E-Mobility Providers (EMP) are companies that provide and operate the charging infrastructure for electric vehicles
. Electro Mobility Providers do not have their own charging infrastructure, but rent corresponding charging services from Charge Point Operators (CPO), who own and operate their own charging stations
. EMP providers make this charging infrastructure available to their customers. The e-mobility providers' offering is designed in such a way that the charging infrastructure can also be made available to customers of other EMP providers. This technology is called e-roaming and is provided by the Roaming Network Operator (RNO). Billing takes place between the CPO provider and the EMP provider.
