Controlling battery group charging and discharging involves blocking charging and discharging if upper and lower group capacity limit values are reached respectively

摘要

The method involves determining upper and lower capacity limit values lower and higher than the fully charged and discharged capacities respectively and a defined capacity between the limit values. Charging and discharging take place when the computed capacity of the group is between the limit values. When the capacity reaches the upper limit, charging is blocked until it reaches the defined capacity. If it reaches the lower limit discharging is blocked until the defined capacity is reached.
