Ragone plot-based method for sizing an Electric Vehicle''s Battery

Recent studies have shown that the use of battery-battery coupling in Hybrid Energy Storage Systems (HESS) presents advantages in terms of mass, volume and cost when compared to the battery-supercapacitor coupling. However, the sizing of this type of system is not much studied in the literature. So, in this paper a graphical sizing method using Ragone plots is presented.

Non-isothermal Ragone plots of Li-ion cells from datasheet

The Ragone plot is one of the most conventional tools and presents the energy density versus the power density of different energy storage systems (ESSs) [4] [5] [6]. Regarding batteries [7] and electrochemical capacitors [8], the available discharged energy in the Ragone plot is usually obtained under a constant power discharge. However,

Theory of Ragone plots

Since the efficiency of an ESD is usually dependent on the working point, a single device belongs to a whole curve in the energy–power plane (see inset of Fig. 1).These so-called Ragone plots, which are usually presented in a log–log plot, are standard in the battery community since a long time [1] rst, they provide the limit in the available power of a battery

Failure limit analysis for Li-ion batteries using Ragone plot: a

Abstract: In this paper, a new possible definition of failure zone for Li-ion batteries is proposed. Based on the general concept that a battery can be considered failed when its performance no longer meets the requirements of the application for which it is designed, a new application-dependent failure zone definition is proposed using the Ragone plot of the cell.

Ragone plot

Ragone plot showing specific energy versus specific power for various energy-storing devices. A Ragone plot (/ r ə ˈ ɡ oʊ n iː / rə-GOH-nee) [1] is a plot used for comparing the energy density of various energy-storing devices. On such a chart the values of specific energy (in W·h/kg) are plotted versus specific power (in W/kg). Both axes are logarithmic, which allows comparing
