Hubject differentiates between two business roles for the market players in the electric mobility industry - on the one hand operators of charging infrastructure (CPO), and on the other providers of services of any kind in the field of electric mobility (EMP). All functions on the HBS are based upon contractual relationships between the three main roles – the eRoaming platform, the CPO Partner and the EMP Partner, which explains the slightly different functionalities.
The eRoaming platform has a role for itself. It coordinates the Web services and mediates between the partners. For example, the eRoaming platform can accept specific service type offers created by the CPO and EMP and generates offers which are forwarded to the CPO.
Charge Point Operators (CPOs) provide the charging infrastructure and control desk solutions, and manage the charging stations at their disposal. Their scope also includes maintenance and technical troubleshooting of the charging stations.
A CPO partner can integrate a sub CPO. The sub CPO uses the same backend as the superordinate CPO and has no rights of its own on the HBS. A CPO partner can have any number of sub CPOs as long as they have been registered beforehand on the HBS by the Hubject authorities.
eMobility Providers (EMP) are service providers which enable customers with existing contracts for example to charge their electric vehicle on their own or other’s charging infrastructure.
Like CPO Partners, EMP Partners can have sub partners. They can register sub partners who act on behalf of the superordinate EMP.
