ChargyTS Desktop App

Chargy is a transparency software for the validation of secure and transparent e-mobility charging processes, as defined by the German Calibration Law ("Eichrecht") in combination with the Alternative Fuels Infrastructure Regulation (AFIR) of the European Commission and the European Digital Quality Infrastructure. The software allows you to verify the cryptographic signatures of energy measurements within charge detail records and comes with a couple of useful extentions to simplify the entire process for endusers and operators.

Benefits of Chargy

Chargy comes with meta data. True charging transparency is more than just signed smart meter values. Chargy allows you to group multiple signed smart meter values to entire charging sessions and to add additional meta data like EVSE information, geo coordinates, tariffs, ... within your backend in order to improve the user experience for the ev drivers.
Chargy is secure. Chargy implements a public key infrastructure for managing certificates of smart meters, EVSEs, charging stations, charging station operators and e-mobility providers. By this the ev driver will always retrieve the correct public key to verify a charging process automatically and without complicated manual lookups in external databases.
Chargy is platform agnostic. The entire software is available for desktop and smart phone operating systems and .NET. If you want ports to other platforms or programming languages, we will support your efforts.
Chargy is Open Source. In contrast to other vendors in e-mobility, we belief that true transparency is only trustworthy if the entire process and the required software is open and reusable under a fair copyleft license (AGPL).
Chargy is open for your contributions. We currently support adapters for the protocols of different charging station vendors like chargeIT mobility, ABL (OCMF), chargepoint. The certification at the Physikalisch-Technische Bundesanstalt (PTB) is provided by chargeIT mobility. If you want to add your protocol or a protocol adapter feel free to read the contributor license agreement and to send us a pull request.
Chargy is white label. If you are a supporter of the Chargy project you can even use the entire software project under the free Apache 2.0 license. This allows you to create proprietary forks implementing your own corporate design or to include Chargy as a library within your existing application (This limitation was introduced to avoid discussions with too many black sheeps in the e-mobility market. We are sorry...).
Chargy is accessible. For public sector bodies Chargy fully supports the EU directive 2016/2102 on the accessibility of websites and mobile applications and provides a context-sensitive feedback-mechanism and methods for dispute resolution.
