In the e-mobility market, in addition to the chargers sold with the management service, there are also open charging stations offered by many well-known manufacturers. AUMS Elmo allows to work with them. The only requirement is that the charger provides OCPP communication (version 1.5 or 1.6). This allows the future owners of the charger to decide for themselves which charging station they want to purchase, and thanks to AUMS Elmo they can manage it and at the same time offer charging services independently, without intermediaries. The station operator can monitor the operating parameters of the charging station and its diagnostics.
