Rework charge cycle: The charge counter is increasing decreasing also if the real value is maybe not defined (definition is done for example by a completed charging cycle). This caused some problems with invalid displayed charge per centage values. To avoid this the state of an unknow counter value was introduced. The indication is done by converting the counter into a negativ value.
