Chargery BMS24T is designed special for LiPo & LiFe&LiTo battery pack applied to storage energy system and Electrical Vehicle including E-Motorcycle, E-Scooter and so on. The unit 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.

Special Features:

1. The BMS24 uses advanced ADC measurement technology, high accuracy, high voltage and high current detection circuit. The maximum voltage measurements tolerance is within 8mV 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 to response to the braking power.
3. Charge/discharge current up to 600A.
4. 1.2A per cell balance current is very useful for large capacity battery pack, the feature can resume all cell
   voltage balance status at the shortest time. Over temperature protection make sure the system safety
   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 that provides rich information including current, voltage, power, capacity, control status, SOC and temperature and so on.
7. BMS24 features a maximal safety protection, within the range parameters can be setup, BMS24 will alarm and cutoff charge 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 design, 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. If it is not uniformity, 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 will be triggered when any warning events happened, and then wait several seconds cut off or NOT 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 location.
14. Supports upgrading the firmware program by USB port.
15. BMS24 provide users the maximal flexibility, key parameters can be programmed.
16. BMS24 display battery 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 button enter into sleep mode to save energy consumption. Charge and Discharge is cut off, LCD back light is off. Press any key to resume 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”.

Over 600A cusrrent customized is available.

The relay driven delay time board is optional, to restrain surge current when battery discharge to motor, the board can close a small current relay first and then close a large curren relay after a programmabl delay time.

if work with DCC, don't need install the board.

The 100V DC contactor is optional. the power consumption is only 11mA

On BMS16 V2.0,BMS8T v3.0 and BMS16T v3.0, the relay controller output 12V 3A to drive the relay whatever the battery type and cell count. The relay rated current should be chose according to the maximal discharge or charge current. Generally, the rated current must be larger 20% than actual current.

Over 600A cusrrent customized is available.
