The Battery Passport showcases a seamless integration between real-time data from IoT devices and interactive applications stored on the portable blockchain. The sensors periodically transmit data related to the battery’s performance and condition, facilitating proactive maintenance planning and giving a new meaning to what we know today as battery end-of-life. Now, the used battery can be securely sold and reused in a different environment, where it can be utilized to its fullest.
To offer a more practical understanding of the entire process, we prepared a video demo that showcases how data is collected from the car, stored on blockchain, and then visualized by the end user in the Vehicle Passport.
In a real-world scenario, data is directly ingested using Era APIs. However, for the purpose of this demo, we are leveraging the Traent Era user interface and its features to better explain some key concepts.
As shown in the audit log, car data is integrated using Traent Streams. This feature allows for real-time continuous ingestion of data, stored on blockchain every 50-100 milliseconds. When considering the battery passport, we have the option to reduce the data rate in order to conserve storage space. However, in situations such as car telemetry, it becomes crucial to maintain higher data rates. Therefore, we empower customers to make informed decisions by providing sensible defaults that suit their specific needs.
Because all data is stored on a portable ledger, a car owner can decide to share with a buyer information about the number of recharging sessions while excluding sensitive data like the location of the charging stations used. During the sale of the car, the product passport can be shared and ownership transferred through a simple app.
Lastly, data from the portable ledger is shown in a tailor-made, interactive application based on the Traent Viewer technology. This provides a gateway to an array of functionalities: from live insights into the battery’s usage history and health to quick access to car functionalities.
