Various ESS topologies including hybrid combination technologies such as hybrid electric vehicle (HEV), plug-in HEV (PHEV) and many more have been discussed. These technologies are based on different combinations of energy storage systems such as batteries, ultracapacitors and fuel cells.

The energy storage control system of an electric vehicle has to be able to handle high peak power during acceleration and deceleration if it is to effectively manage power and energy flow. There are typically two main approaches used for regulating power and energy management (PEM) [ 104 ].

Energy storage can be an effective solution, but a single storage unit may not suffice due to capacity, power, energy density, and life cycle limitations. Consequently, most researchers focus on hybrid energy storage systems that merge the most desirable attributes of multiple energy storage technologies to achieve pertinent

The electric energy stored in the battery systems and other storage systems is used to operate the electrical motor and accessories, as well as basic systems of the vehicle to function [20].

Nowadays, electricity is one of the most widely used forms of energy for sustaining nearly all human activities and is responsible for a large portion of greenhouse gas emissions [1].Although the effort to increase the share of renewable energy sources (RES) in energy markets, fossil fuels still provided 62 % of the world''s electricity

Fig. 2 shows a comparison of power rating and the discharge duration of EES technologies. The characterized timescales from one second to one year are highlighted. Fig. 2 indicates that except flywheels, all other mechanical EES technologies are suitable to operate at high power ratings and discharge for durations of over one hour.

Flywheel energy storage (FES) technology can deliver energy output either in kinetic form (rotational energy) or in electrical form. According to Chris Brockbank (business manager from Torotrak), FES energy conversion efficiency from braking energy to FES can reach up to 70% which is twice the efficiency of transforming energy from

The HPPC test is typically used to measure the dynamic electrical behavior of energy storage systems from the standpoint of either module or single cell. The test is characterized by several high discharging/charging current pulses at different SoC steps, from 100 % to 15 % [ 54 ].

Obviously, after the first 3 s, two cells (cell No. 2 and cell No. 3) are diagnosed as ESC fault because the RMSE in this time period is lower than the threshold ε 1; and after 5 s, the other four cells are diagnosed as ESC fault as well because the RMSE in

Single RC-ECM, along with hysteresis, is highly used for batteries having a high hysteresis effect in terminal voltage, and two RC-ECM is preferred in the energy storage system. Though increasing the RC network increases the modeling accuracy, it leads to a computational burden.
