Universal Controllers for Intelligent Charging Stations
vSECC (Supply Equipment Communication Controller) and vSECC.single are universal controllers for smart charging stations. vSECC supports up to two charge points in different standards simultaneously. It is ideal for public high power chargers, whereas vSECC.single controls one charge point, a perfect fit for DC wallboxes or small single dispenser chargers.
The controllers serve as a communication interface between the electric vehicle (EV), the charging and load management back end and the power electronics (PE). The multitude of functional interfaces makes both charge control units widely applicable for the fast implementation of smart charging stations. The high-performance processors guarantee stable and reliable functionality.
The controllers use the .CCS and .P libraries from vSECClib for vehicle communication and .OCPP for communication with the backend.

White Paper
With DC Wallboxes Into The Electric Future
Mobility is shifting more and more towards electric, also in individual transport. But not only the development of the vehicle side is crucial. To become suitable for the mass market, the construction and successful operation of charging stations must progress further.
- AC wallboxes are ideal for charging at home, while DC fast chargers are preferred when on the road, but are these two options enough to adequately serve the emerging market?
- Many EV drivers only cover short distances every day. How can the expensive battery be used when the vehicle is parked?
- And what if AC charging is not sufficient for the range required by private individuals or fleet operators?
DC functionalities can provide the solution here: Read the new white paper to learn more about the applications and benefits of DC wallboxes!

vSECC enables electric vehicle charging communication over CCS (Combined Charging System), CHAdeMO (Japanese Charging Consortium) and Pantographs. By controlling up to two charge points in parallel, the controller is especially designed to meet the requirements of public or semi-public fast charging stations and controls the required high-level communication. This makes vSECC ideal for smart AC or DC double dispenser charging stations in public areas, residential or company parking lots.
With the support of OCPP 2.0.1, vSECC enables backend communication for fleet management as well as charging and load management. Featuring pantograph charging makes vSECC well suited for depot and opportunity charge points. In addition, the communication with a Value Added Service server is possible, e.g. for the preconditioning of buses in accordance with VDV261.

vSECC.single Board
Your Kick-Start into the DC Wallbox Market
vSECC.single Board is the series ready single version of the vSECC. It can operate one charging connector and its small form factor makes it particularly interesting for intelligent AC and DC wallboxes. Currently vSECC.single is available as a plug-on communication board (1), which can be used to build an integrated solution. Furthermore, the board can be wired together with a base board (2) and built into a housing. In the future, a full vSECC.single controller (3) in DIN rail housing will be available.
- Accelerates development and paves the way into the emerging DC wallbox market
- Covers all charging communication functions to the EV, backend and PE control
- Charging communication according to ISO 15118, DIN SPEC 70121 and in the future also CHAdeMO (Japanese Charging Consortium) or ChaoJi.
- Small form factor ideal for intelligent AC or DC wallboxes and single dispenser charging stations
- Maximum flexibility: Develop your own integrated solution with the vSECC.single plug-on board or simply use the full controller
- Simplifies the addition of charging communication intelligence to existing electronic components
- High performance iMX 8 processor
- Prepared for future use cases such as energy management integration and bi-directional charging
- Remote software updates for standard updates and feature enhancements via OCPP
- Supports OCPP 2.0.1 for more efficient error handling and configuration of the controller in the CSMS
Due to its compact design, the vSECC.single board is ideal for wallboxes or smaller charging stations with one connector. Therefore, the communication board is especially suitable for charging electric passenger cars at home or at work. Furthermore, it enables photovoltaic system manufacturers to easily enhance their product with charging communication intelligence. The controller enables microgrids to use the generated electricity in an efficient way for charging EVs.
The future full controller is very convenient for smaller charging stations or pantograph charge points in fleets and depots, if only one charge point can be implemented due to the vehicle size and cable lengths.

Roadmap
Further Development of vSECC and vSECC.single
At the moment, vSECC supports two charging interfaces from CCS Type 1 or 2 DC or one CCS 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 one interface for AC charging in addition to a CCS DC charger.
Currently, we are further developing vSECC.single Board to a full controller in DIN rail housing.
On the software side, we are working on:
- OCPP 1.6J
- Plug & Charge
- CCS AC charging
- ISO 15118-20 implementation with the additional functions
- Bidirectional Power Transfer (BPT)
- Automatic Charging Device (ACD)
- Wireless Power Transfer (WPT)
