8. Click [Copy]to copy this string of characters from the chip ID and send it to the merchant. The mer- chant will reply to you with a string of characters in the same format. Copy and paste the charact- ers given by the merchant into [Administrator Permission Verification]and click [Verify],the device permission will display 9. At this time,you can modify the new 5-level permission password. The administrator’s 9-level permission is a dynam- ic password,which will become invalid after one operation. (You can also clear the running time, protection records and other information of the BMS)

2.2 Quick Setup

4.3V high voltage cell setting
First set the ternary lithium parameters with one click,and then modify the following parameters based on the ternary lithium parameters:
1.In [Voltage Parameters]:
Single unit overvoltage protection is modified to 4.3v The cell voltage recovery is modified to 4.2v,
The single secondary overvoltage protection is modified to 4.4v The monomer secondary overvoltage recovery is modified to 4.3v,
2.In [Equilibrium Parameters]:
The balance limit voltage is modified to 4.3v,
The balanced starting control voltage is modified to 4.2v during charging,
3.In [Battery Pack Parameters]:
The capacity calibration method is modified to 3,

2.3 Voltage parameters

All the following protection information can automatically change the value according to the cell type set with one click,and also supports manual modification of the protection value range (non-professionals,without obtaining reasonable and valid data,please do not manually modify detailed parameters without authorization to avoid danger.!Our company will not be responsible for any danger caused by unauthorized tampering with parameters.)
In total, there are 26 wires in the individual cell sampling wire harness and BMS power supply wire harness.

Take the ternary lithium parameters set in the picture as an example↓:

1. During the charging process,when the voltage of any string reaches this value,charging will stop and the power-off protection will not affect the discharge use (can be called first-level overvolt- age protection,with the largest protection weight). After protection,the voltage will generally be reduced. For example,when the ternary battery is charged to 4.2v and dropped to about 4.17 v;when iron lithium is charged to 3.65v and dropped to about 3.4v,it is normal(the amount of voltage reduction depends on many factors of the battery itself)
2. After the cell overvoltage protection is triggered, the protection can be released and the charging function can be restored only when the voltage and power consumption of all cells drops below this value.
3. Reaching this value indicates that the cell voltage has exceeded the first-level overvoltage protection. At this time,the power supply will be cut off and we are not allowed to use the charging and discharging functions. The protection can only be released by solving the second-level overvoltage protection. Secondary overvoltage protection reminds us that we must pay attention to it and check what causes the voltage to be instantly too high. Under normal circumstances,secondary overvoltage protection is not allowed (except for 4.35V high-voltage ternary batteries).
4. After the secondary overvoltage protection is triggered,the protection can only be released when the voltage returns below this value.
5. You can fill in the value based on the maximum value of the battery cell*the number of battery strings. The default value is 103.2V(which can be called three-level overvoltage protection). The parameters do not need to be modified because there is a first-level monomer overvoltage priority protection.
6. After the total voltage overvoltage protection is triggered,the protection can only be released when the voltage returns below this value.
7. During the discharge process,when the voltage of any string reaches this value,the discharge will stop and the power-off protection will not affect the battery charging. (It can be called first-level undervoltage protection,with the largest protection weight). The voltage will rise after protection, which is the same as the voltage reduction when fully charged.
8. After the cell undervoltage protection is triggered,the protection can be released and the discharge function can be restored only when the voltage of all cells returns to above this value.
9. Reaching this value indicates that the cell voltage has been lower than the first-level under-voltage protection. At this time,the power-off protection will occur,and we are not allowed to use the charging and discharging functions. The protection can be released only by solving the second-level under-voltage protection. Secondary undervoltage protection reminds us that we must pay attention to it and check what causes the voltage to drop too much instantly. Under normal circumstances, secondary undervoltage protection is not allowed.
10. After the secondary undervoltage protection is triggered,the protection can only be released when the voltage returns to above this value.
11. You can fill in the value based on the lowest limit value of the battery cell*the number of battery strings. The default is 1.0v(can be called the third-level undervoltage protection). This parameter does not need to be modified because there is a first-level single unit undervoltage priority protection.
12. After the total voltage undervoltage protection is triggered,the protection can only be released when the voltage returns to above this value.
13. If the cell pressure difference exceeds this value, the pressure difference protection will be displa- yed;at this time,the power will be cut off and we will not be allowed to use the charging and disch- arging functions.
14. After the voltage difference protection is triggered,the protection can only be released when the cell voltage difference returns to within this value.
15. The voltage alarm parameters corresponding to this column can be displayed in the [Real-time Status]alarm column. The alarm information only serves as a reminder.

