vSECC Controllers from Vector

Vector and AST International offer a solution for the development of DC charging stations

  • The software and charging controller manufacturer Vector and the sensor specialist AST International are offering a solution for the development of DC charging stations.
  • This aims to ensure the compatibility of the communication protocols of the Vector vSECC charging controller and the AST DC Meter.

According to Vector, the integration of energy meters requires a combination of different communication protocols and often presents charging station manufacturers with high development and integration costs. To speed up these development processes, the vSECC controllers from Vector now offer a plug-and-play solution with the AST DC Meters (direct current energy meters) for transmitting the energy values via Ethernet and/or RS-485 interface. Bidirectional charging processes are also recorded in compliance with calibration law and transmitted from the AST DC Meter to the payment system.

The vSECC Controllers (Supply Equipment Communication Controller) from Vector control the charging communication between electric vehicles, charging station components and backend systems. The common charging standards such as CCS (Combined Charging System), NACS (North American Charging Standard), CHAdeMO (Japanese Charging Consortium) and, most recently, MCS (Megawatt Charging System) are supported.

The product family certified for worldwide use currently comprises the following variants: the vSECC for fast charging stations with two charging points and pantographs, the compact vSECC.single for slim single charging points and the space-saving vSECC.single board for the development of wallboxes. The basis in each variant is the Linux-based vSECC software, which is pre-installed on all vSECC controllers.

AST DC Meter
The AST DC Meter is a solution for continuous measurement of high currents and voltages in charging stations.

For the continuously precise measurement of charging power, AST International offers product variants for fast charging stations up to 780 A, Megawatt Charging Systems (MCS) up to 1500 A and DC wallboxes up to 200 A, thus scaling compatibility to all areas of the DC charging infrastructure. Certified in accordance with German calibration law, the requirements of the European Measuring Instruments Directive (MID) and French calibration law, the AST DC Meters can be used in all countries. For use in North America, Underwriters Laboratories (UL) certification based on the safety requirements of UL 61010 has also been successfully completed.
