G3 battery

BMS3 - 4007 28 May 2024
1. Add Mixed G1 & G3 battery compatibility

 

 

BMS3 - 4006 (Internal release)
1. Overcurrent and short circuit do not clear the pre-charge flag during parallel operation.
2. When off-grid and low SOC, optimization of reconnection issues
3. Remote upgrade problem optimization: filter out energy storage machine resend information; close the file system when the system restarts; fix the problem that the upgrade light keeps flashing when the remote upgrade is interrupted; increase the U disk recognition capacity space
4. Modify the following strategy after SOC calibration (consistent with BMS2.0)
5. Add 9.5G3 beast mode function code

 

BMS3 - 4005 (Internal Release)

 

1. Optimize the static OCV calibration: increase the discharge static SOC-MAP value; shield the conditions for repeated calibration of small currents in static OCV calibration; modify the conditions for static current to less than 1A
2. Added can-485 mixed use automatic identification code
3. Add static calibration at charging end
4. Add dynamic SOC calibration
5. 9.5 Battery Full Charge Capacity and Design Capacity Processing
6. Add SOP-MAP function code
7. Added the ability to shut down the discharge MOS when the low SOC is less than 4% when the low-temperature charging MOS fails.
8. Optimize the problem of no charging when activated when the voltage is very low.
9. When adding RTC exception, the RTC time processing will not be updated.
10. 4005 code software review modification

 

BMS3 - 4004 (26 Jan 2024) - Factory Release

 

1. Update RTC time and add 485 configuration slave clock
2. Set the temperature 4 to battery core temperature detection. The NTC fault increases from 60°C to 65°C, staggering 5°C from the discharge high temperature protection.
3. Added fault storage (black box) function; added black box data U disk export function (yellow light will appear when exporting)
4. Battery CAN parallel connection optimization: optimize can communication parallel connection code
5. Optimize parallel SOC to 100% SOP strategy
6. Added beast mode code (currently 5.12G3C project)
7. Optimize the hardware watchdog code: time during the task process and reset after 15S
8. Optimize the short circuit problem when the voltage difference between parallel batteries is large.
9. When increasing parallel machines, the current limit value does not exceed the current processing requested by a single system.
10. Added single board test code
