The Universal Controller for Intelligent Charging Stations
vSECC (Supply Equipment Communication Controller) is a universal controller for smart charging stations. The controller serves as a communication interface between the electric vehicle (EV), the charging and load management system and the power electronics. The multitude of functional interfaces makes the vSECC a widely applicable control unit for the fast implementation of smart charging stations.
Based on a high-performance hardware (i.MX 6 Quad Core), the controller is suitable for generous application programming, e.g. for graphical user interfaces, certificate management or load management, e.g. for fast charging stations.

- Comprehensive security analysis based on ISO 15408, ISO 27001, IEC 62443
- Remote software updates via OCPP for standard conformity and functionality extensions
- OCPP 2.0.1 implementation for more efficient error handling and configuration of the charge controller in the charging management system
White Paper
Electric mobility is picking up speed: More and more OEMs are introducing electric vehicles for various purposes to the market. Financial subsidies are making it easier for vehicle owners to make the switch. Now we need the adequate charging infrastructure.
But what exactly does charging need to look like to be accepted by all customers?
In this white paper, you will learn:
- How intelligent fast charging is helping electric mobility achieve a breakthrough both privately and commercially
- Where and why AC charging is still used
- How charging station manufacturers are winning in the growth market of charging infrastructure with the right components

Application Areas
vSECC supports electric vehicle charging communication over CCS (Combined Charging System), CHAdeMO (Japanese Charging Consortium) and Pantograph. The controller handles the communication with the power electronics for direct current (DC) charging and controls the components for alternating current (AC) charging. The support of OCPP 2.0.1 enables back end communication for fleet management as well as charging and load management.
In addition, the communication with a Value Added Service Server is also possible via Ethernet, e.g. for the preconditioning of buses in accordance with VDV261. The controller is specially designed to meet the requirements of intelligent AC and DC charging stations and the required high-level communication. This makes the controller particularly suitable for the use at charging stations in bus or fleet depots, company parking lots, residential complexes, or at (semi) public fast charging stations. Moreover, opportunity charging is enabled with the Pantograph option (both roof-mounted and inverted pantographs, with external WLAN module).
Main Features
- Compliant with common electric vehicle charging standards
- Supports OCPP 2.0.1 for the back end communication via Ethernet
- Designed for parallel handling of up to two charging points
- Suitable for pantograph charging stations according to OppCharge and ISO 15118
-
Communication to power electronics via Ethernet and CAN
- Particularly suitable for fleet management: vehicle identification possible via External Identification Means (EIM), RFID, Autocharge, Plug & Charge ready
- 24 V industrial power supply
- Control pilot and proximity pin supervision designed for SIL 2
- vSECC uses the .CCS and .P libraries from vSECClib for vehicle communication and .OCPP for communication with the back end
Roadmap
Features under development
At the moment, the controller supports two charging interfaces from CCS Type 2 DC or one CCS Type 2 DC and one CHAdeMO interface simultaneously. Moreover, it is possible to use vSECC for inverted and roof-mounted pantograph charging stations.
In the future it will be an option to use to use one interface for CCS Type 1 and 2 DC or AC charging in addition to a CCS Type 2 DC charger.
We are currently working on:
- Plug & Charge
- CCS AC charging
- Connection to smart metering (in conformity with calibration law)
- Implementation of the Japanese protocol CHAdeMO 2.0
- ISO 15118-20 implementation with the additional functions
- Bidirectional Power Transfer (BPT)
- Automatic Charging Device (ACD)
- Wireless Power Transfer (WPT)
