Software and charging controller manufacturer Vector and sensor specialist AST International are offering a joint solution for the development of DC charging stations, which ensures the compatibility of the communication protocols of the Vector vSECC (Supply Equipment Communication Controller) and the AST DC Meter.

For charging station manufacturers, this shortens development times and enables full integration.

The vSECC offers 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 recorded in compliance with calibration law and transmitted from the AST DC Meter to the payment system.

The vSECC handles communications between electric vehicles, charging station components and backend systems.

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.

“The partnership with AST simplifies the development processes of our customers, as they can rely on aligned communication between the vSECC charging controllers and AST DC Meters,” says Rebekka Jentzsch, product manager, vSECC Controller (Vector).

“Fast development processes for new and more powerful charging stations are crucial for the expansion of the charging infrastructure,” says Marvin Stoll, key account manager at AST International.

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. CCS (Combined Charging System), NACS (North American Charging Standard), CHAdeMO (Japanese Charging Consortium) and MCS (Megawatt Charging System) are supported.
