![]() ![]() How does the CBM work if the charging current is higher than the balancing current? The balancing current of the CBU module is about 1.7A. If the charging current is higher than the balancing current, the voltage will continue to increase gradually. If the charging current is lower than the balancing current, the voltage will decrease slowly. The diagram shows that the balancing of the CBU starts at 3.67V and the voltage is reduced to 3.64V and does not keep increasing as fast as without the balancing. However the charging current is 2A while the balancing current is 1.7A so the voltage starts increasing slowly again. This is a proper way the CBM operate when the balancing the cells. | |
