Fikk svar fra selger av Heyo BMS på en del spesifikke spørsmål jeg hadde til settinger på BMS via PC. Legger de ut her som referanse da det gjerne er andre som lurer på det samme:
(Og da ble det plutselig logisk hvorfor vifta startet, dog kunne hjelpeteksten med fordel vært endret fra ‘battery chemistry’ til ‘MOS temperature fan start’ eller noe sånt..).

here is the reply , please check it:
-
What does pack status 4047 HEX indicate? Is there a table for these values? Same question for battery status and pack config.-----it's system preinstall , pls ignore it
-
Is the RemainingCapacity number calculated from Ah-counting or is it only based on SOC and Full Charge Capacity?------first time connection with PC program , it's Ah-counting,then it's the real capacity indication. please check the attched picture-1
-
Pack configuration is set to 5DC1 – is this correct for our battery? ---you can ignore it at it's defaulted
-
To the table with Voltage of Capacity xx % values: Is the SOC calculated directly from this table, or is SOC corrected for charge/discharge current which will lead to higher/lower voltages at the same SOC?---please refer to the above quastion 2
-
How is SOC reset/calibrated upon full charge? Is this manual or automatic? Can you point us to which settings that are critical to have a correct SOC?-- please do the calibration, charge to full and set is as 100%
-
What is the physical meaning of Charge Backup Current? Is a setting of 200 mA correct with this battery pack? ---pls ignore it , it doesnot change anything
-
We altered the Battery Chemistry ID from 002F to 0000 based on settings found in an English translation of the manual. Then the BMS fan was running constantly, so we reverted back to 002F. What is the correct setting?---it's Hexadecimal, if you change it to 0000, fan runs when it above 0 ℃; 002F means fan will run when it above 47°;
-
Our intention is to set an alarm limit on 3.63V cell voltage, which is released at 3.60V, and that BMS should disconnect from charging when cell voltage is 3.65V. Are our settings correct, or should the Over Voltage and the Charge end voltage values be switched?---please check the attached picture 2
-
What is a sensible value for the Charge End Current. 200 mA seems low for such a large battery pack? Please make recommendation.----pls igbore it
-
Our intention is to set an alarm limit on 2.93V cell voltage, which is released at 2.95V, and that BMS should disconnect load when cell voltage goes below 2.90V. Are our settings correct, or should the Under Voltage and the Discharge End Voltage values be switched?------ pls refers to the above question with pic 2
