vSECC: Communication Controller for High Power Charging Stations
What is vSECC?
vSECC (Supply Equipment Communication Controller) is a communication controller for charging stations. It serves as a communication interface between the electric vehicle, the charging station management system (CSMS) and the power electronics. vSECC supports charging communication over CCS, CHAdeMO and inverted or roof-mounted pantograph charging. It covers the communication protocols ISO 15118, DIN SPEC 70121, OppCharge and CHAdeMO.
Typical use cases for vSECC are high-power double dispenser charging stations in public areas, residential or company parking lots. vSECC is also suitable for both destination and opportunity charge points along with roof-mounted and inverted pantographs using an external WLAN module. Moreover, it supports Value-Added-Services, for example for the preconditioning of buses.
