In this paper the current status of BEVs, HEVs, PHEVs, the use of FCs in the vehicles, and Fuel Cell Hybrid Electric Vehicle (FCHEV) including the comparison of the configuration, environmental impacts, and costs of these vehicles have been investigated.
ERSs have already been incorporated into ICE vehicles by BMW and Renault [12, 13]. However, Hybrid Electric Vehicles (HEVs) such as the Toyota Prius and BEVs such as the Nissan Leaf already incorporate kinetic energy recovery systems (KERSs) in their vehicles, which is also referred to as regenerative braking .
What are the different types of energy storage solutions in electric vehicles?
Battery, Fuel Cell, and Super Capacitor are energy storage solutions implemented in electric vehicles, which possess different advantages and disadvantages.
Can hydrogen fuel cells be used as energy storage solution for EVs?
The implementation of hydrogen Fuel Cells (FCs) as energy storage solution for EVs is another approach to reduce charging times and increase the range of the vehicle [ 14 ]. Furthermore, hydrogen can be produced from sterilized water through renewable energy sources and consequently, can be seen as a clean fuel.
Another alternative energy storage for vehicles are hydrogen FCs, although, hydrogen has a lower energy density compared to batteries.
What is energy storage in EVs?
In EVs, the type of energy storage is, together with the drive itself, one of the crucial components of the system.
Response times ranging from milliseconds to seconds and discharge durations spanning from seconds to hours are crucial for transportation applications. These requirements can be met by utilising a variety of energy storage technologies, including fuel cells, capacitors, supercapacitors, flywheels, and Li-ion batteries.
