Release notes:

Application 5.4.1 

 

Charger Operations 

  • Discovery Phase: Prolonged the discovery phase at the start of a session from 20 to 40 seconds, ensuring it did not stop at 10 A. 

  • Current Measurement: Prevented re-measuring the maximum EV current when charging was paused. 

  • Load Guard Connection: Received updates on Load Guard connection status from Power Management, which were logged and reported as events. 

  • OCPP Reboot Reason: Unified internal enumerations for charging stop reasons to correctly report OCPP reboot reasons. 

  • OCPP BootNotification: Prevented the charger from responding to OCPP messages if the BootNotification was rejected. 

  • Authorization: Checked the identification expiration time during authorization. 

  • Log Management: Forced logs to flush to disk on power loss to avoid missing entries. 

  • PlugAndCharge: Fixed cases where the PlugAndCharge tag ID was sent incorrectly. 

  • Power Management Reconnection: Fixed reconnection failures to Power Management in some cases. 

Payter Integration 

  • Fixed rounding issues for values sent to Payter. 

  • Removed support for the HRK currency. 

Modbus 

  • Added virtual state 11 to the connectors controller status register (0, 100) to represent a "reserved" status. 

  • Removed the EVSE status register (52, 152). 

  • Fixed the update of the CC status register (0, 100) when disconnecting a cable. 

Settings 

  • Implemented the logic behind StopTransactionOnInvalidId and made it writable. 

  • Added CentralSystem.Client.StopTransactionOnInvalidId as an alias for StopTransactionOnInvalidId. 

  • Removed CentralSystem.Client.HeartbeatInterval. 

  • Updated HeartbeatInterval to report the currently active heartbeat interval instead of acting as an alias for CentralSystem.Client.HeartbeatInterval. 

 

Power Management 

  • Siemens 7KM2200 Support: Added support for Siemens 7KM2200 as a Load Guard. 

  • Compatibility Fixes: Fixed protocol issues that made version 5.4.1 incompatible with version 5.4. However, version 5.4.1 remained compatible with 5.3 and earlier versions. 

  • Resume Mechanism: Reworked the charger resume mechanism to address issues with Power Management reconnecting multiple chargers simultaneously. 

 

GUI 

  • Login Options: Adjusted icons and labels on the Login screen to provide more space for text beneath the icons. 

  • Connector Lock Screen: Added a new screen to indicate when the connector remained locked after charging while the cable was still inserted. 

 

Web 2.8.8 

  • Cluster Data: Displayed cluster data on the Brain's dashboard. 

  • Console Warnings: Fixed most warnings displayed in the browser's developer tools console. 

  • HRK Currency Removal: Removed the HRK currency from the system. 

  • Dashboard Changes: Removed building energy consumption data from the dashboard. 

  • Menu Language Fix: Fixed the duplication of languages in the left-hand menu. 

  • Max Current Display: Corrected the dashboard to display the session's max current as the sum of all phases. 

 

Connectors Controller 

INCH (v6.9) 

  • Cable Lock/Unlock: Fixed cable lock/unlock issues for older hardware (stations older than 19420xxx). 

  • Cable Detection: Reworked the cable detection mechanism. 

  • DC Leakage Test: Ignored DC leakage test commands when no leakage device was present. 

  • EVSE Paused State: Transitioned to the Paused by EVSE state when the current dropped below 6 A. 

  • Signal Analysis: Fixed "CP out of range" errors with improved signal analysis. 

  • PWM Generation: Generated PWM signals in the Preparing state. 

  • Watchdog Logic: Rewrote the watchdog logic for SOM restarts. 

  • PWM Disturbances: Increased ADC range tolerance for PWM disturbances, mitigating DiodeInCarMalfunction/Negative12VNotDetected errors. 

  • Plug Unlocking: Fixed plug unlocking in the Available state. 

  • Connector State Transitions: Adjusted state transitions after charging ended, moving from Charging Ended to Preparing and then to Available when disconnected from the EV but still connected to the charger. 

INCH DUO (v0.61) 

  • Cable Unlock: Fixed false positive cable unlock issues. 

  • Feedback Delay: Reduced feedback delay from 3000 ms to 500 ms. 

  • DC Leakage Test: Ignored DC leakage test commands when no leakage device was present. 

  • EVSE Paused State: Transitioned to the Paused by EVSE state if the current fell below 6 A. 

  • Plug Locking/Unlocking: Improved plug lock/unlock reliability by adding retries upon failure. 

  • Connector Unlocking: Prevented automatic unlocking of connectors in the Charging Ended state. 

  • ADC Level Adjustment: Adjusted ADC levels for better accuracy. 

  • Connector Welded Errors: Fixed false positive ConnectorWelded errors. 

 

 

System 5.0.9 

  • Bundled and updated the app to version 5.4.1. 

 

System 5.0.8
