Electric vehicles are the demand of the current scenario to fight with the increasing levels of pollution. Electric
vehicles operate by getting power from the battery which needs to be charged after a particular duration. Battery swapping
stations are used for providing the optimal power for charging these batteries. An algorithm known as Particle swarm
optimization can be used to find the optimal cost of these battery swapping stations. The project presents an expository study
about ParticleSwarm Optimization and thus various factors related to it.
