Well-established team for Smart Charging: ISO 15118 and OCPP 2.0.1

Electromobility standards
ISO 15118 is responsible for communication between the charging station and an electric vehicle, OCPP for communication between the charging station and a central charging management system. They work hand in hand – and benefit from each other.

Why do the two standards rely on each other
Many charging systems use version 1.5 or 1.6 of OCPP. With ISO 15118 and the latest version of OCPP 2.0.1 in combination, the requested amount of energy is moreover sent to the charging station. This in turn forwards the information to the backend system. The two standards help make processes faster and easier for everyone. Without OCPP 2.0.1 and ISO 15118 additional hardware or a mobile app to send information is required.

Smart charging in context
The more data provided and the more accurate the data from the e-vehicles, the better the central system can make decisions. That’s exactly what smart charging is. Smart charging also helps avoid the notorious peak loads in order to save costs. In addition, vehicles are no longer charged with too little energy, other charging users do not unnecessarily block stations, and time-consuming alternatives are eliminated.

With Smart Charging peak loads are avoided

VDV 463 makes charge planning easy

The right interface determines your daily routine 
You don’t have time to plan and keep track of every charging process and every preconditioning request individually? Do you think it’s too time-consuming to constantly check the charge status of your buses? You are afraid that a bus will not make its tour with its current charge? Then VDV 463 might be just the solution you’re looking for, because it is a decisive interface to remove the stress around your daily operations.

The challenge with public transport becoming increasingly electric-powered lies with overall systems that enable comprehensive data exchange. Communication between the vehicle and the charging station (ISO 15118) and between the charging station and the Charge Management System (OCPP) has already been standardized, but there has not been a uniform format for the Charge Management System and the cross-modal pre-system. With a well-defined standard for communication, companies no longer have to develop their own solutions, which have long integration times and involve a lot of effort. This is exactly what VDV 463 is about: an interface between the Charge Management System and the Pre-Systems such as the Intermodal Transport Control System (ITCS) or the Depot Management System (BMS).

How VDV 463 works
How VDV 463 works

Functionality and application
The above mentioned systems using this interface acquire up-to-date data, which is continuously exchanged between the systems in both directions. The interface has been developed for three different use cases.

  1. Manage circulation and provide loading request from ITCS and BMS to Charge Management System: new request or charge request
  2. Control loading process and transfer information about loading processes from Charge Management System to ITCS
  3. Implement preconditioning request from Pre-System in Charge Management System and return current status

Your main advantages

  • Flexibility – open interface and thus no vendor lock-in
  • Ensure compatibility and thus simplify processes considerably

Why the OCPP standard is so important

Interfaces between vehicle, charging station and backend ensure further development of charging infrastructure.

When charging electric cars, several factors are important to ensure a fast and safe charging process. This must also fit seamlessly into the local energy supply. 

The Open Charge Point Protocol (OCPP) is the common language between charging stations and their management systems. It has become the de facto standard for electric car charging. When an electric car starts its charging process. A comprehensive data transfer begins between the charging point and the CPO/MSP backend system connected to it. User data can be transmitted to the contract partner as billing data for the charging current. The time frame and the amount of energy consumed for the respective charging process are also transferred.  

Vendor-neutral, license-free – the obvious solution for reliable and efficient management and control of the various tasks mentioned above. As a quality feature, the international partnership of over 160 electric mobility companies, Open Charge Alliance (OCA), added a certificate in 2019. This enables interested parties to immediately recognize whether a charging station is compatible with OCPP. CarMedialab is also a member of OCA. Currently, almost all leading manufacturers are looking to equip their charging stations with OCPP-compatible technology.  

What are the advantages of OCPP?
OCPP has a number of advantages over other standards and protocols. For example, charging stations can fully communicate with any OCPP-compliant CPO/MSC backend system, with data well protected. In this way, customers get a future-proof and cost-effective charging infrastructure. It can also be combined with additional software and hardware components from different manufacturers at any time. 

Up-to-dateness for use of all functionalities
It is important that the charging stations always use the latest version of the Open Charge Point protocol. This means that the core includes all services such as firmware management, smart charging, reservation, management of a local authorization list and remote triggering. All of this is provided with the current OCPP, which will be converted into an ISO standard in the future. 

All info about our software stack OCPP can be found here.

Get the Update: ISO 15118:20

A new version is released and will be available from CarMedialab this summer

ISO 15118:20 is an important communication standard that offers many new possibilities for electric vehicles.

This can be divided into four major functionality sections: 

  1. AC for alternating current charging
  2. DC for direct current charging
  3. wireless power transfer (WPT) for inductive charging and
  4. Automatic Connecting Device Pantograph for charging communication via pantograph charging infrastructure

Bidirectional charging represents a sought-after technical advancement in the new standard. It enables both the charging of a vehicle and the feeding of energy back into the grid.

OppCharge and Pantograph
Here, charging is done with so-called “Opportunity Charging”, among experts this is called: OppCharge. This refers to opportunity charging of the batteries of buses or trucks: With this technology, they are recharged with high energy at terminal stations or selected locations. The challenge here is to transfer a lot of energy in a short time. The connection is made by conductive poles and rails on the vehicle as well as Wifi communication and control within an automatic connection system. For charging, the pantograph is moved to the contact point on the roof of the vehicle. 

The charging process works

Successful acceptance test on site
With our valuable client we’ve performed successful acceptance test onsite. This was to verify that the application works as planned for the customer. Smart Charging from CarMedialab offers embedded systems that can be integrated into both the vehicle and the charging pole. For vehicle and charging pole to harmonize, software and hardware must be in perfect harmony. Our software stacks help to make this possible.

Good bus charging management is compatible with existing systems

Future-proof charging management thanks to VDV-Normen
Users of our charging management system MOBILEcharge benefit from the interoperability of the software to efficiently charge many electric buses. But what does that mean exactly?

Interoperability generally means that a system can work together with other systems. If the system’s interfaces are open, collaboration can work with two or more programs or systems. Thus, multiple systems can be integrated without problems of access or implementation.

Interoperability enables the integration of existing systems

At Rhein-Neckar-Verkehr GmbH (rnv) for example, e-buses, as well as passenger cars, are charged at four depots with over 100 charging points. Various interfaces ensure optimal functionality: VDV 463 between charging management and depot management system (DMS) at the customer’s site and VDV 261 for communication between charging management and vehicle to control preconditioning (Interior and battery are tempered in time). Compliance with these VDV standards enables a high degree of interoperability. GoRaleigh based in the USA also controls and monitors the charging activities of the e-buses with MOBILEcharge in connection with the control centre. Changes can be made permanent so that charging can always be carried out in a cost-saving manner.

Conveniently charge and monitor e-buses
Through our charging management system MOBILEcharge, all charging processes can not only be primarily controlled but also monitored in real-time. Charging with reduced amperage increases battery life while lowering overall energy demand.
