Flea 4 SECC

Charge Controller
Flea 4 SECC is CarMedialab’s most up-to-date professional charging communications controller. It combines all nece­ssary charging and communication interfaces as well as supervision and analysis logs in a single system.

Intelligent charging communication

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. This reduces system complexity and integration costs. In addition, Remote Device Management makes it possible to communicate reliably, in accordance with industry standards, between the charging controller and the charge management system. This enables OTA software updates, a range of payment functions, control functions for operating and costs as well as Value Added Services.


CCS (Combined Charging System)

Both direct current and alternating current charging methods can be implemented with the standardized CCS connector system.

Panto Up

With Panto Up, the current collector is located on the vehicle roof and extends upwards in the direction of the charging station.

Panto Down

With Panto Down, the current guide is mounted on the infrastructure and lowers to the roof of the vehicle for charging.

Wireless power transfer

Non-conductive energy transmission through the means of inductive coils.

      Frequently Asked Questions
      What is ISO 15118?

      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 which way does ISO 15118 benefit to the charging process?
      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.
      What is Vehicle-2-Grid (V2G)?
      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.
      What is the latest version of ISO 15118?
      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.
      What does ISO 15118 consist of?
      ISO 15118 consists of several sub-documents, collectively defining a complete communication interface covering all procedural and technical layers.
      What is OCPP Compliance?

      Systems with communication interfaces which use the OCPP standard are considered OCPP compliant or OCPP conform. It means that different charging points can be linked to different central systems if they have all been developed to be OCPP compliant.

      In order to verify how compatible they are with other systems, CarMedialab regularly takes part in “testivals” where all of our product’s functions are examined and validated to ensure they comply with standard application.

      What role does ISO 15118 play in Smart Charging?
      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.
      Who needs to know about ISO 15118?
      • Vehicle manufacturers (OEM)
      • Charging infrastructure manufacturers and charging point operators (CPO)
      • E-mobility service providers (EMP)
      • Roaming platform providers (ROP)
      • flexibility marketers/service providers, and network operators.
      How does CarMedialab contribute to ISO 15118?

      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.

      What is OCPP?

      Open Charge Point Protocol

      What is OCPP 2.0.1?

      OCPP standard version 1.6 is the most widely used protocol in charging technology. Version 2.0.1 is a further development and is the latest version of the protocol.
