Minimizing Carbon Emission during EV Charging

Carbon Aware EV Charging

Carbon-aware EV charging is a collaborative project between the Lawrence Berkeley National Laboratory and the Department of Electrical and Computer Engineering with the goal of discovering an EV charging strategy that minimizes carbon emission during EV charging sessions.

We use dataset from the California Independent System Operator as well as the EV charging session data from the Berkley lab to simulate the optimization problem.

Dataset

• Emission Data: http://www.caiso.com/todaysoutlook/pages/emissions.html
  • Zip File in this Repo: CAISO_CO2_per_resource_2021.zip
• Supply Data: https://www.caiso.com/todaysoutlook/Pages/supply.html

• EV Charging Dataset (Provided by Berkley Lab)
  • csv file in this repo: LBNL_Data.csv

Consolidate python script

These 2 scripts uses the csv library to iterate through all dates to summarize the year round data in terms of average carbon intensity.

• consolidate_co2.py: Consolidate emission data throughout the year of 2021
• consolidate_supply.py: Consolidate energy supply data throughout the year of 2021
