All-in-one battery firmware revisions

BAAA0010 (17 June)

Firmware changes:

1) resolve the issue of SOC not adjusting when charging from PV

2) Static OCV optimization, improved self calibration

BAAA0009 (15 mar 2024)
firmware changes:
1. BMU Hibernate wait time extended from 10 to 30 mins
2. Optimise logic for RTC clock fail error
3. Optimise cell balance logic (Passive equalise).
4. Improve self calibration logic, for lower temperatures and currents. Now 10C and 6A charge required
5. Improve SOC calculation, to improve SOC tracking and capacity issues.
6. Allow Wake & Active from Grid, if hibernated due to low voltage.

BAAA0008 (07 Dec 2023)
1.CCS battery module compatability
2.Change the SOC estimation logic (Correct SOC issues)
3.Solve AIO can't force discharge
4.Solve AIO can't switch off (Cell balancing function)
5.Change the duty cycle of balance to 50% (Cell balancing function)

2,4 & 5 all assist with SOC reading and capacity

BAAA0007 (19 Sept 2023)

1. Add CAN packets to PCS
2. Improve SoC tracking to reduce liklehood of SoC error
3. Release the 0 limit of current collection above 0.2A
4. Change the charge and discharge overtemperature or undertemperature threshold

BAAA0006 (10 Jun 2023)

1.Handle the bug of voltage difference and temperature difference alarm;

2. Fixf current sampling anomalies;
3. Newly added, temperature collection routine;
4. Fix temperature readings on the cells, being incorrect cell number/reading;
5. Fix failure of insulation protection alarm;
6. More than 1000mV can be added to charge;
7. Add fast charging and discharge functions;
8. Newly added equalisation count clearing function;
9. SOC reading fix;
10. fix the failure of OCV table checking;

BAA0004 (10 May 2023)

1. Add the fault masking function.
2. The current collection fault is changed to the fault that cannot be automatically recovered.
3. Handle the failure to enable the 13S balance;

BAAA0004 (17 Apr 2023)

1. Add uploading and setting of adjust parameters;
2. Added the OCV enablement function.
3. Added the balancing time calculation function.
4. Added the reset function.
5. Added the function of restoring the default protection threshold.
6. 1AH and SOC: 1% corresponding function;
7. Optimize the bmu dynamic data change function.
8. Off-grid upgrade function;
9. Serial number high and low bit exchange;
