Free QuoteThe 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.
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.
For instance, the APP of TELD, that is, a leading charging facility manufacturer and operator in China, claims that the DC charging pile's advertised charging power of 60–150 kW is 60 kW, but the highest charging power it is capable of is about 90–100 kW.
In the current situation of energy scarcity, the extensive deployment of electric vehicles (EVs) and their supporting infrastructure is one of the critical initiatives to accelerate the construction of a new generation of power systems and promote the realization of green, safe, efficient, and sustainable development of energy [1, 2].
The capacity optimization model of the integrated photovoltaic- energy storage-charging station was built. The case study bases on the data of 21 charging stations in Beijing. The construction of the integrated charging station shows the maximum economic and environment benefit in hospital and minimum in residential.
The power supply and distribution system, charging system, monitoring system, energy storage system, and photovoltaic power generation system are the five essential components of the PV and storage integrated fast charging stations. The battery for energy storage, DC charging piles, and PV comprise its three main components.
