Note 2:
Specification applicable during charge cycle with T
= 0 C to +70 C.
Note 3:
One time slot out of every 16 available slots gets a Cell Test.
Note 4:
One time slot out of every 32 available time slots gets a charge pulse.
Note 5:
0.48 seconds is one charge time slot. A complete cycle of 4 time slots (one charge time slot per cell) is 1.92 sec.
