The document discusses the need for a new approach to open data integration for smart e-mobility applications. There are billions of data sources and formats from IoT devices that need to be integrated, verified and incentivized for use by data consumers and providers. A proposed solution is the Open Charging Cloud that would use blockchains and smart contracts to track data provenance, ensure transparency of updates, and facilitate micropayments to incentivize open data sharing. This could help applications like automatic vehicle charging and integrate renewable energy sources into the power grid.
