BMS24 is designed specially for LiPo & LiFePo4 battery pack applied to storage energy system and Electrical Vehicle including E-Motorcycle, E-Scooter and so on. The Battery Management System can measure or detect the battery voltage, cell voltage, charge & discharge current, battery temperature, and battery SOC (State of Charge), displayed with TFT color LCD.

Please read the entire manual of Battery Management System completely before using, to make sure you can use this device better and more safely.

1. Ensure the Battery Management System program and settings match the battery pack, otherwise the battery will be damaged and a dangerous situation may arise, especially for Lithium batteries, which may cause fire.

2. For battery management system application and for Electrical vehicle application will have many differences, please adjust those key parameters carefully, or contact us for more details.

3. Do not allow water, moisture, metal wires or other conductive material into the device.

4. Never charge or discharge any battery having evidence of leaking, expansion/swelling, damaged outer cover or case, color-change or distortion.

5. Do not try to charge “non-rechargeable” dry cells.

6. Do not mix batteries of different types, different capacities or from different manufacturers.

7. Do not exceed the battery manufacturer’s suggested maximum charge and discharge rates.

8. Carefully follow the battery pack manufacturer’s recommendations and safety advice.

Special Features

1. The BMS24 uses advanced ADC measurement technology, high accuracy, high voltage, and high current detection circuit, The maximum voltage measurement tolerance is within 5mV at up to 24S LiPo battery (102V)

2. Support regenerative braking, during braking operation can charge the batter pack and the discharge power (Wh) will decrease in response to the braking power

3. Charge/discharge current up to 600A. Bigger current can be customized

4. 1.2A per cell balance current is very useful for large-capacity battery packs, the feature can resume all cell voltage balance statuses in the shortest time. Over temperature protection make sure the system is safe during balance

5. BMS24 calculate and display the charge and discharge power (Wh), generally the battery rated power is rated voltage multiply rated battery capacity.

6. TFT LCD screen provides rich information including current, voltage,power,capacity,battery status,SOC andtemperature and so on.

7. BMS24 features maximal safety protection, within the range parameters can be set up, BMS24 will alarm and cutoff7charge or discharge according to users’ setup, out of range of parameters, and trigged absolute maximum ratings BMS24 will force to cutoff charge or discharge to prevent the battery from fire.

8. Minimize the power consumption by draw current from all cells or external power supply.

9. Dual power desian, the unit can be powered by all cells or external power supply.

10. Detect cell count at any time, and compare with the count detected when switch on first time. lf it is not uniformity, the the device will alarm and cutoff charge or discharge according to users’ setup, the feature can prevent any cell connection from loosing.

11. Sound alarm and LED alarm wil be triggered when any warning events happened, and then wait several seconds cut ofi or Don't cut off charge or discharge. The delay time can be programmed

12. Charge relay and discharge relay are controlled independently.

13. Two temperature sensors monitor battery temperature on different position

14. Supports upgrading the firmware program by USB port.

15.BMS24 provide users the maximal flexibility, key parameters can be programmed.

16. BMS24 display batery SOC or called battery gauge similar with car dashboard. Cell count, battery pack voltage and battery gauge (%) is displayed simultaneously

17. In case that the battery pack need not be charged and discharged, Press SToP buton enter into sleep mode to saveenergy consumption, at this mode, Charge and Discharge is forbidden, and LcD back light is off. Press any key toresume normal work mode.

18. LCD back light ON time can be programmed to save energy, when it is OFF, press any key to resume "ON"

Current Sensor Specifications

Please use correct curent shunt according to actual maximal charge and discharge current, singe shunt is enough for BMS2475mV or less shunt is suggested. It can provide all kinds of shunt. we calibrated cell voltage and current before delivery.The 300A and 600A 75mV specification is as below

Current Calibration

Press SET/START 3 seconds enter into Program Setup a d find the Current Calibration, you can calibrate the current toimprove the meas re acc racy, if exchange the current shunt, you must calibrate current again.

1. Shortly press SET/START make the 0A blinkT.

2. T rn off charge and discharge, and shortiy press SET/START button.

3. Press SET/START again and increase the calibration current to another value (up to 255) and charge or discharge

battery at the current.

4. Press SET/START save calibration data.

5. Press SET/START for 3 seconds quit Program Setup.
