T3CO : Transportation Technology Total Cost of Ownership Tool

Description

This repo houses T3CO (Transportation Technology Total Cost of Ownership), software for modeling total cost of ownership for commercial vehicles with advanced powertrains.

To get started, read the Quick Start Guide

For information on the T3CO models, go to the Overview

Usage

T3CO is a general framework allowing a user to determine the total cost of ownership (TCO) of a FASTSim vehicle (paired with a FASTSim DriveCycle(s) for determining fuel efficiency). The user can also determine performance of gradability, acceleration, and range. In addition to straight TCO computation there is also the option to optimize a vehicle powertrain such that it meets performance optional targets while also optionally minimizing TCO.

Installation

Installing From PyPI

T3CO can be easily installed from PyPI. This is the preferred method when using T3CO as a dependency for a project. To install the latest release:

pip install t3co

To install a specific version (for example T3CO v1.0.8):

pip install t3co==1.0.8

From GitHub

T3CO can also be installed directly from the GitHub repository for accessing demo input files and running T3CO using the Command Line Interface.

First, clone the repository from GitHub:

git clone https://github.com/NREL/T3CO.git T3CO

From within the Python environment Navigate to the parent directory containing the T3CO repository e.g. cd github/T3CO/ and run:

pip install -e .

This installs the local version of the T3CO clone along with all its dependencies.

Demo

Using the T3CO Config file

Create a new analysis_id on ./t3co/resources/T3COConfig.csv or update the existing rows and use them to run T3CO.

cd t3co
python sweep.py --analysis-id=0

Using Command Line Arguments

cd t3co
python sweep.py --skip_all_opt --selections  [1,2,3,4,5] --dst_dir .t3co_results/demodata

using optimiztion in sweep module see
