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.

Advantages

  • Universal controller for present and future electric vehicle charging use cases
  • High performance multi-core processor to cover further project-specific requirements
  • Compact industrial top-hat rail design for easy integration into a switching cabinet
  • Specified for industrial outdoor conditions
  • One device for all communication functions of the charging station
  • Turnkey solution: Immediate installation in the charging station
  • 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 charge management system

Application Areas

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.

Main Features

  • 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
  • SIL 2 capable in control pilot and proximity pin supervision

Roadmap

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

Please contact us if you are interested in further functions.
