Embodiment Construction

[0058] Refer to Figure 4 As shown, the serial-type automatic variable speed charger 30 for nickel-metal hydride and nickel-cadmium batteries of the present invention has a smaller volume than a general commercially available fast charger, and is close to the volume of a general fast charger, that is, the exchange type built in the housing 31 power supply( Figure Four The power of (not shown) is similar to that of a general fast charger. The surface is provided with a charging slot 32 for charging several batteries. This embodiment discloses that four batteries can be charged, but it is not limited to this. The bottom of the casing 31 can be directly provided with a plug 33 connected to the AC power source, or an extension cord 34 can be connected with a plug. There is no need for an external transformer, and the volume is light and easy to carry. How to use this low-power switching power supply to make the charger achieve the function of extremely fast charging is an ingenious de...

Abstract

An automatic variable speed charger of nickel- cadmium and nickel-hydrogen cell series type consists of shell for containing charging component, charging groove for laying cells to be charged, converter for converting AC to be DC to provide DC power for charging and providing reference voltage to charging control unit, time control unit for controlling on-off state of each independent switch, cell number and voltage detection unit for detecting cell voltage and cell number, voltage and current regulation unit for controlling charge voltage and charge current as well as charge time.

Description

1. Technical Field [0001] The invention relates to a series-type automatic variable speed charger for nickel-hydrogen and nickel-cadmium batteries. 2. Background technology [0002] With the increasing popularity of 3C portable electronic products, the demand for batteries has also increased. Since disposable batteries need to be discarded after they are used up, this not only increases the cost of use, but also causes environmental pollution problems. Therefore, compared to disposable batteries, rechargeable batteries (or secondary batteries) can save money and reduce environmental pollution caused by waste batteries. Therefore, the number of uses continues to increase, and the demand for corresponding battery chargers is also increasing. [0003] Some of the existing chargers for nickel-hydrogen or nickel-cadmium batteries use parallel charging, and some use series charging. Among them, the parallel charger has its drawbacks because it is not easy to select and arrange electron...
