The paper discusses the concept of energy storage, the different technologies for the storage of energy with more emphasis on the storage of secondary forms of energy (electricity and heat) as well as a detailed analysis of various energy storage projects all over the world.
The coupled photovoltaic-energy storage-charging station (PV-ES-CS) is an important approach of promoting the transition from fossil energy consumption to low-carbon energy use. However, the integrated charging station is underdeveloped. One of the key reasons for this is that there lacks the evaluation of its economic and environmental benefits.
The development of an optimal energy pile system involves complex analyzes. It comprises the selection of objective functions, the detection of decision variables and system design constraints, then the best optimization method.
Another challenge is that of the system economics. The economics of energy storage are difficult to evaluate since they are influenced by a wide range of factors: the type of storage technology, the requirement of each application, size and the system in which the storage facility is located .

When the number of EVs increases by 300 %, the optimal number of charging piles for the PV-ES-CS near hospitals increases significantly from 5 to 40. However, the optimal number of charging piles for the PV-ES-CS near office buildings does not increase from 5.
Energy storage is used to optimize the energy usage of the charging pile, and its adjustment span is defined as 10%-90%. Because the electricity price is different in various time intervals, the minimum limit of energy usage of the charging pile mandates that the electricity consumption of the grid in the flat period and peak period of ...
