Nickel-cadmium battery working principle and repair methods

Charge NiCd batteries at a constant current in the range of 0.05C to greater than 1C. Some low-cost chargers use absolute temperature termination of charge. Although simple and inexpensive, this method of charge termination is imprecise. A better method is to terminate charging by detecting a voltage dip when the battery is full.

CHAPTER 4 NICKEL-CADMIUM BATTERIES

A typical charge starts at constant current (20A per 100 Ah 5-hrou rated capacity) and continues at the current until the cell voltage rises to a predetermined voltage limit (1.55 volts per cell at 25°C). The voltage during charge then becomes constant and the current tapers quickly to a final float current. Table 4-2 gives typical charge

6 FAQs about [Charge and discharge current of nickel-cadmium battery]

How stable is a nickel cadmium battery?

Nickel–cadmium batteries, unlike some other battery systems, show very stable voltage of 1.2 V for the majority of the discharge process up to the point where there is a “knee” in the curve and a sharp drop at the end of discharge (Fig. 4.6). The point when the battery reaches 0.9 V is considered the end of discharge and full capacity.

Why is overcharge a ni cadmium battery a problem?

The overcharge is an undesirable process in Ni–Cd batteries because it leads to generation of gasses and increase in both pressure and temperature that can catastrophically damage a battery. Since most nickel–cadmium batteries are sealed, a special design approach was needed to control the overcharge and to prevent any damage to battery.

How do you keep a nickel cadmium battery fully charged?

A useful procedure to maintain full capacity of nickel–cadmium batteries at all times is to use trickle charge simply to offset the self-discharge rate and keep the battery fully charged. If this is not possible, a battery should be stored in cool conditions.
