12.6.4 Battery Mode
When in Battery Power Mode, the system maintains the current patient and can scan or
perform other operation normally.
12.6.4.1 Battery Life Cycle
Battery life cycle can estimate using cycle count. If cycle count reaches up to 250 cycles,
Battery will be expired.
Capacity ± 1,770mAh @ after 250 cycles (60% of the standard capacity @RT)
- Charge: 1.5A 4.20V, CCCV 150mA cut-off @ RT.
-Discharge: 15A, 2.5V cut-off @ RT
•
Assumption : 1cycle/day
For example, user uses function and discharge 1 cycle per day, battery lifecycle is 250
days (in workding day).
For example, user uses battery function and discharge 0.5 cycle per day, battery
lifecycle is 500 days (in workding day).
•
Definition of Cycle
Battery is monitoring total discharge-capacity for Cycle-count.
1 cycle = total usage sum of battery capacity become 90%.
