SPF-F-36-30 BMS

Specification

  1. With a communication port for SMBus interface via USB tool bridge to PC to gather battery information, helpful for engineering or R&M services.
  1. Monitoring battery SoC and SoH, such as amperes, volts, capacity; temperature, protection status and cell balance, cycle life times, event records etc.  
  1. With circuitry of blocking back electromotive forces(BEMF), and filter circuitry against noises or interference.
  1. Smart two-way cell balance design for both in charging and in quiescence.
  1. LED display to show battery capacity, based on Coulomb Counter and, to show protection occurrences.
