Bugfix Battery charge complete event: In previous version it could happen that the battery charge state was set to 100% even the battery was not completly charged. Rootcause was that the external charger IC signals sometimes completion because e.g. the connection between charger unit and OSTC is disconnected within a short time slot. This may happen while the user is trying to get the OSTC in a good charging position. To avoid this the state machine now checks the voltage everytime for valid charging complete range before a charging complete is signaled.
