Distribution Switchboard for Slow Charger of EV able to Distribute Power as a Function of Available Power capacity: Presented at EVS 31 EVTeC 2018, Kobe, Japan, October 1 - 3, 2018

摘要

As the distribution of electric vehicles has been recently facilitated, charging infrastructures have been rapidly increased. Generally speaking, "standard chargers are 7.7kW in capacity, and the maximum capacity is reduced based on the number of chargers for the purpose of use. However, it costs a lot of money to install such infrastructures as power facilities in order to supply power according to the maximum capacity considering the distribution rate of electric vehicles. It might also result in overwhelming circumstances where supply and demand of electricity are concentrated in the summer. In an effort to resolve these problems, the paper is focused on suggesting the concept of smart distribution switchboards for standard charging where power can be distributed according to available power capacity as well as a method of interlinking them with the existing standard chargers before proposing a method of generating signals to stop charging in order to counter mechanical troubles caused due to the quality of electricity. We simulated the above using MATLAB, Simulink, and VeriStand.
