Other:

All products technical information has been transferred to separate datasheet documents

Updated manual to match DU011 specification

Version 2.8.4

Known issues:

When tabs that were dragged out of the main window are closed, the whole Control Panel can also close

Pulses per Distance Unit field is unused for now as Speed Sensor input is not functioning yet

GPI, GPO selection list not fully correct

User interface does not allow to enter high accuracy PSU divider value

Min User SoC range can be set higher than Max. Then user SoC is shown as 0% or 100%

Version 2.11.0

Feature:

Added support for CAN filter device

Fixes:

#7819 Added a status item for the improved "Distance left" value estimation algorithm

#7892 Fixed Battery Pack ID button display

Known issues:

#8094 When wire break is found the individual cell voltage shown in cells tab is not accurate

Version 2.8.5

Known issues:

Non-Clearable statistics not saved

BMS might reset during charging stages, reset period could be 1-2hrs

Wireless connectivity module only transmits data to a connected device, receiving will be added in a later firmware update

Main clock can drift and fall behind up to couple of minutes per day

Speed Sensor input is not functioning yet

No SoC PWM output functionality yet

Cell Wire Break protection deactivation delay is not as set

BMS reset needed after cell count configuration to clear wire break protection/indication

CAN Broadcast Period not accurate

Each Call Value not broadcasted

Charging restarts on max cell voltage drops below restart value

Out of boundary current is indicated as measured, not as incorrect reading

Wire break indicated correctly not in all cases

Version 2.8.4

Known issues:

Wireless connectivity module only transmits data to a connected device, receiving will be added in a later firmware update

Main clock can drift and fall behind up to couple of minutes per day

Speed Sensor input is not functioning yet

No SoC PWM output functionality yet

Cell Wire Break protection deactivation delay is not as set

Version 2.9

Features:

This is the first release for CCGM023

Fixes:

This is the first release for CCGM023

Known Issues:

---

Version 2.9.2

Fixes:

#8148 SOC algorithm fix

Known Issues:

#8094 When wire break is found some voltage calculations might not be fully correct

#8095 Wire break detection for LTO cells with higher voltages (~3.4V) is not accurate

#7485 In some situations entering L2 access (when L2 password is not set) can be complicated

Fixes

Value of 'Total Voltage' in Layout #4 was displayed incorrectly above 655 volts

Fixes

Value of 'Total Voltage' in Layout #4 was displayed incorrectly above 655 volts

Features

Default layout

This feature allows user to select desired display layout, which persist after power reset.

Ignition Sense

Display preview state will be controlled by ignition input status. When ignition input status becomes inactive - display is turned off and vice-versa. "Ignition" pin-function must be mapped in Control Unit

Changelog for version 1.2.2:

• Fixed a bug for Layout #5. When elapsed stage duration time was not converted properly to minutes. From now on this duration will have a range from 0 seconds to 9999 hours.
• Improved scaling of data value where a field is limited to a specific number of digits. E.g. 3 digits for “power” data value displayed in the image below.

  Previous Display Unit firmware versions: Emus BMS Display Unit v1.2.1 Release note archive: Emus BMS Display Unit firmware changelog

- Fixed a bug for Layout #5. When voltage value rose above 99.99 layout became not responding. Changelog for version 1.2.0: - Added new layout to "Energy storage" mode for monitoring internal and external temperatures. - From now on current, power and temperatures will be displayed with negative sign if necessary. - Parameters which do not have valid content will be displayed as invalid "-". - Some labels were redesigned. - Fixed display update rate bug, which happened due to frequent sentence transmission. - Increased display update rate.

Added J1939 chargers’ protocol
