Emus EVGUI application for Android devices

Oct 13, 2016
View details

Changes in Emus EVGUI v1.5.8:

  • Removed Auto-Connect setting. The device will always connect to default Bluetooth module;
  • Removed ability to set MAC address in preferences. This functionality is not available;
  • Added Auto-Discovery setting, to automatically discover Emus Bluetooth device and connect to it (no more need for scanning and pairing);
  • Added text on Dashboard view, indicating Bluetooth connection status;
  • Added floating messages viewing for all windows;
  • Added connection pausing when the application is in the background;
  • Improved overall Bluetooth connectivity and handling;
  • Changed application icon to match Emus BMS product logo.

What’s new in 2.0.21.1 Control Unit firmware:

  • From now on Climate Control is not executed if min cell voltage is below Cell Under-Voltage protection “Activate at” threshold;
  • Speed signal measurement is now more accurate and in sync with current measurement. In result, momentary consumption and all three types of estimated distance left are more accurate too;
  • “Periodic Data Broadcast” function of the CAN bus parameters no longer needs to be enabled for the “Broadcast Each Cell Value” function to work;
  • TM4 Neuro CAN message sending is now included into build for all firmware types and is enabled by a newly added separate function;
  • “Charger Connected” protection that opens the main contactor automatically is charger is connected has been added;
  • Fixed bug where parameter could be changed during charging;
  • Pin mapping parameter can no longer be changed during charging, except when inverting the input pin mapped with “PF3 AC Sense Input” pin function, but only if “Non-CAN Charger” or “Analog Signal Controlled Charger” firmware is used;
  • Fixed bug where Control Unit would send login status over serial and CAN interfaces every 10 minutes;
  • Fixed another bug in the pre-charge procedure for Zivan RE chargers;
  • Fixed bug where “Protection event” charging error would sometimes be registered instead of “Overvoltage” charging error;
  • “Trips count” statistics now counts the number of times the charger has been connected when driven distance is more than zero;
  • Removed the unused Charger Type parameter;
  • “Pulses per distance unit” parameter now has a new ID and is 4 bytes instead of 2;
  • Implemented setting SOC over CAN;
  • Adjusted CAN bit timing setting for 1Mbps and 800kbps speeds in order to support longer bus lengths;
  • Fixed bug where cell detail requests would be stalled if a request for external temperatures is active, but no external temperature sensors are used. From now on cell detail requests for external temperatures timeout immediately if the corresponding battery flag is invalid;
  • Removed Balancing Range parameter and replaced it with Allowed Disbalance parameter;
  • Implemented second password which gives three access levels instead of two:
    * Level 2 access allows to change individual configuration parameters and perform all maintenance operations;
    * Level 1 access allows most maintenance operations, such as firmware updates, loading configuration from a file, resetting configuration to defaults, clearing the events log and statistics, resetting current measurement to 0, resetting the Control Unit, setting the SOC value, and calibrating the internal and external temperatures sensors of the cell modules, but does not allow changing individual configuration parameters;
    * Level 0 allows only activity monitoring but no maintenance operations or changes to the configuration;
    Logging in/out, as well as setting/clearing the password is done using the same serial protocol sentences or CAN messages as before (see Emus BMS Serial Protocol and Emus BMS CAN Protocol documents).
  • Parallel connected charger handing is now unified for all supported CAN charger types: Set Current is now divided by the “Number of Chargers” parameter before sending to each connected charger, meaning that “Slow Charging Current” and “Fast Charging Current” parameters define total current of all parallel connected CAN chargers, and if the actual number of connected chargers is less than the value of “Number of Chargers” parameter, Set Current will be respectively lower than the corresponding charging current parameter. This also means that Elcon related CS2, CS3, and CS4 sentences have been removed from Emus BMS Serial Protocol, and the number of connected Eltek Valere EV chargers does not have to be equal to “Number of Chargers” parameter for the charger connection to be acknowledged. Furthermore, Actual Current status is now accumulated from all connected chargers for all CAN charger types, number of connected chargers is now reported in the first field of CS1 sentence instead of charger connection status, and maximum number of parallel connected chargers is now 16 for all support CAN charger types;
  • General purpose output pin mapped with PF10 Charger Enable Output function is no longer enabled in Pre-heat stage.

Separate firmware image by supported charger type:

Emus BMS Control Unit firmware v2.0.21.1 Analog signal controlled charger – Includes support for analog signal controlled chargers without CAN interface (e.g. TC/Elcon chargers without CAN module);
Emus BMS Control Unit firmware v2.0.21.1 Elcon – Includes support for TC/Elcon chargers with CAN interface;
Emus BMS Control Unit firmware v2.0.21.1 Eltek Valere EV – Includes support for Eltek Valere/Valeo EV chargers with CAN interface;
Emus BMS Control Unit firmware v2.0.21.1 Non CAN Charger – Includes support for simple, “ON/OFF” signal controlled charging devices without CAN interface;
Emus BMS Control Unit firmware v2.0.21.1 Powerfinn – Includes support for Powerfinn Robust and Powerfinn PAP3200 chargers with CAN interface;
Emus BMS Control Unit firmware v2.0.21.1 Zivan Q9 – Includes support for Zivan Q9 series chargers (models SG3 and SG6) with CAN interface;
Emus BMS Control Unit firmware v2.0.21.1 Zivan RE – Includes support for Zivan RE series chargers (models NG1, NG3, NG5, NG7 and NG9) with CAN interface;

What’s new in 2.2.4.2 Control Panel firmware:

  • Updated Display Unit configuration dialog;
  • “Export Statistics” and “Import Statistics” actions are now disabled if not logged in;
  • Merged “Cells” and “Charger” tabs of Configuration page into a single “Charging tab”. Maximum Allowed Voltage, Balancing Range and Minimal Allowed Voltage widgets are hidden if Control Unit firmware version is greater than or equal to 2.0.21.0 since they are either populated elsewhere or the corresponding configuration parameter is no longer used;
  • Redrawn the charge curve image in order for it to reflect the actual parameter meaning more clearly, used less annoying color palette.  This modification is versioned, so if the firmware version of the connected Control Unit is older, the charge curve image and surrounding widgets are displayed in the way that is relevant to that version;
  • Made “Charger Type” parameter widget hidden if Control Unit version is equal to or greater than 2.0.21.0 and updated all related code accordingly, since this parameter is no longer used;
  • Added “Broadcast TM4 NEURO Messages” checkbox to the General tab of the Configuration page, since this is a separate function from Control Unit firmware version 2.0.21.0;
  • “Charger Connected” checkbox is now displayed in case Control Unit with firmware version 2.0.21.0 or higher is connected;
  • The looks of the Control Panel application window is now less dependent on the widget style of the operating system;
  • The interface for logging in/out and setting/clearing password has been updated to support the second password functionality that was introduced in Control Unit firmware version 2.0.21.0. The white background of the Update page icons has been removed for better looks, since this page is now disabled when logged out;
  • The widget of “Pulses Per Distance Unit” has been updated to support four byte long parameter instead of two byte long parameter, taking into account the change introduced in Control Unit firmware version 2.0.21.0;
  • Added “Number of Connected Chargers” status to the Charging Process groupbox in the General tab of the Status page taking into account the change introduced in Control Unit firmware version 2.0.21.0;
