Firmware for the TAO EMS master unit – refer to the user manual for the firmware update procedure.

 

29/10/2023 – v1.36: fix bug “missing events in event log” – clear events flags as soon as they have been read and do not reset triggers / output state when parameters are saved to EEPROM                                                                                                                                                                  WARNING: Monitor firmware needs to be updated to V 2.02.13 

 

04/08/2023 – v1.35: force read of parameters before changing some of them and saving (bug: cycle counter was changing without explanaition)

 

17/07/2023 – v1.34: corrected rare and random bug that prevented CANbus to re-enable the charge after the Charge Cycle Management feature reached the low SOC.  Monitor firmware has to be updated to 2.02.11

 

30/10/2022 – v1.33: added events when battery is empty and when battery capacity is calculated

 

26/03/2022 – v1.31: fixed issue #4 + added event when triggers and parameters are saved (issue #3)

 

11/02/2022 – v1.30: updated communication library, rewrite relay delay processes, disable CCM when a low voltage or SOC trigger is activated

 

27/12/2021 – v1.28: add out of range checks for current ADC measure and ignore negative SOC cycle time when millis() gets reset

 

15/11/2021 – v1.26: do not clear diagnostics results if an error is found / add a test for temperature sudden change

 

07/11/2021 – v1.25: add error codes that flash on the LED panel

 

05/09/2021 – v1.23b: add emergency and CCM flags to avoid relay reset by triggers, allow simulation balancing of single cell

 

14/08/2021 – v1.22: accept cell voltage measure only between 2 V and 5 V

 

06/08/2021 – v1.21: fix bug in battery efficiency calculation, use the “battery full” parameters in Charge Cycle Management when SOC max is 100% or a full charge is required

 

05/07/2021 – v1.18: add parameter for minimum cell voltage to enable balance (use BMSconfig v1.08 or above to edit that parameter)

 

v1.17: tidy up and minor bug fixes

 

v1.14: add features to match new monitor functionality (mainly events logging)

 

v1.12: improved internal resistance calculation, cell voltage must be above 3.3V to enable balance, minor bug fixes

 

v1.09: disable cell balancing when cell voltage is too low to ensure that cells are only top balanced (no balancing can take place if a cell voltage is under 3.10 volt)

 

v1.08: add possibility to activate relay output as a default as soon as the BMS is operational
