REC is proud to announce the REC Active BMS for four cells
connected in series. Designed to provide unsurpassed battery
management in 12 volt systems, the REC Active BMS delivers 2A
cell equalizing with active balancing and synchronous flyback bidirectional energy transfer from cell to pack and pack to cell.

Features:

  • Li-PO, LiFePO4, LiFeYPO4, LiCoO2, LiMnNiCo and LiMnO4 Lithium-Ion chemistry
  • 4 series connected cells per unit
  • high efficiency 2 A bi-directional active balancing (pack to cell and cell to pack)
  • IP65 protection enclosure, AMP 35 pin water resistant connector
  • 2 – 5 V measuring range, 2 mV accuracy
  • up to 2 digital temperature sensors
  • shunt current measurement
  • robust and small design
  • galvanically isolated RS-485 and CAN communication protocol
  • two programmable fused relay output
  • two programmable fused digital output
  • ON/OFF switch
  • LED and buzzer status indication
  • bootloader
  • error LED + buzzer indicator
  • PC user interface for changing settings, data-logging and firmware update
  • compatible with REC LCD touch display for monitoring
  • compatible with Victron inverters for solar applications
  • Seamless CANbus integration with Wakespeed’s WS500 Advanced
    Alternator Regulator

Microcontroller:

  • 60 mW self power consumption with disabled CAN and all outputs

RS – 485 communication:

  • galvanically isolated RS-485 communication
  • Slave configuration
  • RS-485 driver primary side supply is activated with Master connection to save energy consumption
  • fully compatible with REC LCD touch display and PC user interface BMS Master control

Active Balancing:

  • 2A cell equalizing with active balancing with synchronous flyback bi-directional energy transfer: cell to pack and pack to cell
  • top side and bottom side balancing prolong the cycle duration due to the weakest cell

Outputs:

  • two fused relay outputs with NO and NC pins
  • two fused galvanically isolated/non-isolated digital outputs with PWM option

Galvanically Isolated CAN:

  • galvanically isolated CAN
  • 100, 125, 250, 500, 1 MHz bit-rate selection
  • message programming
  • disable option

Complete wiring of ABMS connector:

  • 5 cells wires (l = 1m)
  • relays, digital output wires (l = 0.5m)
  • RS485 cable (l = 0.5m)
  • CAN cable (l = 0.5m)
  • remote ON/OFF switch (l = 1m)

    REC SI BMS

    $559.95 $535.27

    The REC SI BMS has custom profiles that integrate on the RS485 network to several well known Solar Inverters.

    These include:

    • Sunny Island
    • Victron
    • Studer
    • Solax
    • GoodWe

    During the day PV powers the house and charges the battery pack. If you’re not using all the electricity that the solar PV system is generating, then the system will ensure that any surplus energy is used to charge the battery pack. Once the battery is fully charged, if there is still more solar electricity being generated, this will be exported to the grid. At time of low solar generation (night or cloudy day) the solar PV panels have a reduced or zero output, but the battery system can discharge the stored electricity, providing you with renewable-generated electricity at no additional cost. Once the battery is discharged, if you need to use more electricity, you buy it from your electricity supplier.
