As the number of electric vehicles (EVs) increases rapidly, the problem of electric vehicle charging has widely become a concern. Therefore, considering the fact that charging time for one EV cannot be shortened quickly and the number of charging stations will not expand rapidly, how to schedule charging operations of electric vehicles in urban areas becomes a

While PHEVs are less reliant on public charging infrastructure than BEVs, policy-making relating to the sufficient availability of charging points should incorporate (and encourage) public PHEV charging. If the total number of electric LDVs per charging point is considered, the global average in 2022 was about ten EVs per charger. Countries

2.1 Electric Vehicle Modeling. EVs are in driving, parking and charging states, so charging loads need to be calculated according to different states. When an EV is in the parking state, the charge is almost unchanged, so its potential charging load can be ignored; when it is in the driving state, as the charge decreases, the possibility of the owner wanting to

The new energy storage charging pile system for EV is mainly composed of two parts: a power regulation system and a charge and discharge control system. The power regulation system is the energy transmission link between the power grid, the energy storage battery pack, and the battery pack of the EV.
The charging pile determines whether the power supply interface is fully connected with the charging pile by detecting the voltage of the detection point.
