The Universal Control Unit for Intelligent Charging Stations
vSECC (Supply Equipment Communication Controller) is a universal controller for smart charging stations. The ECU 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.
Universal controller for present and future electric vehicle charging use cases according to ISO 15118 and DIN 70121
High performance multi-core processor to cover further project-specific requirements
One device for all communication functions of the charging station
Turnkey solution: Immediate installation in the charging station
Compact industrial DIN rail design for easy integration into a switching cabinet
Specified for industrial outdoor conditions
Functional Safety: Control pilot and proximity pin supervision designed for SIL 2
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

vSECC supports electric vehicle charging communication over CCS (Combined Charging System), CHAdeMO (Japanese Charging Consortium) and GB/T (Chinese Charging Standard). 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 backend 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 control unit 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 points in fleet depots, company parking lots, residential complexes, charging points for opportunity charging (e.g. wireless charging, pantographs with external WiFi module) or at semi-public/public fast charging stations.
Compliant with common electric vehicle charging standards
Supports OCPP 2.0.1 for the backend communication via Ethernet
Designed for parallel handling of up to two charging points
Vehicle identification possible via External Identification Means (EIM), RFID and Autocharge, therefore particularly suitable for fleet management
24 V industrial power supply
Control pilot and proximity pin supervision designed for SIL 2
Features under development
At the moment the controller supports 2 CCS Type 2 DC charging interfaces simultaneously.
In the future also it will be possible to use one interface for CHAdeMO, CCS type 1 and 2 DC and AC charging or GB/T in addition to a CCS Type 2 DC charger.
We are currently working on:
Control of the power electronics via CAN
Value Added Services
Connection to smart metering (in conformity with calibration law)
Implementation of the Japanese protocol CHAdeMO 1.2 and 2.0
Plug & Charge
CCS AC charging
CCS charging configurable via type 1 and type 2
Implementation of the Chinese protocol GB/T
Pantograph charging (inverted and roof-mounted)
ISO 15118-20 implementation with the additional functions
Bidirectional Power Transfer (BPT)
Automatic Charging Device (ACD)
Wireless Power Transfer (WPT)
PLC Debug Console to provide debug access to the vehicle communication
