PRODUCT INTRODUCTION:

BMS is a Smart CAN and Bluetooth based management system used in large current applications. Supporting passive balancing as well as Active (using custom code) which complies with overall battery protection features like overcharge, over discharge, over current and over temperature protection etc. 

            The BMS communicates with the PC or Charger and Controller via CAN and supports CAN 2.0 it also supports mobile connection via a dedicated mobile app, supporting Android OS. The app is used to monitor live battery working status and can be used to modify the working parameters of the BMS and also acts as an emergency switch to switch off charging as well as discharging. Having a Robust design and being small and extremely light this BMS can be used in Lithium Battery.

              The default is the li-ion parameters however when you connect your phone to the BMS via Bluetooth, you can click and set up lifePo4 / LTO parameters.

TECHNICAL DETAILS:

  • Single cell voltage detection range 1.5V-4.6V. 
  • High precision detection cell voltage error is less than 5MA 
  • Charging current 50A 
  • Discharge current: 120-160A
  • Continuous 320 Peak (Depending on which BMS model you buy) 
  • Balance current :200MA. 
  • Controlled balance mode, when you start charging, the voltage difference can be detected by the voltage difference greater than the set value. 
  • High-precision coulomb counter function temperature control detection Hall speed measurement 
  • Bluetooth connection: support for android with Bluetooth 4.0 
  • Support cells: Support Li-ion, Lipo, 18650, Lifepo4, LTO and so on 
  • Voltage accuracy: Single cell voltage detection range (1.5-4.6V), accuracy error within 3 mV 
  • Overcharge protection 
  • Over discharge protection 
  • Short circuit protection: Up to 320A 
  • Overcurrent protection: maximum 300A 
  • Current detection: within the current range of the BMS 
  • Temperature control protection: The protection board has built-in balanced temperature control, power temperature, and can be connected with 4 temperature sensors to prevent high temperature danger
