DIGITAL ASSET PASSPORT

How It Works

DIGITAL TWIN: Digital representations of an asset are created on the EW blockchain using W3C DID technology and ERC1155 multi-token standard smart contracts.
MANUFACTURER: Manufacturers register energy assets with the platform by binding a digital identity to a physical asset.
INSTALLER: Installers, responsible for installing the energy asset, can easily retrieve the asset information by scanning the QR code on the asset and digitally sign a transaction that states they have installed the asset.
VERIFIER: Verifiers, responsible for making sure the energy asset is installed correctly, can easily retrieve the asset's information by scanning the QR code on the asset. Just like installers, they digitally sign a transaction that states they have approved the asset for being used.
OWNER: Asset owners register and provide details of their asset by scanning the QR code on the device and providing consent to the grid operator.
GRID OPERATOR: Grid operators receive a trigger that a new asset has been connected, verified, and activated. Unlike legacy processes, they don’t have to verify all the logistics; they can rely on digital trust provided by blockchain technology.

FREQUENTLY ASKED QUESTIONS

What is a DID?

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.

Why is EasyBat needed?

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 65
By 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.

What problem does EasyBat solve?

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.

Can I already use the application?

Yes! Our demo is already up and running. Click here to experience the EasyBat demo!

Is the application running on the EW Chain?

Since the EasyBat application is in beta phase, we are currently using the Energy Web testnet Volta.

Does EasyBat use EWT?

The Energy Web Token (EWT) will be used in the ecosystem to pay for gas fees and escrow for utility-layer services.