2.4 Temperature parameters

1. During the charging process,if the external battery temperature sensor detects that the battery temperature reaches 60℃,it will display the battery charging over-temperature protection. At this time,the power will be cut off and we will not be allowed to use the charging and discharging functions.
2. After triggering the battery high-temperature charging protection,the protection can only be released when the temperature drops below 55℃.
3. During the discharge process,if the external battery temperature sensor detects that the battery temperature reaches 60℃,it will display the battery discharge over-temperature protection. At this time,the power will be cut off and we will not be allowed to use the charging and discharging functions.
4. After triggering the battery high-temperature discharge protection,the protection can only be released when the temperature drops below 55℃.
5. During the charging process,the external battery temperature sensor detects that the battery temperature reaches -2℃ and will display the battery charging low temperature protection. At this time,the power will be cut off and we will not be allowed to use the charging and discharging functions.
6. After triggering the battery low-temperature charging protection,the protection can only be released when the temperature rises above 2℃.
7. During the discharge process,the external battery temperature sensor detects that the battery temperature reaches -10℃ and will display the battery discharge low temperature protection. At this time,the power will be cut off and we are not allowed to use the charging and discharging functions.
8. After triggering the battery low-temperature discharge protection,the protection can only be released when the temperature rises above -5℃.
*The above battery temperature protection parameters are only valid when connected to an external battery temperature sensor. Those without an external battery temperature sensor can be ignored. (T1,T2,T3,and T4 are displayed in the temperature area of the real-time status page to indicate the battery temperature. If no external temperature sensor is connected,the default display is -40℃. If the temperature sensor is extruded and deformed in the battery box,causing temperature detection errors,False protection,you can check how to shield [Battery Temperature Sensor Shielding]in [System Parameters]).
9. It is controlled by the built-in power temperature sensor of the protection board;regardless of charging or discharging,the greater the current and the closer to the power value of the protection board,the faster the temperature rises. When the MOS temperature reaches 80℃,the powerover-temperature protection will be displayed. At this time,the Power outage protection does not allow us to use the charging and discharging functions (triggering power high temperature protection means that the purchase options for the protection board are small and there is not much margin)
10. After triggering the power high temperature protection,the protection can be released only when the temperature drops below 65℃(if you want to release the protection quickly,you can manually adjust it to 70℃).
11. The voltage alarm parameters corresponding to this column can be displayed in the [Real-time Status]alarm column. The alarm information only serves as a reminder.

