NG-Firmware version 7.4.0

• Added the possibility to reset the owner password back to the default password via OCPP using the configuration key PW-ResetChargerPassword.

• Added the possibility for a temporary user to change and reset the owner password. This allows for a CPO to set a temporary password and allow a local engineer to access the firmware without requiring Secure Service Access.

• Added the possibility to update to the bootloader to an earlier version than the current version in case it is determined that the current bootloader is corrupted.

• Added the possibility to erase personal data such as transactions, passwords, certificates, keys, local/white list, charging profiles and log data using our applications.

• Added the possibility for either an AFIR compliant disclaimer or a non-AFIR compliant disclaimer. The AFIR compliant disclaimer states “Only applicable for ad-hoc charging”, the non-AFIR compliant disclaimer states “Additional costs may apply”. For this purpose a new OCPP configuration key Pricing-ShowComponent is introduced with the options disclaimer-NonAfir and disclaimer-Afir.

• Added the possibility to permanently lock a charging cable to Eve Single S-line or Eve Single Pro-line charging stations equipped with a socket, using the configuration key “Connector1-Type” or Alfen Service Installer configuration item “Connector type” through the “Power settings”-menu (tick the “Advanced settings” checkbox). 
  
  Important notice: Alfen cannot be held accountable for any water ingress or subsequent damage to the electrical socket as a result of this application.

Improvements

• Improved the switching sequence of the onboard relays. The relays now switch simultaneously instead of sequentially.

• Added a new error code (error 215) to account for a loss of communication between the charging station and an external Modbus RTU energy meter.

• Stability improvements to Smart Charging Network

• Improved the distribution of available current when combining Active Load Balancing and Smart Charging Network

• Cybersecurity improvements

• DigiCert root certificates are added

Bug fixes

• Fixed an issue where the error message relating to a defective relay (error 102) was not permanent and the charging station went out of the relay error state despite there being a defective relay.

• Fixed an issue where the ACE Service Installer did not update the displayed current/voltage values of the individual phases correctly after changing the phase mapping.

• Fixed an issue where updating firmware of multiple NFC readers in one charging station failed. In case of multiple NFC readers there will now be updated sequentially.

• Fixed an issue where disabling the cover lock on an Eve Double PG-line with a custom display logo caused an inconsistency in the user interface.

• Fixed an issue where a double socket charging station with two feeder cables in a Smart Charging Network was limited in current when both sockets are occupied. Now the default maximum station current (StationMaxCurrent) is set proportionally to the amount of sockets after a reboot.

• Fixed an issue where the modem continuously tried to initialize during an active connection. Now if the charger has an active 4G connection or utilizes ethernet for connectivity the modem will not re-initialize.

• Fixed an issue where stopping the transaction caused by an RCD trip on an Eve Double PG-line caused an error with the signed meter data

• Fixed an issue where setting the maximum current of a sub SCN was limited by the maximum socket current. Now the maximum current of the SCN (which the subgroup is a part of) enforces the limit for the maximum current of the corresponding sub SCN.

• Fixed an issue where the charging station would not transition from suspendedEV to suspendedEVSE when charging is suspended.

• Fixed an issue where the meter values were incorrectly passed through in Wh instead of kWh

• Fixed an issue where the lockout timing was passed through in milliseconds instead of seconds to the ACE Service Installer

• Fixed an issue where the charging station returns an unknown error message in the ACE Service Installer after entering an invalid owner password

• Fixed an issue where setting up a back-office connection while a charging session is ongoing would crash a specific hardware revision of the Eve Double Pro-line. The charging station will now go into Inoperative mode when a download is ongoing and not download during a charging session.

• Fixed an issue where the SessionId incremented within the same Eichrecht transaction.

Back-office communication changes

• Fixed an issue where the charging station replied incorrectly to an out of range value for a RemoteStartTransaction. It now reports back an PropertyConstraintViolation after receiving such an out of range value, where previously the charging station reported a Format Violation in this situation.

• Fixed an issue regarding smart charging using charging profiles, where the lowest current of the TxDefaultProfile was obeyed while applying a TxProfile. The default profile is no longer overruling TxProfile even in case of a lower maximum limit.

• Added logging to detect a failed GetDiagnostic request when using an LTE network.

• Fixed an issue where the configuration of meter values was rejected when no phase was specified in the request. If no phase is specified the charging station determines if it can report it as multiple values per phase. If this is the case it will report these values to the back-office.

• Fixed an issue where the unit of measurand Energy.Active.Import.Register is inconsistently reported in either Wh or kWh. Now Energy.Active.Import.Register is reported in kWh by default.

• Fixed an issue where the charging station did not report when a reboot is required (RebootRequired) after a configuration change.

• Fixed an issue where the charging station would try to connect to a higher network profile during a firmware update, which could cause the update to fail. The charging station will now not connect to a higher priority network profile during an update.

• When a back-office requests a StatusNotification, the charging station will now confirm acceptance of the request or that the request is pending acceptance.

• Fixed an issue where the charging station would not clear a Faulted
   

Our Smart Charging Network (SCN) functionality is implemented as a shared library between our NG9xx platform and AHP platform to enable cross compatible SCNs. 
Our previous NG9xx release and our latest AHP releases have implemented SCN version 1.4, where this release newly implements SCN version 1.5. 
SCN versions are not backwards compatible. It is not possible to combine charging stations running this release together with charging stations running older NG9 firmware and/or current AHP firmware in a single Smart Charging Network. The ACE Service Installer will provide a warning if charging stations with different SCN library versions are used in one SCN. Please refer to the SCN compatibility matrix below to check compatible firmware versions. 
For the most current status on this topic please refer to our Knowledge Base.

Firmware update instructions

With the release of NG9xx Firmware 7.0, there is no longer the option between "A and B firmware versions", as first introduced with version 4.14.0.
To update to this release, please follow the advised steps according to our release notes page (NG)
