Charger 2 (2. Generation) – Software Updates

New functions

• OCPP Open Backend: Now you can also control and configure the charger via the backend of third-party providers. You can restore the original Elli backend connection with a factory reset.
• Modbus server: You can now run the charger as a Modbus server, which allows you to control compatible Modbus-capable energy management systems.
• Display and control elements: Standby mode has been added. If there is no interaction after 120 seconds, standby mode is activated automatically (as long as no other activities are currently in progress, such as charging, updating, etc.). This is indicated by a blinking white LED in the center of the LED strip. Using this mode extends the service life of the LED.
• Resetting customer settings: Use this function to reset all customer settings. The factory settings (country, phase configuration, power limitations, etc.) will be preserved.
• Charging history: Now you can download the charging history as a CVS file. The file contains information that you can use e.g. for documentation or analytical purposes. Additional information is also available (such as most recently started charging with units, counter start, counter stop, authorization token).

Connectivity & Communication

• Charger connectivity: Upgrade to improve stability of Internet and backend connections
• Communication between the charger and backend: OCPP and other basic communication actions have been stabilized
• Internal energy management: Additional languages available
• Other general upgrades

Software & User interface

• Charger configuration: Data encryption has been enhanced via HTTPS access and country support, display of the system information is improved, general handling and PUK entry is optimized
• Software update: Upgrade to improve stability of software update process
• LED display: Upgrade to fix error in behavior and improve display
• Charger settings: Improved stability after factory reset
• Operating system: General upgrades to improve stability

Charging Functions & Energy Management

• Charging authorization: Upgrades to improve stability when charging via RFID card or Smart Charging
• Charging function: Improvements to phase switching and charging
• Charger settings: Improvements to default settings for PLC charging
• Controls: Upgrade to improve stability of control interface to network operator (Section 14a)
• Dynamic solar charging: Improved charging behavior and upgrade to improve stability when syncing values from Modbus meter
• Smart Charging: Update to improve detection of profiles and values
• Load management: Local functions are improved
• PV optimization: PV surplus charging can be activated via charger configuration
• Modbus counter whitelist: Counters compatible with IT grids have been added (Eastron SDM 630 IT grid and Siemens PAC 2200 IT grid)
• Phase switching: Function optimized
• Control interface to the grid operator (section 14a): In case of throttling, the reason for the charging restriction by the grid operator can be viewed in the charger configuration
• In rare cases, a bug fix may lead to an inconsistent configuration that prevents charging. In such cases, we perform a one-time manual correction through our internal backend. After that, charging can continue as usual.

System Stability & Security

• Troubleshooting: Update to improve error output/display as well as charging function and charger connectivity
• Certificate management: Update to improve stability of certificate renewal process
• Grounding monitoring: At delivery and after factory reset, this function is deactivated by default
