Circuit Of Float-type Battery Charger
Figure 1 is one kind of Nickel-cadmium battery and Ni-MH battery charger circuit. This circuit is mainly used to charge the battery of nickel-cadmium and nickel metal hydride (5 #, 7 #). Charge mode is the power float type. The float means the power is continuous DC but not by the pulse voltage type. Battery float charge type is the most commonly way to charge the household batteries, the advantage is the simple circuit and the disadvantage is difficult to reach the battery's nominal capacity. This disadvantage is not obvious to the small-capacity rechargeable battery, but to the large capacity battery, this disadvantage will not only shorten the use time of battery, but also shorten the battery life, so to the large capacity battery such as the electric bicycle, we'd better not use the float charge type.
