Abstract
We present a suitable approach to address the electric vehicle charging
roaming problem (e-roaming). Blockchain technologies are applied to
support the identity management process of users charging their vehicles
and to record energy transactions securely. At the same time, off-chain
cloud-based storage is used to record the transaction details. A user
wallet settled on a mobile application stores user verified credentials;
a backend application in the vehicle charging station validates the
user credentials to authorize the energy transaction. The current model
can be applied to similar contexts where the user may be required to
keep several credentials from different providers to authenticate
digital transactions.
