Thor VM2 with with Microsoft Windows Embedded CE 6.0 User Guide
The UPS battery is automatically charged when the Thor VM2 is placed in a powered
dock, provided the safe charging temperature conditions below are met.
When external power is removed, the UPS automatically powers the Thor VM2 with no
user intervention. When running on UPS power, the power management timeouts may
be different than when vehicle power is applied.
The UPS allows the Thor VM2 to continue operation when not mounted in a dock or
when the vehicle battery is being swapped. When fully charged the UPS battery is
designed to power the Thor VM2 for a minimum of 30 minutes at temperatures of -20ºC
(-4ºF) or greater.
If operating on UPS power and the UPS battery becomes critically low, the Thor VM2
performs a controlled shutdown.
If there is no external power available, there must be 10% or greater power in the UPS
battery or the Thor VM2 does not power on.
The UPS status LED and the Battery Control Panel can be used to monitor the state of
the UPS battery.
Safe Charging Temperature Range
The internal temperature of the Thor VM2 is the trigger for UPS battery charging.
•
The UPS battery is not charged when the internal Thor VM2 temperature is below 0°C
(32°F). This corresponds to an ambient (room) temperature of approximately -10°C
(-14°F).
•
The UPS battery is not charged when the internal Thor VM2 temperature is above
45°C (113°F). This corresponds to an ambient (room) temperature of approximately
35°C (95°F).
•
If the UPS battery cannot be charged due to a temperature extreme, the
is amber. Move the Thor VM2 to a different location to charge the UPS battery.
When the Thor VM2 is operated in an environment where the UPS battery is not able to
charge due to temperature extremes, the Thor VM2 should be removed to a location
within the safe charging temperature range during off hours. A discharged UPS battery
cannot protect against data loss in the event vehicle power is interrupted.
Charging Timeout
•
A fully discharged UPS battery normally recharges in less than 4 hours when the Thor
VM2 is in a powered dock and within the safe charging temperature range.
•
If the UPS battery is not charged before an 8 hour (or 4 hours for some earlier
software revisions) timeout period expires, the
is amber.
•
The charge timeout is reset if charging resumes upon application of external power.
Safety requirements restrict the temperature at which the Li-Ion UPS bat-
tery can be charged. Charging is disabled if the ambient temperature is out-
side of the 0ºC to 35ºC safe charging range. In order to maintain UPS
charge the Thor VM2 should have power applied while the unit is within the
safe charging range for at least an hour each day.
