  • Integrate a ramp filter, used primary by EVCS's, instead of using a PID Filter for the charge power:

    • Sent charge power will increase steadily, by a configured rate if the singleton component EVCS Power is activated
  • Wrote new tests for EvcsController and EvcsCluster

  • Substantial changes in the EvcsCluster:

    • Changed code for minimum guaranteed power
    • Changed the handling of the maximum Power of an EVCS. It will use that value of the maximum for calculation, but the sent
      charge power will be like before
      (Some cars are reacting like this: setPower: 22 kW -> chargedPower: 11kW, setPower: 11kW -> chargedPower 7 kW, ... )
    • Added logic, to reduce the value calculated from the "maximum allowed discharge power" of the ess, to avoid certain jumps to
      zero, if the essSoc gets lower. In the future, this should be handled by each battery itself.
  • General changes in the energy calculation of OCPP EVCS's:

    • Depending on the charging station, it returns only the energy value of this charging session or the total session.
      Now we are calculating the always the other value, depending on the given
  • Fixed Issue EvcsController unable to set certain channel values from child evcs component #1197 (Send also a chargePowerRequest of 0 if charging is disabled)

  • Small bug fixes

Well done. It's not perfect, but a big improvement to 'develop'. Thanks!

This is not actually a PID filter, so it's a bit misleading.
