The Smart Solution for Charging Communication

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. 

Advantages

  • 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

Components

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.

 

Feature Roadmap

Additional Modules

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
  • Stability improvements
  • Future-proof software architecture
  • AUTOSAR compatibility

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)
  • Multiplexed communication
  • Improved error handling
  • Uninterrupted renegotiation during charging
  • Multi-contract handling
  • TLS for all applications
