How many charging piles are there?

The demand for slow charging piles is only 18. Its total number is 30. There is a reduction of 80% compared with the 153 charging piles obtained from the charging demand forecast. Assume that the time cost of electric vehicles to queue or transfer to a new charging station is the same as the time cost of fuel vehicles.

What is the optimal number of charging piles for PV-es-cs near hospitals?

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.

What data does a charging pile have?

The data of charging piles include the charging pile code, location, user’s code, start time, end time, charging capacity, etc. 2.2. Research Framework

Do private charging piles affect accumulated charging power?

Promoting the adoption of private charging piles will hardly affect the accumulated charging power but will transfer the charging load from public piles to private ones. Due to the different load profiles of the two charging piles, the charging peak will be weakened by day but enhanced at night.

What are the characteristics of charging piles?

Some conclusions can be drawn. (1) The charging load profiles of different types of charging piles show different temporal characteristics. That of private piles is widely distributed with a gentle slope and a long peak in the evening, while that of public piles has two peaks, during working hours and before midnight.

How to optimize the configuration of electric vehicle charging piles?

When optimizing the configuration of electric vehicle charging piles, it’s necessary to consider the limited number of charging piles in the parking lot. We assume that the charging information can be shared with EVs in real-time to provide decisions for charging decisions and path planning. 3.11.2. Route planning
