evsim

Overview

evsim is part of a suite of packages to analyse, model and simulate the charging behavior of electric vehicle users:

• evprof: Electric Vehicle PROFiling
• evsim: Electric Vehicle SIMulation

evsim package provides the functions for:

• Simulating new EV sessions based on Gaussian Mixture Models created with package {evprof}
• Calculating the power demand from a data set of EV sessions in a specific time resolution
• Calculating the occupancy (number of vehicles connected) in a specific time resolution

Usage

If you have your own data set of EV charging sessions or you have already built your EV model with evprof, the best place to start is the Get started chapter in the package website.

Installation

You can install the package from CRAN or the latest development version from GitHub:

# CRAN stable release
install.packages("evsim")

# install.packages("pak")
# pak::pak("resourcefully-dev/evsim")
install.packages("evsim", repos = c('https://resourcefully-dev.r-universe.dev', 'https://cloud.r-project.org'))

Getting help

If you encounter a clear bug, please open an issue with a minimal reproducible example on GitHub.
