    Cosun partners with German PV and power electronics experts build out the high efficient,reliable
    active full-bridge DC-DC converter equalizer for 12.8V 4 strings of 3.2V Lithium battery cell (LFP,LTO,
    LMO 18650, 26650, etc) which is widely use for replacement of  traditional 12V lead-acid battery for
    sustainability.It works perfectly for lithium battery capacity up to 100Ah which most of the passive balance
    cannot handle well with reliability. Thanks to Cosun’s patented full-bridge design, forget about the expensive
    module IC from ADI or TI which is 3-4 timer higher than the common IC Cosun is easy to get in the market,
    Cosun active balance is well below competitor’s price and almost equals to the cost of most passive balancer.
    Here below is a quick rundown of Cosun 12.8V 4S balancer:
    1. 2A balance current,
    2. Active Full-Bridge Converting balance, transfer battery energy from high to low without loss
    3. Voltage range: 8~20V
    4. Ultra-low operating and stand-by current (9 mA & 30 uA only) for much longer storage/
    transportation time
    5. Over-charge and Over-discharge Protection and auto-recovery for single cell and battery pack
    6. Protection for charging,discharging and short-circuit,Thorough Current Alarm
    7. 1%±30mA High Precision Current Measurement, Over 10mV High Precision Voltage Measurement
    and Less than 2℃ High Precision Temperature Measurement
    8. Less than 5% High Precision SOC Calculation. 32 User calibration dictionaries can be configured
    9. Battery SOH Self-Learning
    10. RS485 communication
    11. Module design,work with BMS or work independently.
    12. Compact size: 184 x 83 x 16mm

  • Cosun BMS 80-80PX

    Cosun Active Balance BMS is purposely developed by Cosun and our German PV
    installer partner for LiFePo4 battery, by adopting an innovative module design which
    consists of active balance module, main control module and switch output module,
    a custom BMS can be easily made for 4~64 string of lithium iron phosphate battery.

    Module DesignIntelligent   *   Cost Effective
    Flexible for 4-64 String           Inverter auto-matching      3-4 times less than competition

    1.5A Balancing Current
    Ultralow  Operating & Quiescent Current: 100mA / 9uA

    Result in
    More Usable Capacity and Longer Cycle / Life time

    How Does Cosun Smart Battery Clound Work

    Cosun Battery Cloud
    Remote Control of Cosun Battery System
    1. 
    Monitoring / History Data Record
    Knows your battery info anything,anywhere
    2. Diagnostic Function
     Your battery doctor is always online to
    watch the health of your battery,don’t
    wait for the problem but fix it before error.
    3. Firmware Updating online/remotely
        Reduce installer/service engineer site visits
    to the minimum,save time and money.
    4. Data Transfer Unit (DTU)
    Easy and simple to have the battery cloud
    system work, just add the DTU, connet it to Internet.
