5.3.4. EvseSlac

This is an implementation of the ISO 15118-3 EVSE side SLAC protocol. The general flow of operation will be like this:

  • start of operation begins with a control pilot transition from state A, E or F to Bx, Cx or Dx. This is indicated by the EvseManager by calling the commands enter_bcd/leave_bcd.

  • Once started, it waits for a CM_SLAC_PARM_REQ from the EV side to start the SLAC session.

  • In case of success, SLAC finishes with a CM_SLAC_MATCH_RES, which sends a new NMK to the EV side. The EV then joins the logical network and the two modems are paired. A dlink_ready(true) is published to signal to the EvseManager that the low level PLC link is ready for communication.

If not run as root user, this modules requires the capability CAP_NET_RAW.

5.3.5. Todo

  • make use of the enable flag in the reset command or drop it, if not needed

  • handle CM_VALIDATE.REQ message

  • implement PLC chip resetting after unplug or failed SLAC sessions (especially for QCA chips)
