Lately, there has been quite a lot of debate about the capacity of the grid all over the world. With tensions rising, many people are voicing their concerns in terms of the potential grid overburdening. However, while speaking about it, one must remember how complex the whole ecosystem is.

The global energy system is a vast and complex network that supplies energy to homes and businesses across the entire planet. It includes everything from power plants and transmission lines to distribution systems and end-use customers. At the heart of this system is energy management. This is the process of planning, controlling, and optimizing the use of energy resources to meet specific objectives. It involves countless operations making sure that the entirety runs smoothly.

Demand response is one of the technologies involved in grid’s proper operation. 

Per definition, demand response is a change in electricity consumption by consumers to help keep the supply and demand of electricity in balance. This can be done by either reducing or increasing their electricity usage depending on the needs of the grid.

Through demand response, utilities can reduce the need for investment in new generation capacity, as well as improve grid stability and resilience. For consumers, demand response programs can offer financial incentives and other benefits.

The whole technology, however slightly complicated at first glance, brings a whole plethora of benefits for both - energy consumers and the grid itself.

In our downloadable PDF, we shed light on all the important aspects of demand response:

As we move towards an era where oil will likely become less accessible or even regulated in some way due to global warming concerns and other issues such as pollution caused by fuel sources like coal fired power plants, 

electric vehicles are to become the transport of the future.

 With such a massive shift across all transportation branches, all hands on deck in terms of innovative solutions are needed.

Luckily, such industry ameliorations can be observed in every aspect there is to eMobility. From ever-enhancing electric cars with prolonged-battery lives to all kinds of charging facilities, eMobility is entering a whole new level.

Amongst these solutions, a big part is played by software and digital products. Namely, eRoaming, connected car data and smart charging are all here to stay and are only advancing at a speedy pace.

We have already covered eRoaming in one of our downloadable PDFs. To see more click 

A few definitions can be found in terms of what smart charging really is. Some of the widely circulating ones say:

Smart charging is a cloud-based technology that makes it possible to adjust how much energy is used by EVs based on the current state of the energy grid.

But what does it really mean in practice? One must look at smart charging as a complex, inter-connected ecosystem that enables real-time data exchange between:


Through smart charging, the charging stations may monitor, manage, and restrict the use of charging devices to optimize energy consumption. The optimization happens on the basis of collected data which gathers information such as:

renewable energy availability or lack thereof

Future-proof nature of smart charging allows for free-choice maneuvers in terms of the quality and quantity of features, leaving the room for any necessary add-ons. All that to ensure EVs will not pose a threat to the grid in times of high charging demand that’s likely to grow directly proportional to the growing popularity of electric cars.

careful monitoring of the energy consumption and thus, transferring the charging loads across available energy sources and adjusting the power accordingly. 

The shifts are to ensure the continuity of (untouched) energy flow for its other consumers, such as homes and facilities nearby.

Interoperability and standardization have become a big part of the EV transformation. As the industry evolves, more and more players come to the game, bringing new developments and ideas. With that, the entire ecosystem undergoes massive changes and it may get difficult to keep track of what’s happening.

That way, interoperability is critical for eMobility. 

Open standards are necessary to ensure that different types of electric vehicles can interoperate with each other and with the infrastructure that supports them, which is run by multiple CPOs and EMPs.

ISO 15118 is an international standard that defines the communication protocols and data structures used in electric vehicle charging. It specifies the two-way communication between Electric Vehicles (EV), including Battery Electric Vehicles and Plug-In Hybrid Electric Vehicles, and the Electric Vehicle Supply Equipment (EVSE).

Communication protocols and data structures

ISO 15118 is designed to be interoperable, meaning that EVs and EVSEs from different manufacturers should be able to communicate with each other. The standard is also designed to be scalable, so that it can be used for both residential and public charging stations.

It enables interoperability between electric vehicles and charging stations, and allows for sophisticated features such as billing based on time of use or energy consumption. ISO 15118 also provides a framework for charging station operators to manage access control and load balancing.

ISO 15118 is built upon Public Key Infrastructure (PKI)

, which means  electric vehicles can be identified and authenticated. This authentication can take place before, during or after a transaction.

The standard is built out of 8 parts, each defining a different aspect covered by ISO 15118 as a whole.

Certainly, roaming is something known to everyone at this point. However, what that has to do with eMobility?

Being a broad term for services allowing for connection outside of the usual network, roaming turns out to be an on-point solution for EV charging. With many players in the eMobility game (i.e. Charging Point Operators, eMobility Service Providers), some type of a connector is a must. Here’s exactly where eRoaming comes into play allowing for multi-dimensional connection between operators and EV drivers.

In short, eRoaming can be established via the use of hubs and protocols. A hub here can be an open platform which, after subscribing, can be used by many operators, who operate on common terms. This all happens in such a way that a certain charging pool introduced to a common hub can then be easily used by clients (EV drivers) of different providers. Such a solution allows electric vehicle users to charge their car across cities/countries with limited hussle.

In order to facilitate such a solution, the hubs developed their own open protocols, which are essentially responsible for the connection. They also define the functionalities of each eRoaming platform.

Amongst the existing hubs, we can differentiate three major ones. They all come with their own open standards and unify hundreds of CPOs and EMPs as well as millions of EV drivers.

The three biggest hubs and their protocols are:

(eMobility Inter-Operation Protocol - eMIP)

Apart from the proprietary protocols coming from hubs, it’s worth mentioning that there's also an independent one - 

Open Charge Point Interface Protocol (OCPI)

. It allows for eRoaming between the hubs as well as peer-to-peer connection.
