Item for detection
Battery connection
Time detection takes
10 ms
×
1 time = 10 ms
Conditions for detection
Constantly detected every 400 ms (when more
than a specified amount of charge-current is
flowing, this detection is omitted).
Presence of a battery
Presence of a battery and detection of normal
temperature
Presence of a battery and detection of normal
temperature
Presence of a battery and detection of normal
temperature
Completion of charging for a connected battery
Presence of a battery
Presence of a battery and detection of normal
temperature
Charging is in progress
Battery temperature 4 consecutive 50-ms periods = 200 ms
1.0-V
3 consecutive 25-ms periods = 75 ms
2.0-V
3 consecutive 200-ms periods = 600 ms
2.9-V
3 consecutive 200-ms periods = 600 ms
3.9-
Excessive voltage
Charge completion
4 consecutive 1.6-s periods = 6.4 s
3 consecutive 400-ms periods = 1.2 s
3 consecutive 3.2-s periods = 9.6 s
Excessive charge
current
Adapter voltage 1
3 consecutive 400-ms periods = 1.2 s
4 consecutive 50-ms periods = 200 ms
Constant detection (whenever charging has
stopped)
Constant detection (during charging)
Constant detection
Adapter voltage 2
Adapter voltage
3a/3b
Notes: 1. The timer for precharge 1 and 2 and the charge timer continue to count in the adapter-voltage standby
modes and battery-temperature standby modes. Counting by these timers restarts from the previous value
when charging resumes.
2. Detection of adapter-voltage abnormality (5.2/4.95/6.3 V) and battery connection is constant.
4 consecutive 50-ms periods = 200 ms
4 consecutive 200-ms periods = 0.8 s
