Decentralized identifiers (DIDs) are self-sovereign digital identities that can be created and stored independently from a central authority. Think of a DID as a universal and interoperable online account that the user controls and can be used to log in to any platform or service. DID technology enables https://www.w3.org/TR/did-core
With EasyBat, DIDs are used to represent a digital passport of an asset. This new type of identifier that enables verifiable, decentralized digital identity. A DID identifies any subject (e.g., a person, organization, thing, data model, abstract entity, etc.) that the controller of the DID decides that it identifies. In contrast to typical, federated identifiers, DIDs have been designed so that they may be decoupled from centralized registries, identity providers, and certificate authorities. Specifically, while other parties might be used to help enable the discovery of information related to a DID, the design enables the controller of a DID to prove control over it without requiring permission from any other party. DIDs are URIs that associate a DID subject with a DID document allowing trustable interactions associated with that subject.
EasyBat has the potential to unleash the acceleration of low-carbon, customer-centric electricity systems by enabling any energy asset owned by any customer to participate in any energy market.
Europe recently launched a regulation (2019/1020) concerning batteries and waste batteries, repealing Directive 2006/66/EC (https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CELEX:52020PC0798&from=EN
ARTICLE 65By 1 January 2026, each industrial battery and electric vehicle battery placed on the market or put into service and whose capacity is higher than 2 kWh shall have an electronic record (“battery passport”).
The battery passport shall be unique for each individual battery referred to in paragraph 1 and shall be identified through a unique identifier that the economic operator placing the battery on the market shall attribute to it and which shall be printed or engraved on it.
The battery passport shall be linked to the information about the basic characteristics of each battery type and model stored in the data sources of the System established pursuant to Article 64. The economic operator that places an industrial battery or an electric vehicle battery on the market shall ensure that the data included in the battery passport is accurate, complete and up-to-date.
The battery passport shall be accessible online, through electronic systems interoperable with the System established pursuant to Article 64.
The battery passport shall allow access to information about the values for performance and durability parameters referred to in Article 10(1), when the battery is placed on the market and when it is subject to changes in its status.
When the change in the status is due to repairing or repurposing activities, the responsibility for the battery record in the battery passport shall be transferred to the economic operator that is considered to place the industrial battery or the electric vehicle battery on the market or that puts it into service.
Simply put, EasyBat is a digital passport for batteries. It is a battery registration, tracking, and tracing solution with a modular, decentralized architecture that can be easily scaled into production.
Since the EasyBat application is in beta phase, we are currently using the Energy Web testnet Volta.
The Energy Web Token (EWT) will be used in the ecosystem to pay for gas fees and escrow for utility-layer services.
