Drivers of e-vehicles expect charging to work easily. For vehicle and charging point to harmonize, software and hardware need to be perfectly coordinated. CarMedialab develops state-of-the-art technology for standard-compliant communication between charging point and vehicle.
Very short implementation time of the software stack.
High quality due to proven application.
Use our experience instead of going through an expensive and lengthy process.
Connection to numerous backends already done.
By getting the source code, it is possible to continue working independently at any time without CarMedialab.
Our Software Stack is worldwide in use and tested.
You purchase a company license. This entitles you to use and sell the software on your hardware as part of your product for an unlimited period of time, regionally and quantitatively, but not exclusively.
You receive the source code. The programming language used is C/ C++ – the platform is Embedded Linux and x86 Linux.
A valid maintenance contract entitles you to receive updates for bug fixes, optimizations and more. If new versions of the underlying standards are adopted by the OCPP Protocol or ISO 15118/IEC 15118 and you have a valid maintenance contract, you can purchase an upgrade.
The software stack ISO 15118 consists of a compilation of source code, libraries and scripts.
CarMedialab develops continuously – so the software always meets the latest requirements.

Minimum requirements for your platform
We are a member of the Open Charge Alliance.
CarMedialab is a pioneer in Smart Charging. More than 10 years ago we contributed to the first development of a “Powerline” based smart charge communication protocol.
We offer you the right software – for both conductive und inductive charging. Your advantage: all components have been repeatedly tested and are already successfully in use. Plus, our systems are available immediately.
International Standard – “Road Vehicles – Vehicle to Grid Communication Interface”. ISO 15118 is a collection of international technical standards that define a high-level communication interface for charging purposes. This standard finds broad utilization in modern electric vehicles (EVs). Thus, eEVs as well as electric vehicle supply equipments (EVSEs) are required to conform the ISO 15118 standard.
In general, global acceptance of ISO 15118 not only enables all EVs and EVSEs to work interoperable, but it accelerates the development of charging technology drastically.
The charging process is automatically started or ended by connecting or disconnecting the charging cable, whereby the necessary contract information for authentication and billing of the charging electricity is exchanged. The act of entering a credit card, opening an app to scan a QR code, or finding that easy-to-lose RFID card is a thing of the past with this technology. For this, a corresponding charging certificate from an e-mobility provider must be stored in the vehicle (contract-based charging).
Vehicle-to-grid — integrating EVs into the grid. ISO 15118 enables the integration of EVs into the smart grid. A smart grid is an electrical grid that interconnects energy producers, consumers, and grid components like transformers by means of information and communication technology.
The latest publication ISO 15118-20 from beginning of 2022 contributes as 2nd generation network and application layer standards. In short, it renews the previous definitions mainly in the manners of additional functionality, security and connectivity interfaces.
ISO 15118 consists of several sub-documents, collectively defining a complete communication interface covering all procedural and technical layers.
ISO 15118 can be described as the enabler for smart charging measurements. In other words, ISO 15118’s continuous data exchange between EV and EVSE, paired with the possibility to dynamically influence the charging process, allows Smart Charging activies of all kinds.
CarMedialab offers productive and field-approved hardware and software solutions conforming the ISO 15118 standard. Developing not only our ISO 15118 software stack, but also our own EV/EVSE communication controller hardware, we can offer detailed knowledge to all aspects of high-level charging communication.
With our products, we cover all ISO-OSI layers 0-7. Consequently, we can provide ready to charge communication controller solutions.
We would be glad to assist you in integrating the device or the stack.
You receive a company license with the source code and libraries. This grants you authorization to use the software on your desired hardware platform.
It is not permitted to resell the software.

Why electric driving is coming to the fore in light of rising gasoline prices. In addition to the purchase price, there are other factors that come into play.
To get a non-emission fueled car moving, you need energy. This energy we can harness from the sun or wind and store in batteries, which we then can use to propel our cars. There are many ways to do this, but why not choose the simpler way, with less steps from energy source to consumer?
