In order to optimise the efficiency of the battery, the battery automatically executes a learning cycle at
periodic intervals, wherein the actually usable capacity of the battery is automatically determined.
In this learning cycle, the battery must cover the SOC limits of 100% and 12% as frequently as possible.
The learning cycle starts at 100% SOC (battery full) and ends at 12% SOC. If both incidents occur in succession
and, in the meantime, the energy is not charged more than 20% SOC, then the learning cycle is evaluated as
“successfully executed”.
The higher the frequency of execution of this learning cycle, the more precise is the SOC calculation.
The higher the frequency of execution of this learning cycle, the more the energy that the battery can save
and transfer.
