A Review of Energy Management Schemes using EV Batteries

Abstract

The population is increasing per minute and their energy demands are growing at an alarming rate. This begs the question of how this changing demand can be sustainably satisfied. There have been many strategies that were developed over the years that help the consumers to bring down their energy bills and their usage of energy to a reasonable level, but so far there are only few strategies that focus on both the consumer side and producer side. This project involves a new strategy for energy management in which we use the charging and discharging cycles of electric vehicle batteries as storage. In conventional power production stations, the generation depends on the demand at that particular time. Hence, the generators cannot always run at maximum efficiency and this may lead to losses. We are trying to introduce a “new strategy” where each electric vehicle acts both as load and storage. The period of low and high demand can be calculated from the values that are gathered from the respective load dispatch centre. During the time of low demand, the EV will charge and store energy in its battery. When the electric vehicles are not in use, they are plugged into the EV charging facilities. During the times of high demand, the EV will discharge to the connected load leaving behind a fixed percentage of charge in the battery for emergency vehicle usage. The amount of charge that should be retained in the battery can be controlled with the help of an application which will be available in the vehicle owner’s mobile phone. This will also help in promoting the interests of the increasing population. This strategy will also help the grid to have a storage system that is cost effective.
