2.9.7.1Charge Function
A. FOR NIMH BATTERYWhen the charger module charges a 9 cells NiMH battery, 0V and T/ t, max T and - v detentions
will be used as the main methods to determine the full charged battery. To ensure safety for the
battery and system, fast charging NiMH battery after long period of storage time, the module will
disable 0V detection during a short “ hold-off” period at the start of fast charging. Also when
‘charge in use’ the 0V and -V...

Major Chips Description2-97When system on if Adapter not inserted and battery voltage lower than BL3 voltage , then system
will be turned off by the charger module.
In addition, when system sends a ‘disable’ signal to charger module, system will be turned off by
the charger module immedietly.
2.9.7.3Safety Concerns
For safety, the charger module inhibits charging until the battery voltage and temperature are
within the configured ranges. If the voltage is less than the low voltage threshold , the...
