Cosun Active 4S balanced 12V LFP Battery Cell Equalizer
Short Description:
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 de...
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
