Unique Cosun Active Lithium battery Balancing Technics
Battery systems are affected by many factors, the most important one is the cells unbalancing. Without the balancing system, the individual cell voltages will differ over time, battery pack capacity will decrease quickly. That will result in the fail of the total battery system. Thus cell balancing acts an important role on the battery life preserving.
Active cell balancing methods remove charge from higher cells and deliver it to lower cells while passive methods remove the excess energy from the high cells through a resistive element until the charge matches those of the lower cells in the pack. The advantage of passive balacing is the relatively low cost and complexity, however the disadvantage is that it results in a high amount of energy loss.

Cosun spent 5 years to develop her owned reliable, affordable and high efficient activbalancing technology featuring 2A balancing current, 9mA working current and 30uA stand-by power consumption.
Unlike 99% of the passive balancing board in the market with complicated functions to meet various application, cosun active balancing is purposely designed to fit the BESS's needs and reduce all the un-necessary features for higher reliability and simplicity and low cost.
