A Review: Power Quality Problems Associated with EV Charging Station

Electrical Vehicles (EV's) are best option for conventional vehicles as it is free from CO2 emission.Electric vehicle charging stations are used to charge EVs.Nonetheless, there are significant differences in EV loads (while charging) depending on the battery technology used and the charging technique (slow, fast, ultra flash, or flash charging).EVs can be charged in less than a minute using flash charging mode, which uses more grid power.The distribution network is negatively impacted by widely disparate EV charging characteristics, including overloading, stability issues, power quality issues, bad voltage profiles with other users connected to the same distribution network, etc.
