The charging power of a single charging pile is 350 kW. The installation and purchase cost of a single charging pile is $34,948.2. The service life of PV, ESS, charging pile, transformer, and other equipment is 15 years. The land cost of charging piles for 15 years is 524.2 $/m 2. The charging pile of a single electric bus covers an area of 40 m 2.
The number of charging piles is decided based on the number of electric bus charging at the same time. ESS capacity and maximum exchange power are decided according to the maximum amount of ESS energy and exchange power in a day. These three parts compose the planning scheme of the electric bus system.
The service life of PV, ESS, charging pile, transformer, and other equipment is 15 years. The land cost of charging piles for 15 years is 524.2 $/m 2. The charging pile of a single electric bus covers an area of 40 m 2. As the output of PV is related to conditions such as illumination, the output of PV will be different in a year.
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.
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.
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.
