ubitricity has developed a highly efficient solution to make charging and billing of green electricity affordable everywhere.The ubitricity Mobile Charging System offers the first possibility to roll out scalable charging infrastructure everywhere. To this end, ubitricity has developed an intelligent charging cable which entails all metering and billing technology: the SmartCable. The user carries the mobile electricity contract, tied to the SmartCable, along to the charging spot. The technologically lean charging spots produce next to no running costs. They can be installed practically everywhere: at a wall, integrated into a standing pole or even integrated into urban furniture such as street lights. The user portal offers (among other services) a transparent overview of all transaction data. The charging and transaction data is managed by ubitricity. The all-round service is completed by the monthly invoice.
