The ubitricity Mobile Metering concept rethinks infrastructure for electric vehicles and will revolutionize EV charging. Instead of installing complex electronics at every charging spot, users simply take metering technology along with them. Metering and billing is processed by electronics inside the car or the charging cable. Fully functional charging spots then require much less technology. ubitricity system sockets will be sufficient. Mobile electronics inside the car or the charging cable unlock the system socket, enable user and transaction based metering, and allow for precise billing. A smart solution for drivers and infrastructure providers alike.
