vSECClib (Supply Equipment Communication Controller Library) is a software stack that covers the high-level communication between the charging station and the electric vehicle. The stack already contains the entire protocol stream of smart charging according to ISO 15118 and DIN SPEC 70121. With the embedded software modules Vector supports the rapid development of smart AC or DC charging stations.
Simplified development of communication software for charging stations
ISO and DIN interfaces ready for implementation
Mature software component with high reliability
Reduced time to market
Standard conformance communication between the charging station and the vehicle ensured
Hardware independent C/C++ library, compatible with all Linux-based systems (under development: AUTOSAR compatibility)
Regular updates to meet standards under development
The software stack consists of different modules, each of which is assembled according to the charging specifications selected by the customer. Depending on the charging method (AC/DC), charging standard (ISO/DIN) and the authorization method [EIM (External Identification Means) or PnC (Plug and Charge)] the product will be configured per user.
Soon we will offer additional modules of the vSECClib in addition to the existing vehicle communication module (.CCS): An OCPP module (.OCPP), which performs the message handling between the controller and the backend; and a Power Electronics Protocol module (.PEP), which handles the communication to the power electronics via Ethernet and in the future also via CAN.
Feature Release vSECClib
The following features will be implemented in the next release of vSECClib.CCS:
Improved library interface in preparation for the ISO15118-20 upgrade
Improved error handling
Additional development and debugging functions
Future-proof software architecture
ISO 15118-20 Implementation
In addition, we are developing the implementation of ISO 15118-20 with the following advantages:
Prerequisite for new functionalities
Wireless Power Transfer (WPT) (prototype available ISO 15118-20 DIS)
Automated Connection Device (ACD)
Bidirectional Power Transfer (BPT)
Dynamic Control Mode (for additional services)
Improved error handling
Uninterrupted renegotiation during charging
TLS for all applications
