E-Mobility: The Future of Mobility is electric

The future of mobility is sustainable. No wonder, then, that hardly any other market is in as much flux as the one surrounding the topic of e-mobility. Innovation meets emerging regulations, international standards meet ever-increasing complexity.

Let’s set off together on the road to a modern, sustainable form of mobility.

Challenges and potentials for IoT in e-mobility

As specialists for outstanding IoT cloud solutions, scalable cloud architectures and topics such as Big Data, Data Science and AI, we join forces with you to meet the challenges on the way to a modern, sustainable kind of mobility.


In every area of IT, protocols ensure smooth and standardized communication between systems. Relevant in e-mobility are the international standards OCPP (Open Charge Point Protocol) and OCPI (Open Charge Point Interface), as well as MQTT, the IoT protocol that enables communication between charging station backend and a wide variety of devices and is becoming increasingly important, especially in combination with OCPP.

Monitoring & maintenance

Within an e-mobility system, a wide variety of users and applications are interlinked, and ideally these should be monitored, managed and (remotely) maintained as centrally as possible.

ISO 15118 /
Plug & Charge

The Plug & Charge function eliminates the need for charging cards or RFID chips during the charging process. The contract for the use of the corresponding charging station is directly linked to the e-car and enables direct billing.

Fleet management

E-mobility is also an issue for companies that offer company cars. Providers are faced with special challenges in this case, particularly with regard to on-site infrastructure and billing systems - for example, if reimbursement becomes necessary for employees who also use private charging stations.


In the field of e-mobility, various systems interlock. Especially when different stakeholders use a central backend, e.g. in the cloud, charging station operators must ensure that their customers' privacy is 100% guaranteed.


In order for e-mobility users to be able to use a broad charging station network, identification options, e.g. via RFID, must be ensured, a wide variety of operators must cooperate, and a platform must be used through which different systems can operate, such as Hubject or OCPI. Alternatives to roaming are ad hoc charging or micro-payments. Alternatives to roaming are ad hoc charging or micro-payments.

Calibration law

At the latest with the calibration law conformity coming into force at the end of 2020, special requirements will also be placed on charging stations for e-cars from the legal side. These relate in particular to the areas of billing, accounting and payment. Charging station operators must ensure that all relevant data, such as the amount of electricity charged, time periods and customer data, is recorded and stored in a tamper-proof manner in compliance with calibration law.


Micro-payment or ad hoc charging solutions are a more flexible variant to roaming. Instead of signing fixed contracts with a provider, e-mobilists have the option of using charging stations without prior registration and paying only for the respective charging process, e.g., by checking or credit card. In these scenarios, operators of charging stations and infrastructure face particular challenges - especially with regard to compliance with calibration laws.

Load and charge management

The increasing number of electric vehicles and the correspondingly increasing number of charging stations require precisely coordinated management: Load peaks, e.g. from wind energy, want to be well distributed so that the sustainably generated energy does not go to waste. Charging bottlenecks, on the other hand, should be prevented by targeted and centrally controlled charging management.


CPO and EMP refer to two different roles in e-mobility. CPO are the Charge Point Operators, the operators of the charging stations. EMP or EMSP are the e-mobility (service) providers and make the charging infrastructure accessible. Both are ideally well connected, as rarely does one provider combine both roles.


Billing comprises the processes around all billing modalities - e.g. billing of the electricity actually charged by the customer, but also billing between roaming partners or the users of the cloud, via which the entire e-mobility infrastructure is controlled.

Sector coupling

In the area of sector coupling, the term power-to-mobility plays a particularly important role for e-mobility. Power-to-mobility solutions enable electricity generated by wind power, for example, to be used directly or stored or integrated into intelligent load management.

Software updates

To ensure a secure e-mobility network, different devices with different software must interlock within a system. Software updates and maintenance therefore affect not only this one system, but each individual application and its components, and must be managed and carried out reliably accordingly.

Hyper charger

Hyper chargers are fast-charging stations that recharge electric vehicles within a very short time. This very high charging has implications not only for the load and charging segment, but also for the equipment and monitoring infrastructure, which poses challenges for charging station operators in particular.


In e-mobility, a wide variety of applications and systems must interoperate. Platforms and software used must ensure smooth communication, for example between different charging station operators, without friction losses.
