Reimplemented charger status generation (deactivated): Sometimes the original implementation never reached the state fully charged for unknown reason. The code already contained a function which set the status to fully charger even it was not signaled by the charger (in case voltage is > 4.1V). The new implementation changed the handling of the detection and the OSTC showing the problem now reaches the fully charger status. As the new implementation is still under test it is deactivated => original implementation is active per default

  OSTC3 Warnings:
		niedriger Batteriezustand (
		zu hoher oder zu niedriger Sauerstoffpartialdruck (ppO2) 0.2 - 1.6
		zu hoher CNS (Gefahr der Sauerstoffvergiftung) 90%
		zu hohe Gradientenfaktoren 90 - 90
		Missachtung der Dekostopps (der �berschrittene Dekostopp wird rot angezeigt) 0 m
		zu hohe Aufstiegsgeschwindigkeit 30 m/min
		aGF-Warnung: die Berechnung der Dekompression wird �ber alternative GF-Werte durchgef�hrt
		Fallback-Warnung bei ausgefallenem Sensor
