Smart Balancer for LiPo/Li-ion batteries pack
Model:BMS16 v2.0

Chargery BMS16 is designed special for LiPo & LiFe 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 BMS16 uses advanced ADC measurement technology, high accuracy, high voltage and high current detection circuit. The maximum voltage measurements tolerance is within 5mV at up to 16S LiPo battery (69V)
  2. Charge/discharge current up to 300A.
  3. Support regenerative braking, during braking operation can charge the batter pack and the discharge power (Wh) will decrease to response to the braking power.
  4. BMS16 calculate and display the charge and discharge power (Wh), generally the battery rated power is rated voltage multiply rated battery capacity.
  5. TFT LCD screen that provides rich information including current, voltage, power, capacity, control status, SOC and temperature and so on.
  6. BMS16 features a maximal safety protection, within the range parameters can be setup, BMS16 will alarm and cutoff charge or discharge according to usersí» setup, out of range of parameters, and trigged absolute maximum ratings BMS16 will force to cutoff charge or discharge to prevent the battery from fire.
  7. Minimize the power consumption by draw current from all cells or external power supply.
  8. Dual power design, the unit can be powered by all cells or external power supply.
  9. 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 usersí» setup, the feature can prevent any cell connection from loosing.
  10. 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.
  11. Charge relay and discharge relay are controlled independently.
  12. Two temperature sensors monitor battery temperature on different location.
  13. Supports upgrading the firmware program by USB port.
  14. BMS16 provide users the maximal flexibility, key parameters can be programmed.
  15. BMS16 display battery SOC or called battery gauge similar with car dashboard. Cell count, battery pack voltage and battery gauge (%) is displayed simultaneously.
  16. 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.

Protection Functions:

  1. Cell count error protection
  2. Over charge protection
  3. Under voltage protection
  4. Over current protection when charge or discharge
  5. Over temperature
  6. Over differential cell voltage
  7. Over differential battery temperature
  8. under SOC protection

on new version, continuous charge and discharge curren updated to 300A, 600A burst.

Current Sensor measure charge and discharge current up to 300A with one current shunt

300Acurrent shunt
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. relayDelay
The 12V mechnical relay is optional. 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. relay
