1.7.1 Charging
Battery charging is indicated by a steady orange state on the BATT LED. This LED state also
indicates a maintenance operation (1.7.3). The BATT LED is steady green when the battery is
fully charged. The battery takes about 2 hours to charge.
Overcharging protections:
•
Temperature Limit: Battery temperature over 55°C
•
Voltage Limit: Battery voltage over 9V
•
ΔT: Battery temperature increasing too quickly
•
-ΔV: Battery voltage decreasing too quickly
If any of these conditions occurs, the charge is interrupted.
1.7.2 Discharging
During battery discharge, the BATT LED blinks:
•
Green: when the remaining capacity is over 50%
•
Orange: when the remaining capacity is under 50%
Overdischarging protection:
The battery controller shuts down the TAP if the battery voltage goes below 6.5V.
1.7.3 Maintenance
Cold battery
If the battery' s temperature is below 10°C, the TAP slowly heats up the battery (with medium
rate charging) to prevent potential thermal shock damage.
Deep discharge recovery
If the battery' s voltage is too low, the TAP charges the battery at medium rate, until the
voltage reaches an appropriate level.
