Problems solved by technology

However, in this way, the power of the built-in switching power supply needs to be relatively large, that is, the volume of the coil assembly for transforming needs to be increased, such as image 3 As shown, the ultra-fast charger 20 connects the switching power supply externally to form an AC / DC transformer 21, and then connects the plug 22 or the extension cord plug 23 to the AC power supply, which is more inconvenient to carry and increases the cost.

Embodiment Construction

[0060] refer to Figure 4 As shown, the Ni-MH, Ni-Cd battery series automatic variable-speed charger 30 of the present invention has a volume smaller than that of a general commercially available ultra-fast charger, and is close to the volume of a general fast charger. power supply( Figure four (not shown) is similar to the power of a general fast charger, and its 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 thereto, and the The bottom of the casing 31 can be directly provided with a plug 33 connected to an AC power source, or can be connected with an extension cord 34 to provide a plug without an external transformer. The volume is light and compact, so it is convenient 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 design on the charging circuit of the present inven...

Abstract

The invention discloses a nickel-cadmium and nickel-hydrogen cell series type automatic variable speed charger consisting of a shell, a switching type power supply, a battery, a charging controller and a microcontroller. The microcontroller controls a voltage regulating unit and a current regulating unit. The current regulating unit is connected to a current sensing unit. The charging voltage and current are decided by the number of the sensing battery, and the charging current is in inverse proportion to the number of the battery and is automatic variable current. The number of the variable current segment is that of the battery, so that the multi-segment variable speed charging mode is formed, and the fully charging time is automatically regulated according to the battery number.

Description

1. Technical field [0001] The invention relates to a series-connected automatic variable-speed charger for nickel-metal hydride 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 use, it not only increases the cost of use, but also causes environmental pollution problems. Therefore, compared with disposable batteries, rechargeable batteries (or secondary batteries) can save money and reduce environmental pollution caused by waste batteries. Therefore, the number of uses is increasing, and the demand for corresponding battery chargers is also increasing. [0003] Some of the chargers of existing Ni-MH or Ni-Cd batteries adopt parallel charging, and some adopt serial charging. Among them, the parallel charger has its disadvantages because the selection and configuration of electronic control parts ar...