2.5 Current parameters

Non-professionals,please do not modify detailed parameters without obtaining reasonable and effective data to avoid danger!Our company will not be responsible for any danger caused by unauthorized tampering with overcurrent parameters!
Different current models have different parameter values Take the current parameters of the 24-string 130A [peak 325A]model as an example↓
1. Indicates that the charging current exceeds 50A and lasts for more than 5 seconds,and the charging overcurrent protection will be triggered.
2. When the protection board detects that the discharge current is greater than 200A and lasts for more than 5 seconds,the discharge overcurrent protection will be triggered (can be called level 1 overcurrent protection,with the largest protection weight and priority to trigger protection). Why is the nominal 130A[peak value 325A]set like this? Because the load may generally reach 200-300A 1-2 seconds before starting, so we set a 5-second delay for the 200A overcurrent protection. There is a high probability that the protection will not be triggered. The protection board is rated at 130A and can support 130A or less for a long time if heat dissipation is done well. current,and ensure that there is a certain margin (ensure that there is enough margin for loading,climbing,and turning on the air condition er in summer). Otherwise,the greater the continuous current,the greater the heat generated by the power MOS. When the temperature of the power MOS reaches 80°C,it will When the power over-temperature protection is triggered,the power protection will be cut off and we are not allowed to use the charging and discharging functions. The protection can be released only when the temperature drops below 65℃.
3. When the protection board detects that the discharge current is greater than 300A and lasts for more than 1000MS (1 second),it will trigger the level 2 discharge overcurrent protection. Why do we need a level 2 discharge protection when thereis already level 1 protection? If the protection board selection is too small,you can more intuitively see the level 2 protection triggered and record the current reached. The purpose is to remind us that we must pay attention to it and further analyze whether we need to replace the protection board with a larger current. Level 2 overcurrent protection is not allowed under normal circumstances
4. When the protection board detects that the short-circuit current is greater than 450A and exceeds 1200US=0.0012 seconds,the short-circuit protection will be triggered. At this time,the power will be cut off and we will not be allowed to use the charging and discharging functions.
Release protection conditions:Disconnect the load that consumes battery power.
The short-circuit protection detected by the protection board is triggered at the microsecond level by an instantaneous large current. The system current measurement time is 1 second,which is tens of thousands of times different. Therefore, short-circuit protection occurs in many cases,but the APP displays the current as 0. Since the load is such as There is a large capacitor inside the vehicle controller (the voltage across the capacitor cannot change suddenly). When the positive and negative electrodes are directly connected to the battery,a very large current will be generated,usually hundreds or even thousands of amps.
This problem can also be solved by adjusting the short-circuit protection delay. The smaller the short-circuit delay is(meaning the shorter the time), the higher the detection sensitivity when short-circuit protection actually occurs. However,the instantaneous high current that charges the capa- citor at power-on increases the probability of triggering short-circuit protection. On the contrary, the larger the short-circuit protection delay is adjusted(meaning the longer the time),the lower the detection sensitivity will be,and the lower the success rate when a short circuit actually occurs. The probability of malfunction is also lower. Therefore,increasing the short-circuit delay mainly affects the sensitivity when short-circuit protection actually occurs,and has no impact on other operations of the system. If you often encounter short-circuit protection,it is recommended to increase the short-circuit protection delay by 200 each time until the short-circuit protection is no longer accidentally triggered,and then increase it by 500. This will not only prevent malfunctions, but also ensure that a short circuit actually occurs. time success rate.
5. The overcurrent alarm parameters corresponding to this column can be displayed in the [Real-time Status]alarm column. The alarm information only serves as a reminder
6. SOC is the estimated battery charge percentage in real-time state.
Set the physical capacity and full charge cycle, and the SOC percentage will be automatically calibrated.
When the remaining percentage of SOC power reaches 20%,a SOC level 1 alarm will be displayed, and there will be no power outage protection due to SOC alarm problems.
When the remaining percentage of SOC power reaches 5%,a SOC level two alarm will be displayed,and there will be no power outage protection due to SOC alarm problems.

2.6 Equilibrium parameters

1. Cell voltages higher than this value will force the balance to open,which is called balance limit vo- ltage. If limit balance occurs in real-time,it means that the cell voltage has exceeded the normal cell overvoltage protection value. This reminds us that we must pay attention and check whether What causes the cell voltage to exceed the normal protection value. Under normal circumstances, extreme equilibrium is not allowed.
2. During the charging process,the balancing that is turned on when the cell voltage is higher than this value is called charging balancing(during the charging process,conditions ③and ⑥must be met at the same time before balancing can be turned on during charging).
3. During charging,the voltage difference is greater than this value(one of the conditions).
4. When balancing is turned on,balancing will stop,when the cell pressure difference reaches below this value.
5. 180N means that the balancing effect is 100%. If set to 90,the balancing effect is 50%(depending on the ability of the BMS hardware to support the maximum balancing current. The balancing current of all models of ant protection boards is basically 100MA, The balancing current of 10-24 strings is 200MA,the balancing current of 32 strings is 280MA)
6. During the charging process,the charging current must be less than this value and below 10A (one of the conditions)
To manually turn on the automatic equalization function:
On the BMS control page,you can manually click the [Turn on automatic balancing] and [Turn off autom- atic balancing] functions,which can be operated when the battery is not charged or discharged.

