CHARGE METHODS FOR NI-CD BATTERIES - CONTINUED

(3) General Specifications
Because this system is currently used only as a rapid
charge method for Sealed Lead Acid batteries, the
specifications are not included here.
(4) Precautions
This charge method is basically the same as the
voltage-controlled charge system, and it is not appro-
priate for charge Ni-Cd batteries.
Constant-voltage, Constant-current Controlled
Charge system
This is the basic charge system for Sealed Lead Acid
batteries, and it is not recommended for charge Ni-
Cd batteries.
(1) Mechanism
The charge voltage of Sealed Lead Acid batteries
rises sharply at the completion of charge and is
subsequently maintained at that level. The constant-
voltage, constant-current controlled charge system
utilizes these charge voltage characteristics to
complete (control) charge using only a constant-
voltage power supply with no external control. When
the battery voltage is lower than the constant voltage,
charge is carried out in the constant-current range,
and when the battery voltage reaches the level of the
constant-voltage, the charge current is decreased to
a trickle current.
This is the recommended charge control system
for Sealed Lead Acid batteries.
In comparison with the voltage-controlled charge
system, this method is capable of increasing the
charge level by the amount indicated by the
shaded area in Fig. 12. However, just as for the
voltage-controlled charge system, the setting of
the detection voltage is extremely difficult when
charge Ni-Cd batteries.

(2) Features
Because this method is used only for charge Sealed
Lead Acid batteries, the features are not included
here.
(3) General Specifications
Because this method is used only for charge Sealed
Lead Acid batteries, the specifications are not in-
cluded here.
(4) Cautions
The charge voltage characteristics of Ni-Cd batteries
exhibit a peak at the completion of charge, and
subsequently drop. Therefore, if the constant-voltage,
constant-current controlled charge system were to
be used to charge Ni-Cd batteries, the charge cur-
rent would be increased again, and thermal runaway
would occur. This method is not suitable, and is not
recommended for charge Ni-Cd batteries.
