What are the types of charging pile? 1. Different installation locations: public charging piles and charging piles built with the vehicle. 2.
To build a charging pile, the initial investment cost is low, the investment time is relatively small, and the occupied area is also small. Long charging time. Charging piles have always been regarded as the most standard energy supplement method for new energy vehicles. In slow charging mode, the charging process takes 6-8 hours.
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.

Charging pile is a device used to charge electric vehicles (EV). Its function is similar to that of a fuel dispenser in a gas station. It can charge various types of electric vehicles according to different voltage levels. It is a alternative of traditional gas station and gas pump.
Under the assumption of fast charging rules (the vehicle must leave when it''s fully charged), if the parking time is longer than the expected fast charging time, the EV chooses slow charging to avoid moving the car, and the demand for slow charging piles in the parking lot increases by 1; On the opposite, the EV chooses fast charging and the demand for fast …

Results show that during the planning period, the installation number of energy storage charging piles will significantly increase when V2G proportions expands. The total costs consistently show a descending trend if EVs participating more in V2G. When the V2G proportions increase from 25 % to 100 %, the total CO 2 emissions decrease by 4.49 %.
In summary, existing research primarily focuses on the scheduling of EV charging stations that include energy storage or renewable energy sources, with limited analysis on the profitability of charging stations that solely consist of charging piles. This limits the practical applicability of the research findings. Additionally, current studies ...
