Open EV Data

Open Dataset of Electric Vehicles and their specs.

In contrast to ICE cars, electric vehicles have very different behavious in terms of charging and charging speed. Hence having reliable data about a car is the key for developing EV-related applications.

This dataset (data/ev-data.json) can be freely integrated into ANY application. Mentioning Open EV Data as a source is appreciated!

This data is used for Kilowatt – Electric Car Timer app available on the Apple App Store.

It's a fork of the side project of the charging price and tariff comparison platform Chargeprice who stopped maintaining this project.

Available Data

At the moment mostly charging related data is available. Feel free to add more data if you need it!

• ID: Random UUID
• Brand
• Vehicle Type (car, motorbike)
• Type (BEH, PHEV)
• Model
• Release Year: Mainly to distinquish models with the same name.
• Variant: Bigger battery, optional faster on-board charger etc.
• Usable Battery Size: in kWh
• Average Energy Consumption: in kWh/100km
• AC Charger: Details about the on-board charger.
  • Usable Phases: No. of usable phases for AC charging. Allowed values: 1,2,3
  • Ports: Allowed values: type1, type2
  • Max Power: in kW
  • Power per Charging Point: Charging power at common charging points. Key and Value in kW.
• DC Charger: null if the car doesn't support DC charging
  • Ports: Allowed values: ccs, chademo, tesla_suc, tesla_ccs
  • Max Power: in kW
  • Charging Curve: Simplified charging behaviour based on various charging curve charts (e.g. Fastned). If no charging curve data is available, the default curve is assumed to be: 0%: 95% of max. DC power, 75%: max. DC power, 100%: max. AC power.
    • percentage: Charging level of battery in percentage
    • power: in kW
  • Is Default Charging Curve: true if the charging curve is based on the default curve instead of real measured data.

Change Requests

Please file an issue if you have a change request or reach out to hello@kilowatt.love

Contributing

The data is managed by Kilowatt via the Contentful CMS and is regularly updated. However we are always looking for people who want to contribute to the project! Feel free to contact hello@kilowatt.love in this case!

Updating the data

After you have published the data on Contentful, Open EV Data needs to get the changes as well.

Follow these steps:

Preconditions

• Have Ruby installed
• Have this project checked out
• Have contentful credentials available and stored in a scripts/.env file:

CONTENTFUL_ACCESS_TOKEN=<token>
CONTENTFUL_SPACE_ID=<space-id>

Running the script

1. cd scripts
2. Make sure bundler (bundle -v) is installed. If not: gem install bundler
3. Install dependencies: bundle install
4. ruby update_data.rb

Your changes should new appear in data/ev-data.json.

Pushing the changes

1. git commit -m "ADD charging curve of Aiways U5" (add a meaningful change message)
2. git push (push to master is fine)
