Global challenges of electric vehicle charging systems and its However, such an increase caused by going from 30% to 80% EV penetration under the uncontrolled charging scenario may exceed 100% of the preliminary daily energy loss (267 kWh), while the increased energy losses remain below 40% for valley-filling and uniform charging, and below 55% for the conditional
In this paper, the battery energy storage technology is applied to the traditional EV (electric vehicle) charging piles to build a new EV charging pile with integrated charging, discharging, and storage; Multisim software is used to build an EV charging model in order to simulate the charge control guidance module.
The simulation results of this paper show that: (1) Enough output power can be provided to meet the design and use requirements of the energy-storage charging pile; (2) the control guidance circuit can meet the requirements of the charging pile; (3) during the switching process of charging pile connection state, the voltage state changes smoothly.
Currently, new energy vehicle charging piles are manual charging piles. Due to the fixed location of the charging piles and the limited length of the charging cables, manual charging piles can only provide charging services for the vehicles to be charged in the nearest two parking spaces at most.
With the development of technology, the number of new energy vehicles continues to increase, and community residents have an increasingly strong demand for charging and energy replenishment. Public charging piles have become the most lacking “new community infrastructure” in the community.
However, first of all, the vehicle-to-pile ratio needs to reach 1:1. If the number of charging piles is greatly increased, the power system will inevitably need to be expanded, which will be costly. The investment cost of charging stations is high and the equipment utilization rate is low, resulting in a waste of charging resources.
In Ref. , Mouli et al. designs a charging scenario of “few piles to many vehicles', where a single charging pile can provide charging services for vehicles to be charged in multiple charging parking spaces through multiplexed charging lines.
