How well do you know the EV charging ecosystem?

Carge EV charging ecosystem

Every single electric vehicle driver who wants to learn more about the e-Mobility can easily seek info into the EV charging ecosystem. Apart from the Electricity Provider and the Charge Point Operator, there are also businesses that are evolved to each charging session.

Based on the image above, let’s see some of the terms and their relation.

First things first, you may already know the term EV which means Electric Vehicle.

CSO (Charging Station Owner):

All businesses that allow the installation of charging infrastructure in their premises so that EVs can charge their batteries.


CPO (Charge Point Operator):

Mobility Partners that manage the charging infrastructure in terms of installation, operation, and service thereof. Most CPOs give access to their chargers via RFID/NFC tags.

eMSP (eMobility Service Provider):

The eMSP has an equally key role in the interoperability of the publicly accessible charge points. An eMSP often communicates directly with the back-end software of each CPO. However, it can also be connected to Roaming Platforms (the so-called HUBs as we will see below), in order to ensure cross-border charging for a seamless driver experience.

In fact, eMSP has a dual role. On the one hand, it has to exchange data with all charging networks, while on the other hand to provide the appropriate experience to the EV driver. This experience concerns both finding stations, as well as the support in matters of charging and payment. That being said, since we mentioned the payments, the money transaction is included in the procedures of an eMSP. The cost of each charge includes possible parking costs, infrastructure installation/maintenance costs, and of course the price of the electricity consumption. These are collected by the eMSP and then distributed accordingly to the partners (CSO, CPO, Roaming Platform, Electricity Supplier).

Carge is the first eMSP in SE Europe.

HUB (Roaming Platform):

After taking a look at the main mobility partners, it’s time to talk about HUBs, also known as Roaming Platforms. The concept behind HUBs is the connection between CPOs & eMSPs through data exchange. HUB’s role is important for the interoperability of the charging infrastructure and the cross-border charging at all. HUBs also provide analytics that help Electricity Providers manage the consumption spikes accordingly.

It’s possible that you might have some questions after reading about the roles of the EV charging ecosystem. Let us answer some of them:


– Can a CPO operate as CSO at the same time?

> Yes, a lot of CPOs usually operate as CSOs, by managing an area with or without restricted parking access.


– Can an Electricity Provider operate as CPO at the same time?

> Yes, there are some cases where Electricity Providers get the role of CPO, by installing the appropriate infrastructure on several locations.


– What is the purpose of a HUB?

> HUBs simplify the connection between CPOs & eMSPs, by giving seamless access to the EV drivers so that they can charge their vehicle anywhere. Apart from that, HUBs provide multiple pricing plans for the CPOs that will help drivers find the best charging rates through an eMSP application.


– How am I supposed to get the RFID card, if I register to a CPO app while I’m in front of a charger?

> Last-minute registration is not helpful at all. In order to get the RFID card on time, we highly recommend registering proactively a few days before your scheduled route. That said, you can not complete a charging session without being registered to the CPO’s platform that will send you the RFID card. For this reason, EV drivers have to check in advance all the accessible charging stations. Otherwise, they can easily use an eMSP app, even a few minutes before charging.


– Why should I use an eMSP, like Carge?

> An eMSP application gives access to all charging point networks, by comparing rates and searching availability in real-time. Additionally, if you use an eMSP app, you can charge your car without being registered to multiple CPOs and having with you multiple RFID cards. The most important is that EV drivers can view valuable information about electricity costs, charging behavior, battery health, etc. only through one platform. 

Now that you learned more about the EV charging ecosystem, it’s time to take a look at the FAQ section, where we have compiled a list of answers to common questions.
