Disadvantages of electric vehicle energy storage

How EV technology is affecting energy storage systems?

The electric vehicle (EV) technology addresses the issue of the reduction of carbon and greenhouse gas emissions. The concept of EVs focuses on the utilization of alternative energy resources. However, EV systems currently face challenges in energy storage systems (ESSs) with regard to their safety, size, cost, and overall management issues.

What is the energy storage system in an electric vehicle?

The energy storage system is the most important component of the electric vehicle and has been so since its early pioneering days. This system can have various designs depending on the selected technology (battery packs, ultracapacitors, etc.).

What are the different types of eV energy storage systems?

The energy system of an EV can be subdivided into two main categories as an energy storage system and an energy consumption system. There are many technologies suitable for electric vehicle energy storage systems but the rechargeable battery remains at the forefront of such options.

What are the disadvantages of electric vehicles?

However, it has disadvantages such as having a heavyweight and a negative environmental footprint as well as short lifecycle and low specific energy (20–40 Wh/kg) and low power density which would mandate a huge mass to provide requirements for EV applications [61, , , , ].

Are rechargeable batteries suitable for electric vehicle energy storage systems?

There are many technologies suitable for electric vehicle energy storage systems but the rechargeable battery remains at the forefront of such options. The current long-range battery-electric vehicle mostly utilizes lithium-ion batteries in its energy storage system until other efficient battery options prove their practicality to be used in EVs.

Why do electric vehicles need energy management?

An electric vehicle relies solely on stored electric energy to propel the vehicle and maintain comfortable driving conditions. This dependence signifies the need for good energy management predicated on optimization of the design and operation of the vehicle's energy system, namely energy storage and consumption systems.
