2.7.2- Equalize Mode after End of Charge Mode
Figure 2. Charge profile for Equalize Mode
Figure 2 defines the charge profile for the Equalize Mode. After going through
bulk charge and Constant Voltage modes, the charger will reduce its output cur-
rent to Top-Off Current (Ito) until one of the two possible outcomes occurs:
(1) Battery voltage rises to Equalize Voltage (Vequ) or
(2) Equalize Time-Out (Tto) is reached.
Once one of these two possibilities occur, charging will stop and the 1620 will set itself
to Off Mode; the charger remains in standby until restart voltage (Vrst) is reached.
