BMS battery pack protection board function description:

Support :

7S -24S li-ion battery (24V-102V Lithium battery cell)
8S -24S lifePo4 battery (24V-88V Lithium iron phosphate battery cell)
10S -24S LTO battery (24V-68V Lithium titanate battery cell)
The default is the li-ion parameters. when you phone connect bluetooth , can click and set up lifePo4 / LTO parameters
Single cell voltage detection range 1V-4.6V. High precision detection cell voltage error is less than 5MA
Charging current 50A
Discharge current: 70A 100A 150A 200A 300A to choose
Balance current :200MA . Controlled equalization mode, when the charging is started, the pressure difference can be detected by the detected pressure difference to be greater than the set value.
High-precision coulomb counter function temperature control detection Hall speed measurement

1. Protection board support 8-24 cells any battery pack (lithium titanate, iron lithium, ternary, Li-ion , Lipo,lifepo4 etc.) (greater than 18v)

2. Battery voltage detection, voltage detection range 1-5v (less than 1v and higher than 5v can not be detected), high precision, integrated error of less than 5mv, applicable to all the voltage within the scope of the battery pack used, overshoot Protection, over discharge protection voltage can be set within this range.

3. With a controlled equalization method, the charge can be balanced by detecting that the differential pressure is greater than the set value.

3. Current measurement (support within 300a current measurement)

4. High-precision coulometer function, based on the current on the time integral, accurate calculation of the remaining battery capacity, charge and so on.

5. Support Android phone set different battery parameters, see the single voltage and current information

6. Support the screen shows the battery status, parameters, each unit voltage

7. Based on the motor Hall pulse detection speed, and can calculate the remaining mileage

8. Independent 6-way temperature measurement, you can set the temperature over-temperature protection value

9. Dual independent watchdog real-time monitoring program plus two protection, never crash!

10. Screen power supply 24V-100V 11.Protection board size: Length 15.5CM    Width 7CM    Thickness 2.5CM

The balance wire connects the positive electrode + of the battery pack from the right to the left
1+ is the location of the first cell wire
2+ is the location of the second cell wire
If battery cell is not full enough 24S, ignore it
After connecting the wires, connect Bluetooth to set the battery parameters and the number of cells to use

temperature sensor connect :

include 4 temperature sensors and one 5P cord plug ( it don’t have effect if you don’t connect temperature sensors )
Picture ① Use scissors to cut the temperature sensor a bit
As shown② find two thin wires welded to the temperature sensor
③④ Put into the heat-shrinkable tube on the position where the four temperature sensors are welded.
⑤5P black wire is connected to one of the four temperature sensors wire , and the other four red wire match each temperature sensors .
Note : 5P wire is the common wire , and the other 4 wires are the T1 T2 T3 T4.
The 4 position temperature can be displayed on the mobile phone . don’t have difference between – and +
As shown ⑥, the temperature sensor must be insulated with a high temperature tape
Finally put the battery in 4 different locations, detect the temperature of the battery 4 locations
External temperature sensor can be connected to a maximum of 4 pieces, you can also connnect 1 pcs or 2 pcs or 3 pcs

include the screen+ protection board + wires and other kits

About starting and closing buttons:

1. If the protection board is turned off due to abnormal power failure, only a short press button is needed to start the normal operation of the BMS.

2. During the normal operation of the protection board, press and hold this button for more than 5 seconds, then release the button, the protection board will automatically turn off the power, stop working, zero power consumption, short press can realize the display of the matching screen of the switching protection board.

3. Protection board If the discharge tube is not turned on for more than 5 minutes, the protection board will automatically turn off the main power, stop working, and consume zero power.

4. If the BMS power supply is turned off for the reasons of the second and third conditions, press the power button for 3 seconds to start the normal operation of the protection board.

5. If a matching display is connected, short press this button to switch the screen display.

6. Power button Please ensure good insulation, otherwise it may not be able to automatically turn off the BMS power supply.

About onboard Bluetooth;

Bluetooth is turned on only when the mainboard is not in standby status. After 3 minutes the board is power on, board no current will enter standby status and Bluetooth will be turned off. Having the discharge or charging current , the system will cancel the standby status and Bluetooth will be turned on. You can observe the power led lights on both sides of the protection board. If they are always on, you can connect Bluetooth. If the system is standby, you can short press the protection board start button to activate Bluetooth once. Or re-start the protection board to activate Bluetooth. Make sure Bluetooth is turned on. In the phone’s system settings Bluetooth settings, search for Bluetooth devices. Search once without searching. Please search multiple times. The name (BMS_ANT) sometimes shows null, click the pairing password 1234. Open the APP you download and click Connect the device, select the device you just paired to connect

Protection board calibration:

1. Single cell voltage calibration: You can adjust the “system reference voltage” (the default is about 3.0) to slowly increase the size of 0.001, turn down, you can change the unit voltage value until accurate!

2. Total pressure calibration: You can adjust the “total pressure calibration parameter” (the default is about 3330), slowly adjust the size of this value, you can change the total pressure until accurate!

3. Current calibration: You can adjust the “current sensor range”, slowly adjust the size of this value, you can change the current until accurate!

Note: Do not change the “Power Start Current” item in the parameter setting. If it is too large, it may result in burning and discharging the MOS transistor! ! !

About the automatic balance function:

The auto-balance function is mainly a function that sets the battery’s difference too much. Users must use it when the battery is fully charged or nearly fully charged. When the battery is fully charged, unplug the charger and click ” Auto balance, at this time, the protection board will automatically balance until the battery pack voltagge difference is less than 0.001, or the user clicks on “automatic balance” again to turn off, whether the automatic balance is turned on or off can switch the screen to “system state” to view “balance “Status. If “Auto balance ” is displayed, it means that the automatic balance is in progress!
