Battery firmware revisions


This article will provide ongoing updates with any mass firmware releases with fixes, it will list the latest firmware from top to bottom.

BMS(3005) 08/12/2021

1:Increase the BMS chip equalization when the voltage difference of the cell is greater than 200mV in the operating state
2:Multiple battery pack balancing improvements

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------

BMS(3002) 15/10/2021

1: the overall low voltage alarm is changed from 41.6V to 45V, and the overall high voltage alarm is changed from 58.4V to 57.5V  
2: The battery balancing function is enabled 

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------

BMS(1041) 09/09/2021

1. High voltage alarm: two cells up to 3.65V or one cell up to 3.7V, protection value: two cells up to 3.7 or one cell up to 3.75
2. Low voltage alarm: two cells up to 2.6V or one cell up to 2.4V, protection value: two cells up to 2.3V or one cell up to 2.0V
3. The under voltage or overvoltage time was changed from 15s to 3s

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------

BMS(3001) 09/03/2021

1. Change the battery reaction to undervoltage or overvoltage to 1 second
2. five parallel battery optimization 

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------

BMS(1039) 09/03/2021

1. Increase the alarm conditions of overvoltage and under voltage of the battery. Overvoltage alarm requires two cells to reach 3.65, or one cell to reach 3.9,
while under voltage alarm means two cells to reach 2.6 or one cell to reach 2.3.
2. Increase the protection conditions of overvoltage and under voltage of the battery. Overvoltage alarm requires two cells to reach 3.75, or one cell to reach 4.0,
while under voltage alarm means two cells to reach 2.3 or one cell to reach 2.0.
3. There is a voltage difference of 800mV between the two neighbours, no alarm will be reported, and no value will be assigned to the full charging capacity.
The SOC will not change, and then charge and discharge after recovery.

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------

BMS(1037) 20/01/2021

1. Revision of version number
2. Increase whether to insert a flag on the USB flash disk
3. Added remote restart of battery function

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------

BMS(1036)
1.Battery overvoltage alarm changed from 3.6V to 3.65V.
2.The undervoltage and overvoltage time changed from 1s to 15s.
3.Optimized 80 %DOD calculations (previously only released 78 %).
4.Triggered low Pressure If no overpressure is triggered within 4 days, the low pressure mark will be removed.