2.7 Battery parameters

1. You can choose to set ternary,iron lithium,titanium lithium,and sodium electricity parameters with one click.
2. Set the corresponding number of series according in series.
3. Ignore,please do not modify without authorization.
4. If the battery is not used for a long time,it will automatically shut down for protection due to the self-consumption of battery power and the selfconsumption of power of the protective board,which consumes battery power and causes the cell voltage to reach 2.9V.
5. Ignore,please do not modify without authorization.
6. Set the actual total capacity of the battery pack according to the amp-hour capacity. Only by setting capacity the BMS can you know the maximum capacity value of the battery pack.
7. Under the premise of setting the physical capacity for example,the current available capacity of the battery is about 20AH,set it to 20,which is used to calibrate the remaining capacity percentage. It is basically usable without setting this parameter. Do not set this parameter when the percentage power display is accurate.
8. lgnore,please do not modify without authorization.
9. This is a basis for judging the remaining power percentage of COS. For example,when ternary lithium is fully charged to 4.2V,the voltage will be reduced to about 4.17V. If the BMS detects that the ternary lithium cell voltage is4.17v,it will be estimated that the power is 100%. A voltage of 4.053v will be estimated as 90%of the battery capacity. If it is a ternary lithium battery,set the physical capacity and let it sit for 10 minutes,it will automatically calibrate the remaining battery percentage. Fully charged will be regarded as 100%. If the pressure difference is large,the corresponding percentage of electricity will be reduced according to the size of the pressure difference. The amount of electricity consumed will be reduced according to the corresponding proportion.
10. lgnore,please do not modify without authorization.
11. If the connecting piece of series connected batteries between each string of lithium batteries is inconsistent in thickness and length,the corresponding batte ry may have a greater resistance. When the entire battery set is being charged,the voltage of the battery string with a larger resistance will always be higher than that of the other batteries. Voltage,after stopping charging,the voltage remains consistent with other voltages. The same is true fordischarge. The larger the current,the more obvious it is. You can compensate by setting the corresponding connection internal resistance. For example,the voltage of the 10th battery string is always 0.5 higher than other voltages every time it is charged. After V stops charging,it becomes consistent with other voltages. You can set the internal resistance of the 10th string to compensate. First set it to 2 and then observe the voltage jump to see if it is significantly reduced. Then set it to 4 and so on,until the internal resistance reaches the 10th level. Until the string voltage does not jump,the function of connecting the internal resistance can only be fine-tuned. If the internal resistance is too large,it can only be solved by the battery itself.

1. If the current detected by the BMS is not accurate with the actual value,you can use this value. Each time you increase or decrease it by 10,the current will become larger and smaller accordingly. Repeatedly modify the value to check the current until the displayed current is equal to the actual current. You need to Use a highprecision multimeter to measure,and the error range is within 5%.As shown in the figure,the thick blue wire at the B-end of the BMS is a shunt that detects current. Different types of shunts on the BMS have different shunts. If you remove the original wire and re-solder it,be sure to pay attention that the welding wire or solder cannot exceed this line. wire,otherwise it will affect the current detection accuracy. A trace amount of solder can adjust the parameter calibration. If the soldering wire exceeds the safety line or there is too much solder,a new shunt needs to be replaced.
2. If the BMS is not charged or discharged after being turned on,it will enter sleep mode after 1800 seconds. Sleep will only turn off Bluetooth,not shut down. When the protective board detects charging or discharging current,it will wake up Bluetooth immediately. (The length of standby time can be modified),standby can reduce the power consumption of the protection board.
3. Change the Bluetooth address number:it can only be numbers without letters,for example,change it to numbers 1 or 2 or 3 in order. After modifying the Bluetooth address,Bluetooth will be disconnected immediately. You need to re-search for the Bluetooth name with the corresponding code to reconnect to Bluetooth. This parameter is specifically for those who have many BMS of the same model in order to make it easier to find the BMS corresponding to the Bluetooth name.
4. lgnore,please do not modify without authorization.
5. If an external battery temperature sensor is connected,if the temperature sensor is shaken,squeezed,deformed and damaged in the battery compartment,resulting in inaccurate temperature,the ‘battery high temperature’or’battery low temperature’protection will be mistakenly triggered.
To block the T1 temperature sensor,set the number 1
To block the T2 temperature sensor,set the number 2
To block the T3 temperature sensor,set the number 4
To block the T4 temperature sensor,set the number 8
If you want to shield T1 and T4,add the shielding numbers 1 and 8=9 and set them in.
If you want to block all 4,add the numbers 1248 =15 and set them in.
6. System sensitive parameters,please do not modify without authorization.
7. The password for levels 1-4 is 8 digits, Level 5 password is 12 digits,
Enter a new password in the corresponding level password,click [Settings]and then click [Save Application Parameters]above to successfully change the password. You need to verify the password for level 5 permissions first,and the permission 5 can be displayed before you can change it.
