, to present the performance of the method. Battery measurements based on charge/discharge tests at a fixed C-rate are presented to show the relation of the output voltage profiles with the battery state of charge. The pulse discharge test is presented to obtain the electric parameters of the battery equivalent circuit model, using a Thévenin circuit. According to the Reverse Trike Ecologic Electric Vehicle (VEECO RT) characteristics used as a case study in this work, new values for vehicle autonomy and battery pack volume based on lithium nickel manganese cobalt oxide cells are evaluated.

In general, electric vehicles have significantly different structures compared to vehicles running on internal combustion engines owing to their use of electric motors as the source of power and batteries as energy-storage devices. Electric vehicles also demonstrate different driving performance and dynamic characteristics, as they are capable of recovering some of the energy wasted in the form frictional heat at the brake through use of regenerative braking during deceleration. The proposed study discusses a mathematical model constructed by identifying characteristics of certain key components and the hybrid control unit (HCU) of an electric vehicle. Corresponding correlations among these components were analyzed. In addition, a dynamic model of the electric vehicle was designed using the model-based design approach in accordance with the standard V-Model development process ISO 26262-an international standard for automotive safety. All models discussed herein were developed using the MATLAB/SIMULINK package, and dynamic characteristics of the vehicle were analyzed through simulations.
