CHARGE METHODS FOR NI-CD BATTERIES - CONTINUED
(1) Mechanism
While the AC power is being supplied, the battery is
disconnected from the load and is charged by a very
small current which only replenishes the self-dis-
charge of the battery. Only in the event of an interrup-
tion in the AC power supply does power flow from the
battery to the load.

(4) Precautions

(1) Mechanism
The charge voltage at the completion of charge is
detected (the detection voltage can be freely set) by a
voltage detection circuit inside the charger, and the
charger switches from rapid charge to trickle charge.
To compensate for temperature-related fluctuations in
the charge voltage of Ni-Cd batteries, temperature
compensation is added to the detection voltage.
Voltage-controlled Charge System (for
Reference Only)
The trickle charge current for use as a standby
power supply should be set to a level at which
charge will be completed by time of the next
discharge, taking into consideration the frequency
of discharge and the discharge current.
If recovery charge at a relatively large current (for
example, 0.1 CmA) is required, combine trickle
charge with some other suitable charge control
system (for example, timer-control charge).

Mainly used as a standby power supply for
emergency lights and other disaster-prevention
equipment.
The main purpose of trickle charge is to replenish
the self-discharge of the battery, using a very
small charge current of 0.02 to 0.05 CmA.
It takes many hours to completely charge.
