The ex-isting energy storage systems use various technologies, including hydro-electricity, batteries, supercapacitors, thermal storage, energy storage flywheels,[2] and others.
Since the electric motor functions as the propulsion motor or generator, it is possible to achieve greater flexibility and performance of the system. It needs more advanced energy management strategies to enhance the energy efficiency of the system.
Classification of ESS: As shown in Figure 5, 45 ESS is categorized as a mechanical, electrical, electrochemical and hybrid storage system. Classification of different energy storage systems. The generation of world electricity is mainly depending on mechanical storage systems (MSSs).
Classification of different energy storage systems. The generation of world electricity is mainly depending on mechanical storage systems (MSSs). Three types of MSSs exist, namely, flywheel energy storage (FES), pumped hydro storage (PHS) and compressed air energy storage (CAES).
For the EVs propulsion energy storage system, the existing development of ESSs is acceptable. It also reduces oil demand and subsequently reduces CO 2 emissions. With the technological changes and improvements, ESSs are continually maturing.
These types of motors are suitable for HEVs, which involves various speed ranges and high starting torque from the Integrated Stator Generator. In contrast, the VPM motor is preferable to in-wheel direct drive EVs owing to its low-speed profile with high torque density.
Two approaches, Hazard and Operability Analysis (HAZOP) and System Theoretic Process Analysis (STPA), were used to evaluate hazards associated with automotive rechargeable energy storage systems (RESSs). The analyses began with the construction of an appropriate block diagram of RESS functions and the identification of potential malfunctions.
